Plate I.--AMPELIS CEDRORUM, Sclater.--Cedar-Bird.
|The Cedar-Bird, though mainly a denizen of the wooded regions of North
America, and occasionally of cultivated fields and orchards, has been
known to nest from Florida to the Red River country. But, wherever
found during the non-breeding period, it is the same gregarious, nomadic
species.
After the beginning of October, the search for food so completely
engrosses the attention, that it is not until the latter part of May, or
the beginning of June, that the flocks break up into pairs.
Nidification now becomes the all-absorbing passion, and the birds
after mating, which business is generally conducted in a quiet and
unostentatious manner, repair to the woods or hedges in quest of
a suitable shrub or tree in which to establish a home. This matter
requires considerable labor and care; and, ordinarily, no little time is
devoted thereto.
The place usually selected, is a retired and unfrequented thicket or
nook; or occasionally, an orchard in close proximity to an occupied
dwelling. When the former, the cedar, with its tall, nearly vertical
branches and dark green foliage, is, of all our forest-trees,
pre-eminently fitted to receive, support, and conceal the nest; when the
latter, the apple is accorded the preference.
Having chosen the locality, the birds waste no time in idleness, but
apply themselves to the task of building, with the most commendable
zeal and perseverance. Each bird has its allotted part of the work to
perform: the duty of the male being to collect the materials; that of
the female, to shape and fix them in their proper places. Occasionally
the latter, when not thus occupied, accompanies her partner in his
frequent journeys, and assists in collecting and bringing in his load.
The time employed in the labor of construction, making due allowances
for recreation and rest, is between five and six days.
In form, the typical structure is nearly hemispherical, and presents a
rather neat and elegant appearance. It is compactly made, and, in the
generality of instances, exhibits anything but bulkiness. In position,
it rests upon the horizontal limb of a tree, or is wedged in among
several upward-growing branchlets, at elevations varying from three to
twenty feet.
During the period of nidification, almost any substance, having the
requisite flexibility and strength, is in demand; consequently, the
materials of composition are as varied as they are numerous, and depend
in a great measure upon the _environment_. In thickets, small twigs,
stems of grasses, dried leaves, lichens, and the tendrils of the vine,
make up the bulk of the structure; but in places situated in close
proximity to houses, wrapping-twine, strips of rags, and such other
substances as are ready prepared and accessible, are utilized.
The lining is generally fine roots of grasses, bits of string,
flower-stalks, lichens and tendrils. The cavity seldom exceeds three
inches in width, and scarcely two and a half in depth; while the
external diameter varies from four and a half inches to five; and the
height, from two and a half to three.
The specimen which we have figured, and which may be regarded as typical
in its character, was obtained in the vicinity of Bridgeton, N. J., in
the summer of 1878, and was neatly erected upon the horizontal branch of
an oak, and held in position by two nearly vertical branches of the same
tree. It was placed at a height of nearly twenty feet above the ground,
and consists almost exclusively of fibres of the long greenish-yellow
lichens which constitute so conspicuous a feature of the trees of that
locality, in their sylvan retreats. Externally, besides a few fine
rootlets, there is noticeable much white wrapping-string, which
relieves, in a great degree, the monotony of the fabric. Internally,
there is the same green moss-like lichen. The cavity is beautifully
symmetrical, and measures about three inches in width, and nearly two
inches in depth. The external diameter is five inches, and the height,
two inches. The nest is most elaborately finished, and is evidently the
workmanship of superior mechanics. The Plate represents it three-fourths
the natural size, placed upon an apple branch.
Among other fabrics which the writer possesses, is one which was
obtained in June, 1871, in Germantown, Pa., saddled upon the horizontal
branch of an apple-tree. It is rather firmly and compactly built, and
is composed, exteriorly, of stems of the common timothy, fine rootlets,
dried leaves of the mullein, and green leaves of the apple, which are
held together by broad strips of colored rags, bits of lint, and divers
strings, the latter constituting a prominent feature. Interiorly, there
is a promiscuous lining of flower-bearing stems, fragments of strings,
fine roots of grasses, fibres of linen, and tendrils of some species
of cucurbitaceous plant. The nest is about four and a half inches in
external diameter, and nearly three in height. The cavity is three
inches wide, and two and a half inches deep in the middle.
This last model of architecture, as already remarked, was placed upon
the limb of an apple-tree, near its extremity, and barely at a distance
of fifteen paces from an occupied dwelling. The rags, etc., which form
such a prominent feature of the outside, were purposely furnished by an
inmate of the house. When first proffered, it was thought that the birds
would be slow to perceive the use to which they could be put, but not
so, for they entered into the idea with the most praiseworthy alacrity.
And even after the materials were no longer supplied, they would
repeatedly fly to the bush upon which they had been laid, as though
soliciting a continuance of such favors.
The birds having constructed their home, the female commences on the
day following its completion to deposit her complement of eggs. The time
thus spent varies from four to six days, and depends upon the number
which is to constitute a setting. Oviposition being accomplished,
incubation follows, sometimes immediately on the deposit of the last
egg, but, not generally, until the succeeding day. This is the exclusive
task of the female for nearly fourteen consecutive days. Although the
male does not assist in the labor, yet he shows himself to be a very
kind and attentive husband, by providing food for his partner, and
keeping a vigilant lookout for approaching enemies. This he signals by
a low single note, which the female quickly acknowledges, and instantly
the two timid creatures beat a hasty retreat to an adjoining tree or
shrub beyond the reach of peril, where they become passive spectators of
the demolishment of their home, with all its precious burden.
The eggs, which are from four to six in number, resemble those of the
Waxwing, but differ in size, being somewhat smaller. Their groundcolor
passes from a light slate to a dark stone-color. The markings are
chiefly blotches of dark purplish-brown, lighter shades of the
same color, and peuumbræ of light purple, either by themselves, or
surrounding the darker spots. In form, they are either oblong-oval, or
nearly spherical; and in length, they vary from .80 to .90 of an inch, and
in breadth, from .50 to .70 of an inch.

Plate II.--CONTOPUS VIRENS, Cabanis.--Wood Pewee.
|The Wood Pewee, like most of its congeners, has a somewhat extended
habitat, ranging from the Atlantic westward to the Plains, and from
Texas to New Brunswick. It visits the United States about the 15th of
April, and from this time until its departure for Guatemala in October,
it is principally an occupant of high-wooded regions with a scanty
growth of underbrush, and timbered river-bottoms.
But as the season advances, and the amatory feelings become awakened,
these shady retreats are deserted by a few individuals of more
venturesome disposition, and a temporary abiding-place is sought for
amid the stirring scenes of active farm-life. This generally occurs
during the last of May or the beginning of June, and is the prelude to
the more important act of mating, which follows.
The assumption of matrimonial relations, however, is not a matter that
is entered into without more or less consideration. Occasionally, much
time is spent in its preparation. This is presumably the case when a
young female is courted by some venerable male. But when an apparently
experienced individual is the object of his devotion, the state of
things is different. His advances are then either encouraged and
reciprocated, or they are declined, and the disappointed suitor
compelled to seek a partner elsewhere. It is probable, moreover, that
the same birds pair together on each return of the breeding-season,
unless prevented by death, or some other of the numerous vicissitudes of
life.
The ceremony of mating being over--which business is ordinarily of short
continuance, seldom lasting for a greater period than two days--the
newly-wedded pair now set out to discover a suitable place for the
building of a home. This is a matter of considerable moment, often
requiring the performance of long and extended tours of observation
and exploration. These reconnoissances generally last for a week, but
eventually result in the choice of a locality well adapted, as far
as the essential conditions of shelter and security are concerned, to
become the depository of a nest. The site generally chosen for this
important purpose is a tall open woods with a preponderance of ash or
oak trees; but where a time-honored orchard is the recipient of this
favor, which is sometimes the case, the apple, 011 account of the many
advantages which it possesses, is preferred above all other fruit-trees.
The site being mutually agreed upon, the happy pair proceed with all
possible dispatch and diligence to construct a domicile: the male to
collect and bring in the necessary materials; the female, to fix them
in their proper places, and also to give shape and symmetry to the
structure. The time devoted to this work varies with the industry of the
builders, the style of the nest, and the character of the neighborhood.
But, where the birds are laboring under the most favorable
circumstances, the task is easily accomplished in five days.
This admirable piece of bird-architecture, which rivals in beauty and
symmetry the nest of our little Ruby-throated Humming-bird, is either
saddled upon a living or dead limb that is horizontal and lichen-clad,
or else upon the crotch of a bifurcated branch, and is placed above the
ground at elevations varying from five to thirty feet. According to Nutt
all, "the body of the fabric" occasionally consists of "wiry grass or
root fibres;" but we have yet to meet with a nest with "_small branching
lichens_ held together with cobwebs and caterpillars' silk, moistened
with saliva," as that author remarks. In a structure before us, which is
typical in its character, small strips of inner bark plucked from trees
of chestnut and oak, bits of tow, and fragments of wool, circularly
arranged and compactly pi-essed together, are the prevailing
constituents. Externally, it is closely invested with the bluish-gray
crustaceous lichens which are so plentiful upon the trunks of certain
trees, and also upon fence-rails. In diameter, it measures three and a
half inches; in height, one and a half inches. The width of the cavity
is about two inches; the depth in the centre, three-fourths of an inch.
The most beautiful fabric, as well as the most compactly built, which we
have seen, was obtained in the spring of 1870, not far from Germantown,
Pa. It was placed upon a horizontal branch of an apple-tree, in close
proximity to a farm-house. Externally, it is thickly covered with
_bluish-gray crustaceous lichens_, which are held in place by a few
cobwebs, and fragments of the silk of caterpillars. The base consists
of dried stems of grasses, and on these is reared a neat and cosy
superstructure composed of the inner fibres of the wild and cultivated
species of the vine, and a slight sprinkling of wool. These materials
are variously interwoven, and arranged around the margin so as to form
a cavity. The dimensions of this nest are as follows: External diameter,
three and a half inches; height, one and a half inches; width of cavity,
two inches; depth in the centre, three-fourths of an inch. In the Plate
it is represented the natural size--built upon an oak branch.
In the details of form and dimensions, this nest differs immaterially
from specimens which we have met with and seen from other localities.
But wherever obtained, they will always be found to bear a very close
resemblance to one another, differing chiefly in the character of the
articles which constitute the inner arrangement. We will merely mention
one example which was taken by Mr. Welch, in Lynn, Mass., and which will
give our readers some faint conception of the extent to which variation
is often carried. This structure was placed upon a dead limb of a
forest-tree. Its walls were composed of small dry stems and vegetable
down, finely interwoven, and covered on the outside with lichens which
were cemented to it by a viscid secretion that was apparently supplied
by the builders. The base wras somewhat flattened, much thinner than the
walls, and composed of finer materials. The external diameter was three
inches, and the height one and a half inches; the cavity, two and a half
inches at the rim, and the central depth about one inch.
Having finished their home, only a day or so intervenes when
oviposition becomes the controlling instinct. The female now proceeds
to deposit her complement of four eggs, which she does on consecutive
days, at the rate of a single egg daily. This is followed, on the day
succeeding the last deposit, by the trying duty of incubation. Upon the
female devolves this arduous and irksome labor. For about eleven days
she is thus engaged, until her patience is finally crowned with success.
Although the male takes no part in this duty, yet he contributes his
share to the prosperity of the undertaking, by guarding his partner from
danger, and supplying her with the essential articles of food. When his
home is assailed by feathered enemies, if they are not more than a match
for his strength, he is not slow to wreak instant vengeance upon them.
But in the case of human depredators, where effort would be futile, no
exertion is put forth to cause desistance from any contemplated assault,
save a little scolding.
The eggs are four in number, and resemble in configuration those of
the common Phoebe-Bird. They are obtuse at one extremity, and slightly
tapering at the other. The ground is a rich cream-color, and is
diversified about the larger end with a wreath of purple and lilac
spots, which are large, and occasionally confluent. In length, they
measure .76 of an inch, and in width .54. It is pretty well established
that but a single set is deposited by any given pair of birds in a
season. Nests with eggs, however, have been taken during the last of
July, or the beginning of August; but whether a second laying or not,
we cannot say--possibly the work of birds whose early efforts had been
frustrated.
[Illustration: 040]
Plate III.--MIMUS. CAROLINENSIS, Gray.--Cat-Bird.
|The Cat-Bied is one of the most common and conspicuous of all our
feathered visitants. It reaches the United States from its Central
American home, on or about the 10th of April, and thence diffuses
itself over the whole country, northward as far as the Saskatchewan, and
westward to the Rocky Mountains.
Immediately upon its arrival, it seeks the shelter of dense woods,
or the security of waste fields and bramble-ridden hedges. In such
situations, among the dead leaves that lie scattered upon the ground,
it gleans a well-earned subsistence. But later, when the leaves begin
to appear, and with them an abundance of insect-life, these retreats
are deserted by a few venturesome individuals, and an abiding-place is
sought amid the quiet scenes of rural gardens.
A week or ten days, however, elapse before the sexes are ready to assume
conjugal relations. Being vigorous feeders, and living in the midst of
plenty,' they are seemingly all unconscious of the better and nobler
instincts of their being. But feeding eventually satisfies appetite,
and conduces to the awakening of the amatory forces from their hitherto
dormant condition. The males, by their altered demeanor, are the first
to show signs of change. We no longer observe them engaged in the
pursuit of the juicy caterpillar, or the gilded butterfly, with the
same energy and zest as before. Their aims are higher, their aspirations
loftier. Perched upon a small tree, or screened from observation by
dense clumps of bushes, with heads bent skyward, they startle the echoes
of woodland and valley with their strange, ecstatic music. But the
females still continue feeding, as though utterly oblivious of the
concert which is intended for their benefit. After a day or two thus
spent, they become less absorbed in such matters, yield to the potency
of song, and coyly emerge from obscurity to welcome and encourage their
would-be suitors. The period of courtship is short, and unattended by
any of those peculiar antics which characterize many species at this
time.
In the Middle and Western States mating occasionally commences as
early as the 25th of April, when the season is remarkably forward, but
generally about the first of May--seldom later. In the Territories, from
some unknown cause, it is delayed to a later period. Very little time is
wasted after this event has occurred, in celebrating the occasion, for
the pair soon begin to look for a proper nesting-place. This is a labor
not entered into without previous care and deliberation. Ordinarily
a week or ten days are spent in making a choice of locality. The site
selected is usually a brier, cedar, thorn-apple, or a bush in the
midst of a grove or hedge, seldom remote from a settlement. The nest is
sometimes placed in a maple, and when such is the case, the birds take
the precaution to build it pretty well up. During the summer of 1880,
my son discovered one in a crotch of the red maple, at an elevation
of thirty feet from the ground. This, however, is exceptional, as the
height usually ranges from three to about twelve feet. It sometimes
happens that an injudicious selection of locality has been made, and a
nest has been nearly completed before the mistake is discovered. In this
predicament, instead of "making the best of a bad bargain," the birds
ignore the site for another better suited to their purposes. The
situation being finally decided upon, both birds work diligently during
the cooler hours of the morning and evening, for five or six days, in
the construction of their home. In some instances, particularly during
moonlit nights, the work has been carried on long after twilight has
faded from the earth. Unlike the case of the Cedar-Bird, which we have
already cited, there does not seem to be any regular division of labor.
Both birds collect the materials, as well as arrange them in the
nest. When a suitable article has been found, the finder does not fly
immediately to the nest and adjust the piece, but indulges in short
flights from one object to an adjoining one, carefully surveying the
premises all the while, until within a few yards of the nest, when she
rapidly flies thither, and having disposed of her burden, goes off in
quest of others. Where accustomed to man, the Cat-Bird does not seem to
be much annoyed by his presence.
Nidification ordinarily commences about the 18th of May. The nest
is placed in various positions--sometimes 011 a horizontal limb,
occasionally in a crotch, but generally among the branches of the bush
upon which it reposes. The materials of composition are as varied as
they are numerous. In thickets, and also in places removed from human
habitations, a platform of dried leaves, slender sticks, or weeds is
used as a basis, on which is reared a superstructure of small twigs,
fine roots, herbaceous plants, bits of straws, pine needles, and other
materials which are common to such situations. But when a nest is built
in close proximity to the home of man, bits of string, strands of silk
or thread, and bunches of cotton or wool are appropriated, and made to
do excellent service.
From the foregoing remarks it is obvious that nests vary according to
changes in the _environment_. Hence, what is typical in one locality
might be deemed but a deviation from the normal form, when compared with
a nest of the same species found in an entirely different neighborhood,
and _vice versa_. Mr. Ingersoll describes a nest found near Norwich,
Connecticut, which was suspended between two small bushes in such a
manner that it had no other support than that afforded by a slender
spray from each bush; but the large mass of crooked sticks below offered
so many hooked ends and projections that the nest was very secure. The
writer describes elsewhere a nest that was carelessly made, and bearing
a close resemblance to the structure of the Maryland Yellow-throat,
which he supposed to be the work of young or indolent birds. Another, on
the contrary, showed superior workmanship. The outside of this cosy and
beautiful nest was composed of wool, raw cotton, strings, fragments of
lamp-wick, a slight intermixture of tangled silk, fragments of lichens,
etc., held _in situ_ by strands of silk. Upon this basis was built a
superstructure of fine rootlets, intermingled with patches of wool.
The nest which we have figured in the Plate was found in the vicinity
of Philadelphia, Pa., in the summer of 1876. It is represented the usual
size, and shown in its natural position upon a cluster of blackberry
branches. Exteriorly, it is formed of wrapping string, bits of thread,
fine roots, cotton ravelings, a few grayish lichens, and bunches of
discolored raw cotton in great quantities. Interiorly, there is a lining
of slender grass stems, which monotony is relieved in a measure by a
piece of lamp-wick. The external diameter is five inches, and the height
about two and a half. The cavity is three and a half inches, and the
depth an inch and a half.
Such facts as are detailed above, with innumerable others of a similar
nature that might be adduced, most abundantly and conclusively prove
that birds are not the dull, senseless, routine-loving creatures which
those who have some pre-conceived opinion to uphold, or cherished theory
to sustain, are wont to argue. Though many of their actions are purely
instinctive or mechanical, yet evidence is not wanting to show that they
are gifted with a faculty similar in character to that possessed by man,
but differing in degree. A thousand circumstances justify the
belief that they often reason _a priori_ from cause to consequences,
providently managing with a constant aim for future comfort, convenience
and necessity. Instinct is always the same thing, never advancing, never
retrograding. Reason tends to improvement, always seeking a higher plane
of existence. To say that changes in nest-building imply a _change of
instinct_, is to perplex the understanding by a perversion of language;
but to ascribe them to the operations of reason, influenced by motives,
seems to be the most rational view to take of the matter.
The nest being completed, which is usually the case in about five days
from the time of starting, a brief season elapses before any eggs are
laid. In the Northern States this happens about the third week of May,
and then only one is deposited each day, for four or five days. The
necessary complement being laid, the female immediately takes the nest,
and incubation follows. This is her exclusive task for a period of
twelve or thirteen days. While she is thus engaged, the male stations
himself close-by the nest, only departing therefrom in quest of food for
himself and partner. Should an enemy approach, he assails the
intruder with commendable fearlessness and boldness. Various snakes,
particularly the black-snake, are their inveterate foes. When an attack
is made by one of these wily creatures, both parents, heedless of
danger, often fly so close to the assailant as to lose their lives in
efforts to prevent the nest being ravished and despoiled. But in the
case of human depredators, knowing that resistance would be futile,
they seek to deter them from any contemplated sacrilege by the most
discordant cries and frantic gestures.
The young are objects of tenderest solicitude. Both parents vie with
each other in rendering them every needed service. While one is absent
from home in search of food for their rapacious appetites, the other is
guarding the nest and its precious charges with the most jealous care.
Earthworms, spiders, flies, caterpillars of non-irritating properties,
together with such berries as the season affords, are collected in vast
quantities, and fed to these helpless creatures. But as they increase in
size and age, other articles are added to their voluminous bill of fare.
In about twelve days from the time of hatching, the young are able to
quit the nest, and in six days more, are ready to be initiated into the
mysteries of flight. This important duty devolves exclusively upon the
male parent.
The eggs are oval in form, of a dark emerald green color, very highly
polished, and measure .97 of an inch in length, and .68 in width. There
is small chance of confounding this with any other American bird's
eggs--certainly after a specimen has been once seen. Dr. Abbott, as
quoted by Ernest Ingersoll, once discovered a nest, at Trenton, N. J.,
that contained purely white eggs, which hatched in due time into perfect
young. Similar instances are known in the case of other species laying
dark eggs, where one or two white examples have been found among others
of the normal color in the same nest-complement. But a single brood
is positively known to be raised, although cases have come under
our observation of nests with fresh eggs as late as the 15th of
August--possibly the work of birds whose early efforts had been
frustrated by enemies, or by some accident.
[Illustration: 048]
Plate IV.--ICTERUS SPURIUS, Bonaparte.--Orchard Oriole.
|The Orchard Oriole is quite abundant throughout most of the United
States, from the Atlantic to the Missouri Valley, and on the southwest
to the valley of the Rio Grande. Individuals have been met with by Mr.
J. A. Allen as far west as the base of the Rocky Mountains, in Colorado,
the extreme limit of its western range. It is probable that it breeds
throughout the entire area of its distribution--sparingly, however, in
New England, according to eminent authority; but quite freely in the
Central States, from New York to South Carolina, and thence south-west
to Texas.
The period of its arrival in the United States from the genial clime
of Guatemala, where it winters, has been fixed by Mr. Dresser, who has
carefully studied its nesting-habits in Texas, as early as the first or
second week of April. But, farther north, its presence is not observed
before the last week of April, or the beginning of May.
Unlike the Warblers and Thrushes, which prefer secluded localities, the
subject of our sketch delights in cultivated grounds, particularly
where the apple and the pear abound. Here it takes up its quarters,
accomplishes the object of its mission, and thence retires to its
distant winter-home. Occasionally, a few individuals are to be found in
waste grounds, dense thickets, or along the borders of woods, but such
cases are exceptional, and conditioned only by the close proximity of
some time-honored orchard.
Mating does not occur until the 10th of May, more than two weeks after
the advent of the sexes. But from the first, the male, who precedes his
partner by some two or three days, may be heard in the early morning,
and quite as frequently at the close of the day, from the tall
tree-tops, chanting his wanton rhapsodies, for a half-hour at a time,
utterly unmindful of passers-by. His roundelay, which is undoubtedly the
free and happy expression of a heart actuated by the generous impulses
of love, though composed of rather shrill and sprightly notes, and
uttered with considerable agitation, is quite as pleasing as that of
his nearest kin, the Baltimore Oriole. Clear, distinct and resonant, it
thrills the air around, and is at last borne to the ears of some lonely
female, tired with travel, and unblest by a partner. The life of the
Orchard Oriole seems to be one of joyous song. Although, fond of
a dainty tid-bit, in the form of a juicy worm, he is not given to
gormandizing; he only eats from sheer necessity; for, after having
satisfied the demands of Nature, he resumes his soul-stirring strains,
to the delight of man and bird.
The sexes having come together in a wise and business-like way, with
little or none of the bluster that is customary on such occasions, a
conference ensues, which results in a temporary separation for mutual
good; one bird going in one direction, and the other in an entirely
opposite course. The selection of a suitable spot for a home is the
_vera causa_ of this divergence. This is evidently a labor of little
moment, as, ordinarily, but a day or two is thus spent. It must not
be inferred, however, that the birds are not particular as to place. A
large experience has convinced us that great care and deliberation are
then exercised. Many a tree is visited, and often the same tree again
and again, before a decision is reached; and when at last a suitable
site has been chosen, the happy pair set to work with praiseworthy
diligence to construct a home.
As previously remarked, an apple- or a pear-tree is generally chosen for
nesting purposes. This is especially the case, as far as we are able to
ascertain, in the Central and Western States; but in Texas, the nest is
suspended from the upper branches of a mesquite-tree. In the North,
the common red maple, and several species of coniferous trees, are
occasionally chosen, from some peculiar advantages which they possess.
A nest in the writer's collection, which was built in the summit of a
common swamp maple, occupies a very anomalous position. It is placed
within a crotch formed by four nearly upright, slightly divergent
branches, and is secured by long, flexible grasses from the nest,
wrapped tightly around the twigs. Another specimen, from Germantown,
Pa., is made to dangle from the end of a pine-branch. A peculiarity
about the latter nest is the strained position which the four branches
to which it is fastened are made to assume. The main twig, which is also
the thickest (being about three-fourths of an inch in diameter) shows
evidence of having been forced from a horizontal position to one that
is almost vertical. The latter is really the best authenticated case we
have seen of the truly pensile style of nest. In most instances these
structures are but partially suspended, being supported from beneath by
projecting branches.
In five or six days from the time of the assumption of matrimonial
relations, the nest is started, and through the united efforts of both
birds for the period of a week, is brought to completion. Although
nidification usually commences about the 20th of May, from some
inexplicable cause or other, this essential business is often deferred
until the middle of June and, occasionally, as late as the beginning of
August. But in the latter case, the birds are undoubtedly prevented by
varions accidents from carrying out their designs earlier in the season.
In the building of a home, either the male collects the materials, and
the female weaves them into a nest, or the converse is the case.
There is little variety noticeable in the materials that compose
the nest. The generality of domiciles which we have seen from Texas,
Georgia, Florida, New Jersey, Pennsylvania, and several of the Western
States, have no lining, but are entirely constituted of one substance--a
flexible kind of grass or reed. In a few cases we have discovered a
slight lining of vegetable wool, doubtless plucked from the young and
developing fronds of various species of ferns. Bits of yarn, down of
seeds, and animal wool, have been mentioned by various observers as
occasional linings.
Such is the homogeneity of its texture, that once seen and recognized,
it can never be forgotten or confounded. A nest from Texas is the exact
counterpart of a similar structure from Pennsylvania, or of one from
Michigan. The abundance of the particular species of grass out of which
these birds construct their homes, and the facility with which it is
obtainable in localities remote from each other, conspire to produce the
resemblances which are found to exist.
Plate IV exhibits a nest of this species which was obtained in the
vicinity of Germantown, Pa., during the summer of 1880. It was suspended
from the branches of a pear-tree, in the manner shown in the drawing, at
an elevation of forty feet from the ground. It is built exteriorly of
a peculiar kind of long, tough and flexible grass, which is common
in Pennsylvania. The material is woven through and through in a very
wonderful manner, and with as much neatness and intricacy as if actually
done by a needle. It is hemispherical in shape, and open at the top. The
external diameter is four inches, and height two and a half inches;
the cavity is two and a half inches wide, and two and three-quarters in
depth. The color of the outside is yellow, while that of the inside is a
deep brownish-red.
Another specimen which the writer possesses from the same locality, is
built of the same material, more highly colored interiorly, but less so
exteriorly. It is pouch-shaped, and measures two and a half inches in
internal diameter, and four and a half inches in depth. The length is
five inches, and the external diameter three inches. When in position,
this nest was so placed that the short spurs of the pear upon which it
was built, with their beautiful green wreaths of leaves, met and roofed
it over, thus constituting a natural covering for the protection of the
young during the prevalence of inclement weather.
Dr. Brewer describes a nest taken by Mr. Brandigee in Berlin, Conn. This
structure was elaborately and skilfully woven of long green blades of
grass, lined on the inside with bits of yarn, animal wool, and a woolly
substance of purely vegetable origin. In external diameter and height it
measured four inches; in depth, three inches, and in internal diameter
three and a half inches--being widest in the middle. Specimens,
similarly colored, have been frequently observed in Pennsylvania.
By far the most remarkable structure which we have seen is the one we
are about to describe. This domicile was built in a red or swamp maple,
at an elevation of nearly thirty feet from the ground. It is a double
nest, composed entirely of long, flexible, yellow grasses, and securely
fastened between three nearly vertical branches, in a linear direction.
The main nest is inversely sub-conical, four inches high, with an
external diameter of three and a half inches in the middle, and four at
the top. The diameter of the cavity is three inches, and the depth
two and three-fourths inches. The smaller is joined to the first by a
continuation of the grasses of the latter, is somewhat similarly shaped,
but less compact in structure. The height is one and three-fourths
inches, external diameter in the long direction three and one-fourth
inches, and in the short, but two inches. The depth of the cavity is one
and three-fourths inches, and the width, one and a half inches. In one
side there is a circular hole one inch in diameter. Various opinions
have been ventured as to the object of this additional structure. Some
have contended that it was never intended for occupancy or ornament, but
is simply a fabric which the authors have failed to complete. But its
completeness and finish operate against such a theory. The writer, as
well as others who have witnessed this curious specimen of mechanism,
are convinced that it was erected for a special purpose--namely, the
accommodation of either parent while the other is sitting. The opening
alluded to, served for the head of the nonsitting bird, who, from his
position, looking away from the main building, could detect the approach
of enemies, like a sentry upon an outpost.
The nest being completed, on the following day the female begins to
deposit her complement of three or four eggs, at the rate of one egg
daily. Incubation now ensues, sometimes on the day of the last deposit,
but generally on the morrow. This duty lasts from fourteen to fifteen
days, and is wholly the work of the female. While she is thus occupied,
the male stands guard over the nest, or acts the part of a dutiful and
affectionate husband, by providing her with the necessary food. Should
their home be disturbed by feathered assailants, or by man, the female
leaves the nest, and by loud cries and menacing gestures, seeks, with
the assistance of her partner, to drive off the intruders. Often the
attack is carried on with a boldness and determination that challenge
admiration.
The love for offspring is very intense, and manifests itself in
unwearied devotion, and the tenderest solicitude. From early morn until
dusk, one parent or the other is constantly on the go for appropriate
articles of fare. Usually but one is absent at a time on this important
business. But the demands for food are so pressing, that both are
sometimes compelled to leave home, but only for a short time, and then
never beyond seeing distance of the nest. At first the young are fed
upon smooth caterpillars, aphides, spiders, ants, butterflies,
and dipterous insects; but as they mature, small beetles and other
hard-shelled articulates are added to their varied and extensive _menu_.
At the age of fifteen days, they quit the nest, receive instructions
in ærial navigation under the tutorage of the paternal head, and in ten
days more, are prepared to shift for themselves.
One peculiarity of this species must have struck the attention of every
careful observer of its habits; that is, its remarkable sociability.
Audubon cites a case where no less than nine pairs were found breeding
in the same enclosure. We have known instances where as many as five
nests, all occupied, were crowded in the same orchard, within a short
distance of each other. The most perfect good feeling and harmony
prevailed in this little colony, the birds mingling together with the
freedom and ease of inhabitants of the best regulated human communities.
The eggs are oblong-oval in form, pointed at one extremity, and marked
with pale purple blotches and a few deep dark purplish-brown dashes upon
a light bluish-white background. Specimens from Washington measure .85
by .62 of an inch; from New Mexico, .79 by .54; and from Pennsylvania, .88
by .58.

Plate V.--TYRANNUS CAROLINENSIS, Baird.--Kingbird.
|The Kingbird, or Bee Martin, has an extensive range, being found during
the summer throughout the continent of North America, from Texas and
Florida in the south, as far as the 57th parallel of north latitude.
Westward, north of the 44th parallel, it ranges from the Atlantic
seaboard to Oregon and Washington on the shores of the Pacific.
Its arrival in the United States from Mexico, Central and South America,
and tropical Cuba, where it winters, generally occurs during the
early part of April. Having taken the step, the birds are not long in
spreading themselves over their immense breeding-grounds, which have
been found to be co-extensive with the whole territory over which they
range. They reach the Middle Atlantic States from the 20th of April to
the first of May; the New England, from the first to the 10th of the
latter month, and their more northern habitats, not later than the 15th.
Careful observations, carried through a series of years, have convinced
us that the appearance of the males always antedates that of the females
by a week or ten days. Their advent is unheralded by song, or noisy
demonstration, and is as mysterious as their departure. Our knowledge
of the fact is mainly furnished by the eye, and not by the ear, which is
ordinarily the first organ that apprises us thereof.
Like most of its kin, the Kingbird is not gifted with a fine voice. When
it does essay a madrigal, its shrill, unmusical syllables are anything
but pleasing and welcome to the cultivated ear. It may be otherwise with
beings of its own special class. At all events, his song, if such it
can be truly called, has the anticipated effect--namely, that of
calling from her wanderings, the partner, whose presence he is anxiously
awaiting in his shady retreat.
Unblessed with the talent of producing sweet and soul-inspiring music,
Nature has made amends for her seeming neglect by endowing him with
certain mental and spiritual qualities which amply compensate for the
want of a melodious voice. A noble, self-sacrificing nature, and a
courageous but affectionate disposition, are traits of character which
our little friend possesses in a remarkable degree.
Aware of these high qualities, the female, never unduly coy, but
innocent, arch and simple, seeks rather than shuns the society of her
suitor, almost as soon as she has reached his whereabouts, and proudly
but courteously receives his attentions, which, without any show or
pretension, she generously reciprocates by consenting to become his
companion and helpmeet. Consequently, the season of courtship is
comparatively brief.
Mating being accomplished, the newly-made couple, without much ado, and
with but little waste of time, start off in quest of a suitable spot
for a nest. This appears to be a difficult matter to settle. The
pasture-grounds and waste places for which they have all along
manifested a strong predilection, are deserted for the more congenial
situations to be found about the home of man. Orchards of pear- and
apple-trees, or an isolated pear-tree in close proximity to a human
dwelling, are now visited. When the former, tree after tree is examined,
and the particular advantages of each discussed, before one is found
which answers all the requirements. These examinations often continue
for a fortnight. The female seems to be the controlling spirit in these
transactions.
The nest is generally placed between the forked branches of a pear-tree,
although the apple, cherry, osage orange, oak, cottonwood and tulip-tree
are sometimes employed for this purpose. Why the pear should be
preferred in certain localities above all other trees, it is difficult
to divine, unless the density of its foliage, and the short spine-like
twigs with which it is armed, afford security from the attacks of
rapacious birds and mischief-loving boys. Mostly the birds select for
building purposes the topmost boughs where the densest foliage abounds,
although instances are known to us, through actual observation, where
such structures have been found but five feet from the ground. Again,
nests have been met with on the borders of deep forests, in situations
remote from man, which fact seems to point to the conclusion that the
habit of building in orchards has been acquired since the peopling
of this country by human beings. The fondness of the Kingbird for the
little honey-bee, whose hives are generally placed contiguous to human
dwellings, has, doubtless, through the desire to be near such articles
of luxury, prompted the change of habitat. This species, like one of its
near congeners, occasionally builds upon the timbers of a bridge. Dr.
Brewer mentions a case which came under his observation in the summer
of 1851. While the doctor was passing over a bridge near the village of
Aylesford, N. S., he was startled to see an individual of this species
fly from a nest which was built on the projecting end of one of the
planks of which the bridge was composed. "So remarkably exposed a
position, open to view and on a level with and within a few feet of
the highway," says he, "must be quite unusual." One fact which the same
distinguished writer mentions, showing that the Kingbird, during the
breeding-season, is not always the same ugly, pugnacious little creature
which is claimed for him, must not be omitted in this connection. The
circumstance to which we refer, occurred in the summer of 1871. A pair
of these birds had built a nest in an apple-tree, near the doctor's
residence and within four feet of the nest of the Baltimore Oriole, and
not more than eight or ten feet from the abode of a couple of Robins,
all in the same tree. These three pairs were on evident terms of
friendship and good-will. The male Kingbird, from the topmost bough,
kept a vigilant lookout for danger, and seemed to have all under his
special care, but manifested not the slightest disposition to molest or
annoy.
Few species are more careless in the selection of nesting materials.
Almost anything of the proper length and requisite degree of flexibility
is utilized. Herbaceous stems, leaves of deciduous trees, strips of the
inner bark of the flax, lichens, weeds, wrapping string, carpet rags,
patches of cotton or wool, are a few of the many articles which are
found on the outside; while slender grasses, fibres of bark, fine
rootlets and horse-hairs constitute the inner arrangement.
A typical structure before us is rather loosely built exteriorly, but
increases in compactness towards the interior, where the materials are
more closely intermingled. The frame-work of this nest is composed of
herbaceous stems, chiefly of the wheat and pigweed, large quantities of
fibrous bark of a white, satiny lustre, and leaves of the oak, apple,
pear, etc. The inside is formed of fine grasses, quite artistically and
intricately laid in position. The cavity is beautifully symmetrical, and
measures three inches in width, and two and a half in depth. The outside
is five inches at the base, but contracts to four and a half at the
mouth. The height is about four inches. This nest was obtained in the
neighborhood of Chestnut Hill, Pa., June 15th, 1872.
Another structure which the writer obtained in the same locality, only a
few yards distant from the foregoing, differs slightly from it in form,
but largely in composition. It is built of compressed stems of wheat,
numerous and rather large scraps of printed paper, a few herbaceous
plants, all closely compacted and curiously intermingled. Within, there
is an inner fabric, secured to the former in a neat and substantial
manner, and composed of dark stems and leaves of various species of
grass, besides a small quantity of fine roots. The cavity is less
regular than that of the other, and conspicuously shallow. It measures
three inches in diameter and two in depth. The basal diameter is five
inches, which is nearly the width at the mouth. The vertical thickness
is three and a half inches.
The Plate represents a very beautiful nest which was obtained in
Southern New Jersey, in the summer of 1879. It was placed upon a
cherry-branch, as shown in the drawing, at an elevation of fifteen feet
from the ground. The outside consists of fine lichens, stems of grasses,
wrapping string, roots, tassels of the oak and chestnut, and some
mosses; the inside, of fine lichens, dried catkins of the oak, but
largely of slender stems and rootlets. The external diameter is four and
a half inches, and the thickness about one and three-fourths. The cavity
is three inches wide, and one and a half inches deep. In the engraving
it is shown the natural size.
Before drawing this part of our subject to a close, we cannot permit
the occasion to pass without giving a brief description of one more nest
which was obtained in June, 1880. It was placed upon the horizontal limb
of an apple-tree, at an elevation of about ten feet from the ground. The
peculiarity of this structure is the large number of carpet rags which
depend therefrom. In most cases they extend from ten to fourteen inches
beyond its lower border, thus contrasting very markedly with the dark
stems and rootlets that make up the bulk of the exterior. Was this
arrangement the result of blind chance, or were the rags placed there
for some special purpose?
The building of a home occupies the birds from four to five days. Did
the builders work continuously at it from sunrise to sunset, the period
of nidification would be considerably shortened. But such is not the
ease. They seem to have no regular hours for labor, but only work as
it suits their convenience. The duty of the male is to collect the
materials; that of the female, to arrange them in suitable places. The
nest being completed, scarcely a day passes before the first deposit is
made. Subsequent deposits are made on consecutive days until the full
complement is reached, when the female on the day following the last
extrusion, takes the nest, and continues thereon, with brief intervals
of intermission, for a period of thirteen or fourteen days, when her
labors are repaid by the appearance of a nest-full of tiny fledglings.
While she is thus occupied, the male acts the part of a dutiful and
faithful husband, guarding her from danger, and supplying her with the
choicest and most savory articles of food. When not foraging, he may be
seen upon the topmost bough of the tree upon which the nest is placed,
directly above his mate, on the constant lookout for danger. Should an
enemy approach, he immediately gives vent to his displeasure by a few
shrill twitterings, elevates his crest, and then gives chase to the
intruder, whom he pursues for a considerable distance, all the while
darting at him from different positions, and inflicting the severest
punishment, in order to teach him the folly of trespassing. Owls,
Eagles, Crows, Grakles, Jays, and even the common barnyard Hen, are made
to feel the force of his vengeance; but his most implacable enemy is the
Purple Martin.
The young are objects of more than ordinary parental solicitude. The
most endearing attentions are lavished upon them, and no efforts are
spared to render them comfortable and happy. Caterpillars, flies, and
other equally tender insects, are brought in great quantities, during
the first few days of their existence, to satisfy the demands of their
greedy appetites; but as they become larger, beetles and grasshoppers
are added to their dietary. When fourteen days old, they quit the nest,
but still remain under home influences for a fortnight later, when they
are allowed to shift for themselves.
In many particulars the eggs of this species resemble those of the
Arkansas Flycatcher, but differ mainly in their somewhat larger
size, and more pointed form. They are oval in shape, white in
ground-color--except when fresh, when they show a roseate tinge--and
beautifully spotted with brown and reddish-brown blotches and markings,
which are confluent about the larger extremity in some, and irregularly
scattered over the surface in others. They measure from 1.02 to .87 of
an inch in length, and from .75 to .72 in width. Specimens from different
parts of the country have been examined, and all, without exception,
bear a very close resemblance to each other, scarcely differing more
than do eggs of the same clutch.

Plate VI.--AGELAIUS PHOENICEUS, Vieillot.--Redwing Blackbird.
|The Redwing Blackbird is found throughout North America, from ocean to
ocean, and westward to the 57th parallel. From Texas and Florida to
the plains of the Saskatchewan, wherever found, it breeds more or less
abundantly.
During the winter they congregate in large parties in Southern Virginia,
the Carolinas, and all the Gulf States, especially near the sea-coast
and among old fields of rice and grain. Occasionally, small flocks
are found during the same season about stables and hay-stacks, in the
vicinity of Vancouver. But in the Eastern, Middle, Western and Central
sections, they are chiefly migrants.
Early in March these large assemblies break up, a part separating
in pairs and remaining among the Southern swamps, while the greater
portion, the males leading the way, direct their movements northward.
Later in April they have re-established themselves in their favorite and
accustomed haunts.
On their arrival, the males consort together in high open fields, where
their songs may be heard, at regular intervals, from morning until
night. At this time they are rather suspicious, and can be approached
only by the exercise of great caution. But when the females make
their appearance, their attention becomes so absorbed, that they are
apparently oblivious of events transpiring around them. The presence of
the latter is the signal for redoubled vigor in the line of music.
From bush and tree, from ground and fence-rail, and from almost every
available place, in loud, clear and resonant notes, is heard their
strange, unmistakable melody, each bird striving to outsing his
companions. Ever and anon a half-dozen voices may be heard at the same
time, producing a perfect medley of sounds, enough to "split the ears of
the very groundlings." The males seem never to weary of singing. It is a
remarkable and well-authenticated fact, that during the breeding-period,
and even late in September when preparing to migrate, the same sweet but
pensive strains are heard.
Nearly three weeks have expired since the advent of the Redwing, and
still the sexes remain unmated. This cannot long continue. Already a
change is manifest. The males are more musical, while, on the other
hand, a spirit of restlessness pervades the females. The latter are now
no longer given to feeding as before, but cease from their labors, and
bend listening ears to the gushing notes of love which swell around.
Enraptured, impressed, they eventually emerge from their hiding-places,
select their partners, and hie away to more congenial scenes.
The period of mating is unusually short, and unmarked by any special
peculiarities. It generally occurs about the 20th of April, but seldom
later than the beginning of May. The chief concern of the newly-wedded
pair now seems to be the selection of a building-spot. This is a matter
of importance, and, with most species, is attended with considerable
difficulty. Not so in the present instance. The birds repair to
accustomed sites, and there, amid the small bushes and tussocks which
abound, prepare their houses.
Nest-making commences in the Middle Atlantic States between the 25th of
April and the 1st of May; in New England, about the 1st of June, but not
before the middle of this month, in more northern regions. The nest is
usually placed in a cluster of reeds, or in the tops of small bushes
alongside of streams of water. Occasionally, small trees and fields of
timothy are made the recipients of these marks of attention, and, in
rare instances, the bare ground is made subservient to this purpose.
Almost every ornithologist who has paid any attention to field-work
has observed nests in their ordinary positions upon small hushes, or in
bunches of swamp grass, but few, we opine, have met with them elsewhere.
Mr. Maynard, as stated by Dr. Brewer, seems to have been the first to
notice this change. While exploring an island in the marshes of Essex
River, he found a number of nests in trees at an elevation of twenty
feet from the ground. One of these structures, which was purse-shaped,
was composed entirely of eel grass, and placed upon a sapling, at a
height of fourteen feet.
High grounds are seldom chosen for nidificating purposes, for the
obvious reason that they offer poor facilities for food-collection; the
aquatic larvæ, may-flies, dragon-flies, and mosquitoes, which constitute
a conspicuous part of the diet of these birds, being only found in
marshy situations. Even here a preference is manifested for certain
positions. Small bushes along the borders of streams, from the two-fold
advantages which they possess, are almost wholly adopted in some
localities. Being convenient to appropriate food-stuffs, they are placed
beyond the reach of snakes, particularly water snakes, which have a
decided partiality for young birds.
Having selected a building-spot, the pair proceed with all possible
dispatch to construct a home. This requires the joint labor of the
sexes, during the early mornings and evenings, for a period of about
five days. The articles of composition are chiefly collected by the
male, while the female performs the more difficult operation of putting
them in position. Considerable differences are often noticeable in
these structures. Those placed upon bushes are, as a general thing,
more symmetrical and compact than those found in clumps of grasses, and
differ still further in being-plastered with mud on the outside, which
adds to their durability; while, on the other hand, nests enclosed by
tall overarching grasses, have a looseness of arrangement that will
scarcely bear manipulation. But where the nest is placed in fields of
timothy and clover, there is evidence of great pains having been taken
in its construction.
Having finished their domicile, generally on the following day, but
sometimes not for nearly a week afterwards, as is the case when mud and
other damp substances have been used in building, the female begins to
deposit her eggs, at the rate of one a day, until the full number of
five has been laid. Incubation follows on the day of the last deposit,
and continues for fifteen days. This business devolves wholly upon the
female. While she is thus engaged, the male is not idle, but stands
guard over the nest, or ventures off in quest of food for himself and
companion. Should the nest be assailed, both parents seek, by the most
piteous cries and remonstrances, to drive, off the offending party. In
case of pillage, they keenly feel the injustice, and for several days
bewail their misfortune. But they soon recover their usual spirits,
and prepare to remedy the disaster. So tenacious are they of a chosen
locality, that the same pair has been known to build as many as three
nests in the same bush, after having been robbed twice.
The parents show the most intense affection for their progeny. Day after
day they watch over their helpless infancy with a devotion somewhat akin
to that which a human mother manifests toward her child. Their slightest
desire is a law, which is obeyed with cheerfulness and alacrity. When
food is in demand, they prove themselves to be willing providers, each
parent vying with the other in patience and fidelity. While one is
absent in quest of food, the other remains at home to protect them from
danger, the labor being accomplished by turns. Earthworms, caterpillars,
fresh-water larvæ, flies and mosquitoes constitute their earliest fare.
But later, beetles, butterflies, and various kinds of fruits help to
swell their hitherto very extensive dietary. When about fourteen days
old, the young leave the nest, but are not yet prepared to earn
their own living. This requires an additional period of twelve days.
Brood-raising being over, both young and old continue in the old haunts,
until near the time of departure, when they collect in small flocks, and
take up their southward-bound journey.
A typical nest of this species is somewhat irregular in shape, and
rather coarsely and rudely built. It is composed of stubble and broad
grasses variously intermingled, and lined with soft meadow grass. The
dimensions vary according to locality. Several nests before us, from New
Jersey, Pennsylvania, and the South and West, have an average external
diameter of five inches, and a height of three. The cavities, however,
are more uniform, and generally measure three inches in width, and
one and a half in depth. But when a nest is built in a bush, the outer
basketlike frame is carefully interwoven with, and strongly secured to,
adjacent twigs. Though somewhat rudely put together, it is nevertheless
firmly and compactly woven. The outer framework is usually made of
rushes, strong leaves of the iris, and, in some instances, of an
additional article apparently similar to mud. Within is packed a mass
of coarse materials, over which is placed a thick lining of grasses
and sedges. These nests, in the matter of size, differ from the former
chiefly in the particulars of length and thickness. The internal
dimensions offer no very striking exceptions.
The nest represented in the Plate is three-fourths of the natural size,
and was obtained by the writer in the summer of 1879, by purchase, from
Mr. Alexander M. Reynolds, of Philadelphia. It was built in a field of
grass, many of the stalks of which being wrought in its composition. In
figure it resembles an inverted cone, and is beautifully, symmetrically
and compactly put together. The outside is formed of grasses and rushes,
very neatly and intricately interwoven, and shows here and there a head
of dried pappus plucked from some species of hawkweed. The inside is
lined with sedges and fine blades of grass. As shown in the drawing, the
nest occupies a rather conspicuous position. This was not the case in
its natural location. Being found in the centre of a large field, it
is at once evident that the authors had spared no pains to make the
concealment as complete as possible. In height, this fabric measures
nine inches. Its external diameters above, below, and in the middle,
are, respectively, six, two, and four and a half inches. The width of
the cavity is three inches, and the depth three.
The eggs are oval in contour, of a light bluish ground-color, and are
marbled, blotched and streaked with light and dark purple, chiefly about
the greater extremity. In size, they vary considerably; the average
length of a large number of specimens from different regions being 1.01
inches, and breadth .76. In the Middle, New England and Western sections
of our country, this species is single-brooded; but further south,
three, and even a larger number of broods, are annually raised.
[Illustration: 072]
Plate VII.--TROCHILUS COLUBRIS, Linaeus.--Ruby-throated Humming-bird.
The Ruby-throated Humming Bird is found throughout Eastern North America
as far west as the Missouri Valley, and thence northward to the 57th
parallel. It breeds from Florida and Western Texas to the plains of the
Saskatchewan and the head-waters of the Elk River.
From its winter-quarters in Guatemala and Mexico, it takes up its line
of flight when the season has fairly opened, reaching our southern
frontiers late in March. Thence it slowly advances northward in its
migration, arriving in Upper Georgia about the 10th of April; in
Pennsylvania, from the last of April to the Middle of May, and in its
northern habitats, during the last of May, or the beginning of June.
For a brief season subsequent to arrival the sexes remain apart, and
seem only intent upon the procurement of food. This is especially the
case in the Middle Atlantic States where their habits have been very
closely observed. Here they make their appearance with the blossoms of
the horse-chestnut and tulip-tree, and may be seen at all hours of
the day, in fair weather, delving into flowers for honeyed sweets,
or probing their bosoms for the caitiffs within. In feeding, their
movements resemble those of the hawk-moths. Gracefully they suspend
themselves in mid-air before the opening flowers, ravish their hidden
treasures, and, with almost the speed of an arrow let fly from a bended
bow by some skilled archer, are off in an instant, possibly to more
delectable vineyards, or to some shady nook for rest and contemplation.
For agility and fleetness of motion the little Ruby-throat is certainly
unsurpassed by any of our smaller feathered species.
But things cannot long remain in this state. Their favorite flowers must
soon wither and decay, and with their timely death, must inevitably come
the disappearance of an easy and luxurious means of subsistence. The
tooth of appetite will then grow dull, and other thoughts and scenes
invite their attention. Experience has taught us that the falling of
the blossoms of the horse-chestnut and tulip-tree foretell the time of
mating.
This important business is performed without the least semblance of
show. The sexes tired, as it were, of the riotous and luxurious lives
they have been leading, come together by mutual agreement, and enter
into matrimonial relations. This being accomplished, they separate for a
brief period, and each proceeds to scour the country for miles around
in quest of a suitable tree in which to locate. When one is selected
by either bird, the other is summoned to the spot to talk over, in true
bird-language, the merits thereof. Should the parties differ as to the
advantageousness of the site, no quarrelling or bickering is indulged
in, but, in the most friendly manner, they separate, and renew the
search until one is found which gives satisfaction.
Having decided upon a locality, the birds are now ready to commence
building. This takes place between the first and the tenth of June in
the Middle States, about the tenth in New England, and as early as the
fourth in the Southern Atlantic and Gulf States. The situations chosen
vary considerably. Sometimes high, open woods are selected; again,
low, dense thickets; but, more frequently, an orchard close-by a human
dwelling, or an isolated tree in the midst of a lawn. Occasionally, the
birds have been known to build in trees along travel-worn thoroughfares.
A case in point came under our notice in the summer of 1872. While
returning home one day, we were surprised to see a female fly from her
nest in a maple-bough, only a few feet above our head. The nest was
immediately examined, and found to contain a pair of young birds. Not
wishing to disturb the happiness of the family, we permitted it to
remain intact. On visiting the spot a week or ten days afterward, it was
found to be empty, the birds either having matured and flown away, or
else had been killed by some ruthless invader. For several successive
years a nest was to be seen on the same tree and branch, but whether the
work of the same pair, we are unable to say.
That this species is not very particular as to the kind of tree in which
it builds, has been our experience, and we do not find any recorded
instance of disagreement. Dr. Brewer mentions but one kind of tree
in which it builds--the apple. In addition to it, we have found nests
saddled upon the pear, red-oak, white-oak, willow, red maple, sugar
maple, cottonwood, beech, pine, etc. In fine, almost any tree will
answer this purpose, as the generality of arboreous growths are more
or less favorable to the development of lichens. Several anomalous
positions, as on pine-cones and warty excrescences, have frequently been
met with in our ornithological rambles.
The nest is the result of the joint labor of both birds, who work with
unwearied perseverance and diligence until it is completed; the male
furnishing the raw material to be manipulated and adjusted by his
zealous partner. Occasionally, the latter assists her "liege lord" in
collecting and bringing in his burden.
In the matter of composition, there is but little difference in fabrics
from the most distant regions. Nests from Texas are exact counterparts
of those from Georgia; and these, again, resemble others from
Pennsylvania and Michigan. All we have seen are composed mainly of a
woolly substance of vegetable origin, plucked from the leaves of the
common mullein, or from the young and unexpanded leaves of the various
species of oak, immediately before their full development. This
substance, after being wrought into form and symmetry, is strengthened
on the outside by small woody fibres, or the webs of spiders. Over all
is placed a close and compact thatching of small lichens, a species of
Parmelia, glued thereon by the viscid saliva of the builders. On the
inside may be frequently observed a thin lining of white feathers; and,
on the outside, a few dried catkins. In dimensions, these nests usually
measure one and a half inches in external diameter, and nearly one and
three-fourths in height. The cavity is generally three-fourths of an inch
wide at the rim, and the same in depth. Specimens have been met with
which were but half an inch deep, and others which showed a much greater
depth, as well as external height.
The nest in the Plate is from Comal County, Texas, and was found upon
a beech-tree. It is composed almost entirely of vegetable wool from
the poplar and oak, and is lined with a few small white feathers.
Externally, there is a dense covering of bluish crustaceous lichens and
brownish oak-tassels, which are held in position by saliva and strands
of spider's silk. It was placed upon a branch at an elevation of twenty
feet above the ground. In height it measures one and three-fourth
inches; in external diameter, one and a half. The width of the cavity is
three-fourths of an inch, and the depth about a half.
A nest obtained in Lynn, Mass., in June, 1860, was saddled on a
horizontal branch of an apple-tree. It is woven of a soft woolly
material, fine in texture, silky in appearance, and of the purest white
color. Basally, it is strengthened with pieces of bark; and laterally,
with fine vegetable fibres. The whole exterior is beautifully covered
with a compact coating of lichens. It measures one and a half inches
in height, and two and one-fourth in external diameter. The cavity is
shallow, and is seven-tenths of an inch in depth, and one in width.
A very beautiful nest, as well as a marked deviation from the normal
form, as far as materials of composition are concerned, was discovered
in June, 1870, upon a branch of a red-oak which overhung a by-road, and
within a few feet of a woollen factory. Scattered in the neighborhood
was a lot of reddish shoddy, which had been discarded by the mill hands.
The birds, it is evident, were not slow in perceiving the use to which
this "waste" could be put. Accordingly they set to work, and, in a few
days, had constructed a beautiful nest, at a saving of much labor and
time. It might be thought there was a dearth of the usual materials, but
this was not so, as a careful survey of the grounds soon satisfied us.
Interiorly, this nest was entirely composed of this shoddy, while the
exterior was covered with the ordinary lichens fastened to the nest
proper by a few cobwebs and a secretion from the builders. In external
diameter, it measured one and three-fourths inches; in height, two
inches; in internal diameter, three-fourths of an inch, and nearly as
much in depth of cavity.
The nest being finished, which is the work of five or six days, but
a day or two elapse, and the female is ready to deposit her eggs. The
latter, to the number of two, are laid in as many consecutive days.
Incubation immediately ensues, and continues for a period of eight days.
Its duties devolve upon the female, who sits with commendable patience
until her task is accomplished. While thus employed, her mate stands
guard, or is abroad in quest of food. If any attempt is made to
interfere with the nest while he is on duty, the most menacing gestures
and loudest remonstrances are indulged in. Should these not have the
desired effect of frightening away the intruder, he darts at his foe
with wide, open bill, and endeavors to inflict summary punishment. He
is so persistent in these attacks that it is often very hard to beat him
off. The female, on the contrary, is of a more passive nature, quietly
keeping the nest, although not unmindful of the proceedings being
enacted, and only venturing therefrom when danger is imminent. These
assaults continue while the nest is endangered, and even for a short
time afterwards, when the birds retire to a neighboring tree to brood
over their mishaps, and consider what is best to be done.
The young are objects of special interest to the parents, who render
them every needed attention. When one is absent for food, the other
stays at home to protect them from danger. Their food consists of a
prepared mixture of nectar and soft insects, which they procure by
thrusting their bills into the mouths of their parents. It was formerly
supposed that this diet consisted entirely of the honey of flowers, but
this opinion of the ancients was not wholly a fallacy, since a portion
of nectar is taken with the insects, and supplies to the Humming-bird
that kind of nourishment which the larger insectivorous birds derive
from fruit. When eleven days old, these tiny creatures, in their
beautiful robes of green, quit the nest, but necessarily remain
under parental control a week longer, before they are able to support
themselves. By some inexplicable circumstance, the young do not
leave for their winter-homes until some time after their parents have
departed.
The eggs are beautifully elliptical in outline, and of a pure dull white
color. They measure .50 by .34 of an inch. Never more than a single brood
is raised annually. Nests with eggs have been taken as late as the 20th
of July, but these were doubtless laid by females whose early efforts
had been interfered with.

Plate VIII.--PIPILO ERYTHROPHTIIALMUS, Vieillot.--Towhee Bunting.
|The Towhee Bunting, or Ciieavink, has an extended distribution
throughout the eastern portions of the United States, ranging from
Florida and Georgia on the south-east to the Selkirk settlements on the
northwest, and westward to the border of the Great Plains, where it is
replaced by closely allied races. It breeds wherever found, certainly in
Georgia, and, doubtless, in Florida, although sparingly.
According to Wilson, it is found in the middle districts of Virginia,
and thence south to Florida, during the months of January, February
and March; but as the weather grows mild, and Nature begins to don her
livery of green, many forsake these haunts, and wing their flight
to distant localities; reaching the Middle Atlantic States about the
fifteenth of April, Massachusetts and Connecticut towards the last of
the month, Maine and New Hampshire early in May, and the North-western
States a little later.
In some regions the birds arrive singly, but retire in small flocks.
This is the case in the vicinity of Washington; whereas in Eastern
Pennsylvania, they are somewhat gregarious for a week or ten days after
their arrival, when they separate, and lead solitary lives. Their sole
object now is the acquirement of food. For this purpose they repair to
waste fields and damp thickets, or to small patches of underbrush
along frequented roads. Here their simple song may be heard during the
intervals of feeding, with scarce an intermission, from five o'clock
in the morning until eight in the evening, by the early or belated
pedestrian. In rain or in sunshine, or at noonday in the hottest weather
of the season, the woods resound therewith, or with that peculiar note
of complaint from which the species has received the name Chewink.
There is an expression of cheerfulness in these notes, though they are
not delivered with that enthusiasm which characterizes the songs of many
of our species. But music, like poetry, must be of a somewhat plaintive
nature, if it would take firm hold of the feelings.
After a period of three or four weeks mostly spent in feeding, the males
seem to tire of such a life, and seek to attract the attention of the
females. Perched on the lower branch of a tree, near the edge of a
wood, or 011 the summit of a small tree or tall bush in the midst of
a thicket, or hid from view by clusters of bushes, they may be heard
pouring forth, with all the fervor of their being, their strange
madrigals. At first, their efforts to captivate are unheeded. But
patiently and persistently the singing is kept up in a quiet, simple
manner, until their auditors become impressed, and modestly quit their
shady retreats to encourage the musicians by their presence. Having
gained this advantage, they follow it up, and in less than a week from
the time the first note was uttered, have mastered the situation. The
females wholly entranced, yield to the persuasions of their would-be
lords, and conjugal relations are entered into. This generally occurs
not later than the fifteenth of May. But the happy couple are not yet
ready to begin nest-building. They must needs celebrate the occasion
of their marriage. Accordingly, they set out on a wedding-trip, so to
speak, visiting adjoining lots and thickets, and enjoying the delights
and scenes around them. This continues for four or five days, when the
lovers, thoroughly surfeited, return and quietly settle down to prosy
life.
The erection of a home is now the absorbing topic of interest and
conversation. Where to build, and how, are matters that are agitating
their minds, and which seem, judging from the actions of the parties
interested, very difficult questions to adjust. After no inconsiderable
portion of time thus spent, and with little possibility of coming to any
decision, a separation ensues, and the country scoured for miles around.
Should a situation which seems eligible be discovered by either
party, the other, by a peculiar signal, is called to the spot, and the
advantages thereof carefully discussed. If satisfactory, it is accepted,
and building operations commenced. Otherwise, the search is commenced
anew, and continued until one is obtained which is mutually pleasing.
But where the birds are unmolested, the same localities are probably
selected on each return of the breeding-season. The situation generally
chosen is a small thicket with a dense growth of underbrush, or a high
piece of ground overrun by brambles, and dotted by patches of fern.
Latterly, nests have been frequently found in clumps of tall grass, in
fields once swampy in character.
In New England, the locality usually chosen is a low, dense woods,
thickets of briers and bushes near streams of water, or the "scrub,"
which is a low or bushy "growth" of trees, chiefly of oaks and birches,
occurring in dry, hilly lands once occupied by pines. In the extreme
northern limits of its range, dry uplands, near the edges of woods, or
high tracts covered with a. low brushwood, are used, rather than low or
moist grounds, as was the case in some sections at the time when
Wilson wrote. The love for such situations doubtless gave rise to the
appellation of "Swamp Robin," which is generally applied to this species
in Pennsylvania.
When placed within a thicket, or in the borders thereof, the nest is
either built in a depression of the ground, usually beneath a bunch
of grass, in a pile of old brush or fagots, or on a slight prominence
surrounded by tall, graceful ferns. Within a concavity, the structure
is made to project slightly above the margin thereof, and is artfully
concealed from the gaze of intruders by dry leaves. So completely is it
hidden, that all efforts to find it frequently prove unavailing.
The work of building is entered into with diligence and alacrity, each
bird collecting and adjusting the materials as it thinks best. While
thus engaged--which is usually from sunrise to sunset, allowing the
necessary time for foraging and rest--the architects seldom, if ever,
get at outs, but labor with a purpose, and in the best of spirits. The
time thus spent has never been known to exceed three days.
So little variation is manifested in these structures, that specimens
from the Southern States resemble those from the Eastern, Middle and
Western sections so closely, as to be readily identified by persons of
the least experience in such matters.
A typical nest is mainly composed of the leaves of deciduous trees,
twigs, grass and roots, 011 the outside, and is lined with the inner
fibres of the wild grape-vine, or with fine stems of grasses. The
drawing represents it as being constituted of the stems of grasses, with
a slight intermixture of leaves and roots, and as having a lining of
reddish-brown stems of the same. It measures four and a half inches in
extreme diameter, and two and a half in height. The internal diameter is
two and three-fourths inches, and the depth of cavity one and a half.
Oviposition commences on the day succeeding the completion of the nest,
and proceeds at the rate of one egg daily, until the entire complement
is deposited. Incubation closely, follows, usually a day or two after
the last egg is laid. This is undoubtedly the exclusive task of the
female for a period of thirteen days. Diligent and close watching has
failed to show that the male takes any direct part in this important
business. Although seemingly averse, or unaccustomed to this kind of
work, he does not fail to contribute his share to the success of
the undertaking. While his wife is engaged in sitting, he is an ever
watchful and cautious husband. Unlike many other species, he does not
make himself too conspicuous, but stations himself some distance from
the nest, for fear of revealing its whereabouts, and only ventures into
the neighborhood at certain regular periods, to receive the commands
of his patient little house-wife, or to administer to her bodily
wants. Though shy, these birds often seem saucy; and, while one person
complains of their chirruping to and starting his horse, another claims
that, 011 the discovery of their nest, they express their grief so
impudently as to arouse his indignation. But when the nest lias been
stumbled upon by some cruel oologist, and the female is compelled to
abandon it and seek safety in flight, the male does not even then
desert his hiding-place to come to her rescue. Everything is left to
her judgment, and well does she play her _role_ in the drama. By various
strategic movements, such as imitating the actions and cries of a
crippled bird, she decoys the inexperienced intruder to a remote
distance, when she flings off' the veil of hypocrisy, and quickly
disappears in the bushes. With the trained collector this _ruse_ hardly
succeeds, and the disappointed parent often beholds with profound sorrow
the discovery of her nest, and its destruction by ruthless hands.
When the young are hatched, they are watched over with jealous care, and
receive more than ordinary attention. Grubs, earthworms, plant-lice and
larvæ of butterflies, in immense numbers, are daily gleaned, and fed
to their hungry appetites. Such are their demands for food, during the
first week or ten days of existence, that the parents are kept extremely
busy in catering thereto. Occasionally, both are absent from home 011
this important business, but the rule seems to be for one parent to
keep a watch over it and its helpless inmates, while the other is thus
occupied.
At the age of thirteen or fourteen days, the young quit the nest, and
receive their first lessons in the mysteries of bird life; and, in
ten days more, are forced to shift for themselves, but are permitted,
however, to remain with the parents until the time of the autumnal
migration, when they help to form the small flocks which are seen flying
southward about the middle of October.
The eggs of this species are four in number, rounded-oval in shape,
and are covered over the entire surface with dots and blotches of
reddish-brown upon an obscure grayish, or reddish-white background. In
some specimens, these dots run into each other; and, in others, they are
distinct, being more profusely collected about the larger extremity.
The average measurement of a score of specimens from widely-separated
localities is .97 by .80 of an inch. Such is the resemblance which
obtains between these eggs and those of the Brown Thrush, that when
sets of both are placed together in a tray, the difference between
them would scarcely be apparent to a novice in such matters. It
remains for the keen and critical eye of the more advanced student to
point out the distinction, which consists in the paler and more
roseate tint of the Chewink's eggs, and the larger size of those of
the Thrasher. Wherever observed, these birds seem to be
single-brooded, although nests are sometimes found with young, in June
and August, which fact would seem to argue that occasionally more than
one brood is reared; but, generally, the first brood leaves the nest
too late for another to be brought out before the appearance of the
early frosts.
[Illustration: 088]
Plate IX.--PICUS PUBESCENS, Linaeus.--Downy Woodpecker.
|The Downy Woodpecker, or Lessee Sapsucker as it is called byway of
distinction, is a resident rather than a migratory species, and is known
to breed wherever it is found. Its area of distribution extends from
Lower Louisiana to Labrador, and from Texas northward through New Mexico
and the Indian Territory to the 58° of latitude. It is also quite common
in the maritime parts of Alaska, the Aleutian Islands excepted. Although
abundant east of the Rocky Mountains, and rather more numerous than its
nearest kin, the Larger Sapsucker, yet, owing to the smallness of its
size, it is not so well known outside of cultivated districts.
In the autumnal and winter months, these birds lead solitary lives. Go
where we will, then, we may here and there behold isolated individuals
busily probing the fissured bark of trees for the eggs and pupa of
insects. Even the mature forms meet with the same cruel treatment.
Though rarely observed in cultivated districts during these times, yet
a visit to the woods will reveal many a little fellow in dappled dress
arrayed, with or without a crown of red, wending his slow and labored
flight from tree to tree, or waking the clear echoes of rock and shady
glen with his shrill music and weird drumming.
But when balmy Spring returns, and releases the earth from the icy
fetters of the winter-god, and peoples our shade and fruit trees with
countless insect existences, then quits he the wild forest scenery, in
a measure, and betakes himself to our lawns and orchards. This is not
always the case. For in those lands where civilization has not planted,
but where Nature still reigns in her pristine glory, lie is the same
changeless creature as when first he greeted the vision of man.
'Tis now the social forces, freed from the frozen bonds of winter,
rejoice in new vitality. The sexes no longer shun each other as before,
but mingle in the most friendly manner. The male is the first to show
symptoms of change. He pursues his predatory exploits with less of his
characteristic zeal, and seeks to attract the attention of the gentler
sex. With this object in view, he arranges his toilet with scrupulous
nicety, and then goes forth to parade his beauties and grace before a
bevy of idle, listless females. Ever and anon, he varies his occupation,
by the rendition of a song. But his auditors seem either incapable of
appreciating his efforts to please, or else are too much concerned with
other matters to pay any real attention thereto.
Our little hero, not to be baffled, keeps up his courage, and with a
patience truly praiseworthy, continues his suit, till at last he reaches
the ear of some simple-minded female, when he pours forth, with all the
resistless eloquence of his being, the short but pleasing narrative of
his love.
Should his affection be requited as it deserves, the happy lovers,
without further ado, hie themselves away to sunny field or shady grove,
to enjoy a brief honey-moon, preparatory to entering upon the trying and
responsible duties of wedded life.
The getting of a wife is not always so easily accomplished. It is
generally attended with many trials and vicissitudes of fortune.
Sometimes when success seems ready to crown the efforts of an actor in
this part of life's drama, a rival comes upon the scene, and claims
the attention of the wooed. The most ridiculous antics now ensue, and
continue for hours together. The female becomes the most whimsical of
creatures, lavishing her caresses first upon one, and then upon the
other of her suitors. The jealousy of the contesting males now knows no
bounds, and only vents itself in long and fierce encounters. The female,
at last, comes to the rescue, desists from her meaningless flirtation,
and bestows the jewel of her affections upon her first lover. The combat
ceases, and the participants separate.
Occasionally, several pairs will meet by chance upon the same tree,
when similar scenes will be enacted by the jolly females, much to the
vexation of their respective suitors. These farces have been known to
last for nearly a week, but they seldom continue for a longer period
than two days.
Mating having taken place, which is usually the case during the
first week of May, never earlier except when the season is remarkably
advanced, the birds make ample amends for the time thus seemingly
frittered away, by the perseverance and diligence with which they
ransack the orchards and groves for a suitable tree in which to excavate
a nest.
The selection of a site is a matter of no little importance, the greater
part of a week being consumed in making the necessary reconnoissances.
These explorations commence early in the morning, and continue with but
few interruptions until the close of the day. They are never performed
singly, but always in pairs. One feature thereof strikes us as
peculiarly interesting, and as deserving of mention. It is the perfect
harmony and good-will which then prevail.
If a situation is discovered by one of the parties which is apparently
suitable, a conference is called, and the various advantages thereof
discussed. If mutually agreeable, further examinations cease, and
building operations are begun. In cultivated grounds, a decayed branch
of the apple or cherry is chosen for this purpose; but in more retired
situations, the maple, ash, elm or tulip-tree is given the preference.
In the Southern States, nest-building commences about the middle of
April; in the Middle Atlantic, seldom later than the fifteenth of May;
in New England, from the fifteenth of May to the tenth of June; and in
the extreme northerly portions of its habitat, about the fifteenth of
the latter month.
All things being in readiness, the male is the first to commence
operations. Stationing himself upon the spot which is to constitute the
doorway to his home, with claws imbedded in the wood to prevent from
falling, he digs the bark away in the form of a semi-circle. Then
reversing his position, he goes through the same difficult but trying
task, his little bill his only implement of execution, until he has
wrought a perfect circle. Continuing the labor, he delves away into the
soft or hardened interior, like a veritable Trojan, until an inch or
more of the wood has yielded to the blows of his small but powerful
chisel. Tired, at last, he resigns the work to his companion, and
settles himself upon a branch close-by to rest. Having recuperated his
exhausted energies, he starts off in quest of food, but to return in the
course of a half-hour to the relief of the female. Thus the work goes
on, day after day, with an industry and patience truly commendable,
until success crowns the undertaking.
The opening to the chamber is perfectly circular, and quite as accurate
as a skilful mechanic could make it with compasses. The cavity is first
directed downwards at an angle of forty degrees, for the space of five
inches, when it takes a perdendicular course for nearly ten inches
further, widening perceptibly at the bottom. Such is the capacity of
the latter that the sitting-bird is able to turn around therein with
considerable ease, but the external orifice is just large enough to
admit the bodies of herself and partner.
Few species are more careful to direct attention from the scene of their
labors than the subjects of our sketch. The chips produced during the
work of excavation are usually carried to some distance, so as to remove
all traces that might lead to detection. But howsoever clandestinely
they may act, and whatever precaution they may exercise, their home
does not always escape the keen eye of the experienced oologist, or the
sharpness and sagacity of the mischievous and insinuating little House
Wren--one of the most annoying enemies with which it has to contend.
Wilson gives an interesting account of the impudent coolness of this
bird, who coveting the neatly built home of this Woodpecker, and
powerless to construct such an apartment for herself, waits until
the Wookpeckers have finished their work, when she attacks them with
violence, and expels them from the nest which they have prepared with
so much pains. Another example is mentioned by the same distinguished
authority. In this instance, the Woodpeckers had commenced the work of
excavation in a cherry-tree, within a few yards of the house in which
he lived, and had made considerable progress, when they were assailed by
the Wrens, and compelled to withdraw. They then began a second nest in
a pear-tree, a few yards off' when after digging out a most complete
chamber, and laying one egg, they were once more attacked by the same
impertinent intruder, and finally forced to desert the place.
Having constructed their home, which is usually the work of a week,
the female, after a day of recreation and rest, begins the labor of
oviposition.
This continues for four or six days, the time being regulated by the
number of eggs which is to constitute a setting, but a single egg being
deposited daily. Incubation now follows, and is the exclusive task of
the female for nearly twelve days. The male, although he takes no
direct part in this business, is an important factor in the successful
accomplishment of the undertaking, as he, like an affectionate and
dutiful husband, supplies her with the necessary food. When not thus
occupied, he may be seen foraging the fields and woods, or perched upon
a twig in the calm enjoyment of ease and sober thought, He is seldom to
be observed in the immediate vicinity of the nest, save when carrying
food to his mate, or in times of great calamity. It has been affirmed by
Mr. Paine, of Randolph, Vermont, that the male occasionally constructs
a hole for himself close-by that of his mate, as he has taken males in
such apartments which were always unoccupied by eggs. He thinks that
they repair thither for shelter. Careful explorations for several years
have failed to show us that any such protection is practised in the
Middle States, nor do we find any record to substantiate this statement.
The young, when first hatched, are very helpless creatures, and require
the greatest care and attention from parental hands, so to speak.
Caterpillars, small moths, aphides and beetles constitute the bulk of
their fare, from the time they leave the egg until they are four weeks
old, when they quit the nest, to be instructed in the ways of the
outside world. For a fortnight the young birds rove in company, but
finally separate, each bird leading the life of a recluse.
The eggs of this species are nearly spherical, of a crystalline
whiteness, and measure .82 of an inch in length, and .71 in width.
Specimens from Eastern Texas and Southern Michigan differ but little,
if any, from others obtainable in New England and the Middle sections of
our country. In the Plate the eggs are shown in position, the wood being
cut away over the bottom of the chamber, to produce this result. The egg
in front, as well as the birds upon the branch, are three-fourths of the
natural size. The remaining eggs are in part concealed, and do not
show so fully. In the southern and middle portions of the range of this
Woodpecker, two broods are annually raised, one in June, and the other
in August, but further north seldom more than one.
[Illustration: 096]
Plate X.--VIREOSYLVIA OLIVACEUS, Bonaparte.--Red-eyed Vireo.
|The Red-eyed Vireo is quite an abundant species throughout Eastern
North America, ranging from Florida in a northeasterly direction to Nova
Scotia, thence northwesterly to Lake Winnipeg and Washington Territory,
and westerly to Ogden, Utah. Accidental specimens have been procured in
Greenland and England, but never more than a single individual in each
locality.
Many of these birds winter in Florida, and as specimens have been met
with in Central America, Cuba, Trinidad, and on the Isthmus of Panama,
it is highly probable that many betake themselves thither when the
period of breeding is over in their northern homes.
Early in March the latter enter the United States, possibly by way of
Texas and Florida, and wend their movements northward, reaching the
Middle States late in April; the New England, about the middle of May;
and the extreme northwest, a fortnight later.
Like all of its peculiar and characteristic genus, this species affects
a fondness for forests, or the summits of tall trees, but seldom
ventures upon the ground. It is, however, not wholly sylvan. At times
it may be found around dwellings, or along the shaded streets of
rural towns, in quest of the various insects which contribute to its
sustenance.
As it gleans among the tree-tops, the simple, pleasing and musical notes
of the male may be heard at somewhat regular intervals. So unsuspicious
and familiar is he then, that passers-by may come and go, and their
presence be unheeded.
During the hot and sultry hours of noon when other songsters have ceased
their warblings and foraging, and have slunk to the refreshing shades
for comfort and security, our little friend continues to pour forth
in loud, sonorous notes his peculiar
_te-te-tu'eah-we-ah-tweah-tweah-tweet_. Being the earliest of our vernal
choristers, he is also the most constant and untiring, and continues
to sing throughout the entire season. Even when about to depart for the
smiling scenes of his southern home, he thrills the air of woodland and
valley with impassioned song.
His tender and pathetic utterances, which resemble the melodious notes
of the Robin, but lacking their volume and power, are produced with so
much apparent animation, judging from their sound, as to be in striking;
contrast to the seeming indifference or unconsciousness of the plain
little vocalist who, while regaling the listener, appears all the while
to be bent upon the procurement of his daily food, which he pursues with
great ardor. But with the female the case is different. Although quite
as active a feeder as the male, yet there is apparent none of that
bustle and noise which characterize his movements. Her chief concern
seems to be the satisfaction of hunger, and a studious avoidance of the
male.
But as the days multiply, and insect life becomes more common, which is
generally the case about two weeks after their arrival, less anxiety
is felt on account of food; consequently, more time is left for the
development and play of the social forces. The sexes now begin to
manifest less reserve and coolness, and instead of shunning each other,
as was their wont, are brought more and more into friendly intercourse.
A week or ten days later, and the way is paved for the assumption of
matrimonial relations. In this movement, the male takes the lead. The
female, somewhat coy, at first listens to the wooings of her suitor at a
wary distance, but as time progresses, soon learns to regard him in the
light of a lover, throws off her restraint, and confidently advances
to receive his caresses. And thus events follow each other in rapid
succession until a union is effected.
Having mated, the happy pair, with no more delay than is absolutely
necessary, start off together in search of a nesting-place. This is a
matter that is easily accomplished, as almost any forest-tree of small
or medium height, answers the purpose. In some situations, the beech,
maple, sassafras and common laurel are in special demand. Why this is
so, it is impossible to divine.
High woods, with an abundance of small trees, are generally chosen.
Here, the nests are not often placed higher than five or six feet above
the ground. Sometimes, though rarely, they are found swinging from a
pendent bough, more than fifty feet high. Nidification seldom occurs in
compactly-built cities. Never more than a single instance has ever been
observed by us. This happened in the summer of 1876.
A site being chosen, building at once commences. This occurs in the
Middle States between the twelfth of May and the fifteenth of June;
in New England, about the first of the latter month; in Texas and
Louisiana, somewhat earlier; and in Nova Scotia, a trifle later. At Fort
Resolution, at the Cumberland House, and at Fort Simpson, nests and eggs
have been taken, but we are left in ignorance as to the time.
