birds, each collecting and adjusting its own materials. The time devoted
thereto varies from six to seven days, and is regulated by the industry
of the builders and the _condition_ of the weather. For this purpose
a bifurcated branch is first chosen. To this is attached, by means of
cobwebs, strips of bark, threads of moss, and the silk of caterpillars,
a delicate framework. This is mainly composed of bark, decayed
pine-wood, vegetable fibres, etc., held together by silk, and, possibly,
in a slight degree, by a gummy secretion supplied by the builders.
This structure is long, tenuous, open and narrow, presents a somewhat
collapsed appearance, and resembles, though remotely, the perfect
fabric. But it lacks shape and symmetry. To give it these essentials,
the birds construct an inner nest out of bits of paper, fragments of
hornets' nests, and strips of oak bark, which are so arranged as to
protrude through the interstices of the outer. It is now the duty of the
female, by a few bodily evolutions, to reduce the whole to form. This
accomplished, the labor of building is resumed, and a cozy lining,
composed of narrow strips of the inner bark of the wild grape-vine,
is added. Often white and black horse-hairs take the place of these
articles. That this species builds after the fashion described, is
proved by actual observation, and also by the finding of abandoned nests
which showed the outer, but not the inner arrangement.
The nest represented in the Plate came from Atlantic Co., N. J. It was
built between a forked branch of the common laurel. Externally, it is
composed of decayed wood, inner bark of plants, silk of caterpillars,
fragments of hornets' nests, cocoons of spiders, etc. Internally, there
is a thick lining of the inner bark of the wild grape-vine. The external
diameter is three and a half inches; internal, two and a half inches;
outside depth, two and a quarter, and inside, one and three-fourths
inches. A comparison with specimens from Texas, Michigan, Pennsylvania
and Massachusetts, shows marked similarities in structure and details of
composition.
In the collection of the Smithsonian Institution there is to be seen a
nest which was obtained by Mr. Kennicott at the Cumberland House, on
the Saskatchewan River. It is pensile, like all others, but is almost
exclusively built of pine-needles--a dry and hard material, difficult
of management in the construction of such a domicile. With these are
intermingled flax-like vegetable fibres, fine strips of bark, and
fragments of moss. Within is placed an inner nest composed of strips of
bark, pine leaves and fine, dry grasses. The external fabric is rather
loosely put together--an unusual feature--but the inner portion, in
the compactness and strength with which it was made, is in striking
contrast.
After the nest is finished, the female, on the ensuing day, and
occasionally not until the expiration of the third or fourth, commences
to lay her eggs, at the rate of one daily, until the entire complement
of three or four has been laid. Incubation follows closely, usually on
the day succeeding the last deposit, and continues for nearly eleven
days. This is not the exclusive task of the female, as the male
sometimes assists her. When the latter is not thus occupied, it is
seldom that he may be found in the vicinity, being absent either
designedly, or in search of food. Should the nest be approached at this
time, the female sits close, and seems to manifest neither timidity nor
alarm. We have often surprised her on the nest, and reached out our
hand to take her, when she would watch our actions very narrowly, as if
seeking to study our motives, but remaining perfectly motionless all the
while. A nearer approach was invariably followed by her sudden departure
therefrom. The bird would not wholly desert the nest, but demurely
station herself upon an adjoining twig, in order to watch our actions.
But with the male it is quite different.
Any attempt at disturbance or pillage is resented with spirit and
courage, especially when the nest contains young birds.
The home of this Vireo is often chosen by the Cowbird as a place of
deposit for her eggs. So singularly devoted to their alien guests do
these foster-parents become, that they nurture them very tenderly, even
to the neglect of their own offspring. A case is mentioned where three
of these parasitic eggs had been deposited in the nest of the Vireo
before any of her own. Without laying any, the female Vireo proceeded
to set upon and hatch the intruders. Another case is cited where two
Cowbird's eggs were laid alongside of two of the Vireo's. The latter
immediately stopped laying and proceeded to incubate. In each of these
cases it is evident that the female Vireo forewent her own maternal
instincts, and at once conformed to the new situation.
The young are objects of special parental interest. From the time
they are hatched, until the period of their leaving the nest to earn a
livelihood, they are watched over, and fed with the daintiest fare which
Nature affords. Caterpillars, diptera, plant-lice, small spiders and
berries, constitute their earliest diet; but as they increase in size
and strength, other articles of a coarser nature are added. At the age
of twelve days they vacate the nest, but continue under the watchful
eyes of their parents a week longer, when they are able to forage for
themselves.
The anxieties of brood-raising being over, both young and old, the
former in imitation of their parents, seek the tall tree-tops and glean
in company. Later, they come down from these lofty retreats to delve
among the grasses. Finally, as if disdaining too near an approach
to earth, they quickly forsake such groveling pursuits, and seek the
viburnum and dogwood bushes, where they find many a rich repast. Here
they remain until the last of September, or the beginning of October,
when cold weather and scarcity of food compel them to hunt warmer
climes.
The eggs of this Vireo vary considerably in size, according to locality;
the further south the smaller they are found. Specimens from Northern
Alabama have an average measurement of .77 of an inch by .52; from Nova
Scotia, .94 by .65; from Pennsylvania and Massachusetts, intermediate
localities, .82 by .56, and .83 by 62. The ground-color of all is a
clear crystal-white, and they are marked with spots and fine dots of
red-brown, which are chiefly found at the larger extremity. But a single
brood is raised, although nests with eggs have been taken early in July,
which must be attributed to birds whom accident or design had prevented
from obeying their natural instincts earlier.

Plate XI.--TRINGOIDES MACULARIUS, Gray.--Spotted Sandpiper.
|The Spotted Sandpiper has an extended and varied distribution
throughout North America. Unlike most of its allies, it breeds with
equal readiness wherever found, and is one of the best known and most
abundant of all its tribe.
From its winter-quarters in the Southern States, and also in the West
Indies and Central and South America, to Brazil, it takes up the line
of migration about the tenth of April, and gradually spreads itself over
nearly the whole country as far north as Labrador and Fort Yukon.
According to Mr. Trippe, it is the only species of its family that
resorts to the mountains of Colorado. Here, it arrives early in May, and
departs in September. All the larger streams, to an altitude of 8,000 or
9,000 feet, are visited, and, even, in some instances, the shores of the
lakes near the timber line.
On their first arrival, the banks of large rivers are frequented; but as
the season advances, many trace their way into the interior, along
the courses of our creeks and rivulets. Their sole object now is the
acquirement of food. For this purpose, a life of solitude is preferable
to any other. Although three or four individuals may frequently be
discovered together upon the same feeding-grounds, yet careful and
repeated observations have convinced us that this occurrence is merely
accidental, and not dictated by a desire for company. At such times, the
birds become so deeply absorbed in the business before them, that the
approach of human beings is unobserved, and the actors are only aroused
from the stolidity and indifference into which they have fallen, by
the crackling of a dead branch, or the dislodgment of a pebble from its
mooring. Conscious of impending danger, but never stopping to inquire
into the cause of the alarm, they seek safety in instant flight, and
repair to other scenes, at no great distance from the former, whore
they think to pursue their gastronomic occupation without fear of being
molested.
Such are the colors of this species, that the utmost harmony obtains
between them and the hues of surrounding objects. The keen eye of
the practised sportsman is often eluded thereby. Were it not for its
peculiar habit of wagging the tail, it would be a very difficult bird
to locate, especially when in a standing attitude; for whether thus
occupied, or running on the ground, or along the rails of a fence, or in
the water, this motion seems continual. Even the young, as soon as they
are released from the shell, are taught by instinct the same remarkable
movement.
Usually about the third week from the time of their first appearance,
but sometimes later, the sexes, grown corpulent from good feeding,
discard in a measure the "joys of the table," and seek each other's
society. From stilly bank of inland pond or stream, or where old Neptune
lashes in frenzied mood his solid flanks, their strange and simple call,
_peet-iveet, peet-weet_, may be heard in quick succession, louder,
and more distinct, than was their wont. Nor do the males alone indulge
therein; for the gentler sex oft join their lords in wanton rivalry.
Less whimsical than their aristocratic neighbors who affect the tall
tree-tops and shady bushes, the lady Sandpipers are more easily wooed
and won. Their ardent lovers have but to make their suits with due
obsequiousness, to receive the courted promises. A few more avowals of
love, and caresses, and the necessary reciprocations on the part of the
females, and the happy lovers having sealed their plighted pledges in a
bond of union, the respective parties journey off in search of suitable
places for establishing their homes. This event generally occurs about
the last of May, in some localities, but sometimes not earlier than
the second week of June, in others, and, perhaps, later in the extreme
northern limits of its habitat.
A period of three or four days being spent in examining the surrounding
country, the various parties soon settle upon localities. While some
prefer the borders of ponds and streams, or more retired and secluded
situations in the midst of forests, or a corn-field on elevated ground,
others, again, have a hankering for low, sandy islands, or marshes by
the sea-coast, or even the almost barren beach itself.
This part of the business being attended to, each female begins to
construct her nest. For this purpose she scratches a slight hollow in
the sandy earth, and proceeds to line it with a few pieces of straw,
or moss, or sea-weed, the nature of the materials depending upon the
_environment_. When the nest is placed in a corn-field, it is generally
built at the root of a hill of Indian corn, and is either lined with
straws, or mosses; when upon the seashore, various species of algae are
used.
Having finished her rather simple and hastily-constructed home, with as
little delay as possible the female commences to deposit her complement
of four eggs. This she does at the rate of one egg a day, in as many
consecutive days, taking due care to place them with the small ends
together in the middle of the nest.
The last egg deposited, the female, on the day thereafter, enters the
nest, and commences the duty of incubation. She is not necessarily a
very close sitter, especially when her nest is located in a sandy soil,
as the heated sand has doubtless much to do with the development of the
young. During inclement weather, protection is absolutely essential;
consequently, one bird or the other must occupy it, by turns, until the
necessity has passed.
While one is incubating, it does not appear that her partner is
compelled to play the part of a purveyor of food. Careful examinations
have never enabled us to detect the least evidence thereof. When either
party is tired, or is severely pressed by hunger, the other is summoned
to the spot, to receive the charge of affairs. Thus the business goes on
for eighteen weary days, when the happy parents are blessed with a jolly
little family.
The young are not the mere helpless creatures such as we have all along
been describing, but as active beings, for the age, as it is possible
to conceive of. Clad in silken robes of drab, with beautiful stripes
of black adown the back, they constitute a merry, rollicking group of
birdies. The world to them is a paradise of beauty, and a garden-spot
of pleasure. As soon as they leave the shell, they run with remarkable
speed, and otherwise exhibit a precocity which seems unnatural at that
period of life. Feeding, like running, is instinctive. It cannot be that
it is learned by imitation, any more than the exercise of the cursorial
powers can be said to be thus acquired.
Although much of the trouble and care which birds generally bestow upon
their offspring are thus saved to these fortunate parents, yet the
power to discriminate between bad and good food, has to be learned by
attention to the commands and actions of wiser heads. The young are not
slow to profit from parental suggestions and instruction, for we find
them, at the expiration of a fortnight, engaged in foraging with the
judgment and adroitness of adults.
Few species exhibit symptoms of greater distress than these Sandpipers
when their breeding-grounds are approached by human beings. The parents
resort to every conceivable stratagem in order to draw the intruders
away. Counterfeiting lameness, and fluttering along the ground with
seeming difficulty, are two of the most characteristic devices which
they practise for this purpose. But the appearance of a dog considerably
heightens the agitation. It is very interesting to watch the actions
of the female on such occasions. In order to lead him away from her
terrified young, she throws herself before him, flutters away in a
contrary direction, but always managing to keep out of the reach of
danger. This she continues for some time, until the animal has been
drawn to a considerable distance, when she throws off the garb of
dissimulation, and takes to flight, leaving her pursuer standing
stock-still and gazing with astonishment and disappointment at the
remarkable transformation which has just been effected. While all this
has been going on, the young have scurried away to places of shelter and
security, where they are afterwards joined by their beloved parent, glad
to have escaped so fearful a calamity, and grateful for such a happy
deliverance.
A more substantial proof of the affection of this female for its young
could hardly be imagined than that which Wilson gives on the authority
of Mr. William Bartram. The scene of action is described as being on the
river shore, and the occasion, the repeated attempts made by a ground
squirrel to capture two young birds which a parent was trying to
defend. In order to ward off the assaults of the squirrel, she had
thrown her two young behind her. At every attempt of the animal to
seize them by a circuitous sweep, she would raise her wings almost
perpendicularly, assume the most formidable expression of which she
was capable, rush forward upon the squirrel, who, intimidated by the
boldness of her manner, would beat a precipitate retreat. The enemy,
recovering from his defeat, would presently return, and renew the
attack, but to be ingloriously driven back as before. The young, as
though sensible of their perilous situation, would crowd together behind
their protector, and shift their position as she advanced or retreated.
This interesting scene continued for at least ten minutes, when
the strength of the poor parent was observed to flag. The squirrel
perceiving his advantage, became more daring, increased the frequency of
his assaults, and would have gained an easy victory had not Mr. Bartram
stepped forward from his hiding-place and drove him back to his hole,
and thus rescued the innocent.
The eggs of this species are usually abruptly pyriform, of a
yellowish-buff ground-color, and are marked with blotches and spots
of umber and sienna, which are collected chiefly about the greater
extremity, where they are sometimes confluent. Occasionally, some
specimens present a more elongated form, and others have the primary
color of a yellowish-drab tint, with the markings of a deeper shade.
The dimensions vary somewhat in a large collection from widely-separated
localities. The largest measure 1.41 by .99 of an inch, and the smallest
1.25 by .94. Considering the size of the bird, they seem to be out of
all proportion.
[Illustration: 112]
Plate XII.--SPIZELLA SOCIALIS, Bonaparte.--Chipping Sparrow.
|The Chipping Sparrow, so familiar to everybody, is not only one of
the most abundant, but also one of the most widely diffused of all our
species. It is found from the Atlantic to the Pacific in its two races,
and breeds from Georgia to Nova Scotia on our eastern seaboard, and
from Vera Cruz, Mexico, northward through Arizona, Utah and California.
Although obtained at different seasons of the year in all portions of
North America to Mexico, it is a strange and remarkable fact that its
breeding-grounds are not equally extensive.
Large numbers of these birds annually winter in the valley of the
Colorado, and thence doubtless spread themselves over the whole Pacific
region, as far north as Fort Resolution, on Great Slave Lake. In the
East they may be seen in companies of a hundred or more from October to
April through Northern Georgia and South Carolina, and possibly in the
Gulf States.
On the return of mild weather, which generally follows the vernal
equinox, these flocks forsake in a measure their winter homes, and
journey northward. Those from Northern Mexico pursue a northwesterly
course, reaching Arizona about the twenty-fourth of March, where a
part remain to breed; but the greater portion pass up the valley of the
Colorado, and after receiving fresh accessions to their number, continue
their migratory course until they have reached their destination. On the
other hand, our Eastern variety tarries longer in the South, and only
takes its departure when Nature, awakened from her winter sleep in our
Northern States, has begun to put on her charming robe of green. But
unlike its Western brother, it arrives in pairs, and never with the show
and pomp of a large army. The tardiness of vegetation, and the paucity
of insect life incident thereto, have doubtless much to do with the time
and manner of its coming. In the Middle States this event happens during
the last week of April, and in New England about the fifteenth, but the
birds do not seem to become very abundant in the latter section until
the beginning of May.
The Field and Song Sparrows, near relatives, are much earlier comers,
and are already in full song, making the groves and fields vocal with
praises, long before the Chippy has made his appearance. But when the
latter does arrive, we must look for his presence in our gardens and
orchards, rather than along the borders of thickets, where he commends
himself to our favor and esteem by his tameness and sociability. About
our doorsides he loves to glean his fare, and when an opportunity
offers, will often enter our houses during meal-times. So accustomed to
man does the species become, that individuals have been known to present
themselves regularly for food, as often as thrice a day, and even to
accept the same from human hands.
The male is so absorbed in feeding during the first ten days of his
stay that no attempt at singing is made. His only note then is a simple
_chip_, indicative of unrest. This is slowly uttered, and at somewhat
measured intervals. But later, he essays a song, and throughout the
month of roses, his unpretending ditty, which consists of a repetition
of the same sound, is kept up for hours together with scarce an
intermission. Though poor his reputation as a singer, yet individuals
have actually been known to sing, and very sweetly, too, but such cases
are wholly exceptional, _et lusus naturae_. Mr. Flagg, in speaking of
the male, says, "He seems to be the sentinel whom Nature has appointed
to watch for the first glimmerings of dawn, which he always faithfully
announces before any other bird is awake. Two or three strains from his
octave pipe are the signal for a general awaking of the birds, and
one by one they join the song, until the whole air resounds with an
harmonious medley of voices." Again, says the same happy writer, "His
continued trilling note is to the warbling band of morning musicians
which may be heard before sunrise during May and June like the octave
flute as heard in a grand concert of artificial instruments."
The singing of the males is the inauguration of a new era in bird-life.
The search for food no longer engrosses the attention as of yore,
but the all-absorbing passion of love. The sexes cease their solitary
wanderings. The females, moved by the touching appeals of the males,
leave their native haunts, and join their masculine companions. All is
now a scene of bustle and activity. The wooer and the wooed meet and
lavish upon each other the most endearing attentions. Happiness reigns
supreme. But the acme of felicity has not yet been reached. This is
brought about by degrees, and is only perfectly attained when conjugal
relationship is assumed.
In some parts of the country this important business is entered into as
early as the fifteenth of May, but in others it is necessarily deferred
until the succeeding month. The event is unattended by any peculiar
demonstrations of joy, and is mostly celebrated in a matter-of-fact,
businesslike way; the happy couple proceeding at once to an exploration
of the surrounding scenery for a suitable place in which to build a
home. This is a matter of little moment, as almost any small tree or
low bush is available for the purpose. The nest is never placed on the
ground, even in Arctic regions, where so many of our tree-builders
vary from this custom to nidificate on the ground. In the vicinity of
houses,' small trees, shrubbery and vines are utilized; but in pasture
grounds, and on the borders of small thickets, the common red-cedar is
chosen. Having selected a suitable site, both birds apply themselves to
the task of building for a period of four or five days, when a neat
and rather cosy structure is the result. Considerable variation is
discernible in the architecture of different individuals. Some nests are
rudely constructed, and rather loose and tenuous. Others have much of
periphery, but little of thickness and internal depth.
A typical nest is hemispherical, neatly but loosely built, and possesses
a cavity very symmetrical in contour. It is usually composed on the
outside, except in rare cases, of fine rootlets, and is lined with black
and white horse-hairs. In a beautiful domicile before us very few roots
are noticeable, the bulk of the fabric being composed of horse-hairs,
densely and compactly interwoven, and covered exteriorly with a few
fine twigs and lint. Other nests before us are built entirely of fine
rootlets. When such structures are found in bushes, and are well secured
and protected by enveloping leaves and twigs, a curious anomaly often
presents itself. A case of the kind came under our observation in
August, 1876. Since that time others have been met with. It is where the
nest, instead of occupying a nearly horizontal position, which is the
natural one, is placed at an angle of inclination, and bears in the
superior third a circular opening. What the object of this aperture can
be, it is impossible to say, as the bird could never be surprised while
on the nest. Possibly it was designed for the accommodation of the head
of the owner while the process of incubation was going on; or, it may
have been intended as a mode of ingress and egress, which opinion the
position of the nest and its surroundings would seem to warrant.
One of the most curious and exceptional nests which we have ever seen,
was obtained in the summer of 1870, in Northumberland Co., Pa. This
nest was built upon a small bush, at an elevation of two feet above the
ground. Externally, it is composed of dried plants, of an herbaceous
character, with seed vessels intact. Internally, there is a slight
lining of white horse-hairs. The diameter, on the outside, measures
nearly four inches, and the thickness three and a half inches. The
diameter of the cavity is three inches, and the depth nearly two. It
is a magnificent structure, closely and compactly woven, and exactly
hemispherical.
The drawing represents the usual style of nest. The position upon a
branch of the red-cedar is one that is frequently chosen. The outside is
mainly composed of fine roots of a reddish-brown color, and the inside
of an equal mixture of white and black horse-hairs. The dimensions are
as follows: External diameter, three inches; internal, two and a quarter
inches; depth inside, three-fourths, and outside, one and an eighth
inches.
The nest being finished, oviposition commences on the ensuing day, and
proceeds at the rate of one egg daily, until the entire number is laid.
This varies from three to five, even in the same locality. Incubation
commences on the day after the last deposit has been made, and continues
for a period of ten days. It is chiefly the duty of the female, although
the male occasionally lends his assistance by taking the nest. When
not thus occupied, he either polices the premises to guard against
intrusion, or is away in search of food. When with young both
birds become devoted parents, and evince the greatest anxiety and
consternation when their nest is disturbed.
Their actions at such times bespeak fear rather than courage. We have
never known them to assume the threatening attitude which characterizes
so many of our small species, nor seek to drive intruders away by sharp
scoldings and angry gesticulations. But knowing that resistance would
be useless, they quietly submit to circumstances, and repair to other
scenes where they think to be secure from molestation and harm in
carrying out the chief object of their being.
The young are fed at first on various larvæ, especially those of a
lepidopterous character. To these, earth-worms, aphides, beetles and
flies are added as condition and age require. When twelve days old
they are persuaded to leave the nest, and, under the direction of the
paternal sire, receive instruction in bird-lore. A period of eight or
nine days more, and they earn their own living. They do not forsake
their parents, however, but follow them into their old hunting-grounds,
and thus help to constitute the small flocks which are generally
observed in the fall of the year in our Eastern and Middle States,
previous to migration.
The eggs are oblong-oval in shape, and vary considerably in size. They
are of a bluish-green color, and are sparingly spotted with umber and
dark brown markings about the larger extremity. In some specimens,
the latter are grouped after the fashion of a wreath, but this is the
exception rather than the rule. The largest specimen we have ever seen
measures .80 by .57 of an inch; the smallest, .58 by .47. The average
measurement is .72 of an inch in length, and .54 in breadth. The species
as far as known is single-brooded.
[Illustration: 120]
Plate XIII.--PYRANGA RUBRA, Vieillot.--Scarlet Tanager.
|The Scarlet Taxager, a species but little known outside of the
ornithological world, is more generally distributed than the casual
observer is aware. According to various authorities, it ranges from
Texas to Maine, and from South Carolina in a northwesterly direction to
the southern limits of Lake Huron.
In the Eastern parts of Maine and Massachusetts it is but an occasional
migrant; while in the western counties of the latter State, it is
somewhat more plentiful, and nests in high, open woods and time-bewasted
orchards. But it is in the States of Pennsylvania, New Jersey and
Virginia, and throughout the great Valley of the Mississippi, that the
birds more especially abound and rear their young.
Few species are more susceptible to cold and sudden atmospheric changes
than the subject of our sketch. As a necessary consequence it is by no
means a very early comer. However fond it may be of the scenes of last
year's labors and pleasures, it does not forsake the genial climate and
perennial groves of its tropical American home, until balmy April has
yielded her crown and sceptre to the lovely goddess of May.
The male is usually the first to appear, the time of his arrival
antedating that of his sombre-colored, less-favored companion by three
or four days, although cases are cited where the sexes seemed to have
performed the journey together.
For some time subsequent to his advent, the male is shy and suspicious,
keeping away from the habitations of man, lest his brilliant suit
of scarlet and black should excite the envy of some cruel and
conscienceless collector, and he be summarily called upon, at the peril
of his life, to part therewith.
The female, on the contrary, less attractive in style and dress, has
fewer human admirers, and is permitted to roam _ad libitum_, and with
as much freedom and confidence as any of the little feathered creatures
that crowd about our doors.
But a change comes over the males after the lapse of a week or ten days.
They may now be seen along our thoroughfares, and in our fields and
gardens, acting with none of their former timidity, but endeavoring,
by their beautiful plumage, agreeable manners, sweet song and useful
service, to ingratiate themselves into the favor and esteem of their
human brethren.
Thus affairs continue for nearly a month, the sexes crossing and
recrossing each other's paths in their many journeyings, and so intent
upon the procurement of food, that the object of their mission is either
entirely lost sight of, or else is held in check, for the nonce, by some
strong impulse of their being.
Events, however, are ripening for a speedy fulfilment of the business
that has called them hither. The males exhibit less anxiety about
food-questions, and a positive distaste for the unsettled and lonely
lives which they have been leading. A similar feeling, but less
conspicuously manifested, pervades and animates the gentler sexes, if
outward actions afford proper criteria for judging of internal emotions.
But exceedingly more coy than their imperial lords, they keep at a
respectable distance, preferring to be wooed and won, rather than assume
any other _role_ in the drama.
The duty of taking the initiative step falls to the lot of the male.
In order to accomplish this purpose more effectively, perhaps, as he
thinks, he seeks the tall tree-tops, and for many a long and weary hour,
thrills the ambient air with his sweetest music. We have seen many
a venturesome fellow, seemingly unconscious of his surroundings, and
wholly absorbed in his voluntarily-imposed task, take his station upon a
lofty tree by the road-side, in full view of passers-by, and pour forth
his harmonious utterances with all the animation and pathos of his
being. Tired at last, he ceases his efforts, preens his feathers, and
is off to try his fortunes elsewhere. Thus he keeps up these movements,
with necessary intermissions of rest and recreation, during the livelong
day, until his song has arrested the attention of some impressible
female. This ditty, which is uttered in a low and pensive manner,
and which may be rather accurately represented by the syllables
_chi-chi-chi-char-ee-char-ee-chi_, has been likened to the well-known
notes of the Baltimore Oriole, but we are unable to trace the least
resemblance thereto.
His efforts being finally crowned with success, the happy lover is
profuse in his attentions and caresses, and leads his willing bride
to other scenes, where they spend a brief season of enjoyment, before
entering into preparations for establishing a home. As they move through
the branches and foliage together, they utter their affection in a low
whispering warble, and in tones of singular sweetness and tenderness.
Having celebrated their nuptials, they settle down to the duties of
nest-building in earnest. The selection of a site is the first thing
that commands attention. This is a matter of no little importance, and
one that requires the exercise of considerable judgment. Both birds
generally go together 011 this essential business, and carefully ransack
the fields and thickets until a location is obtained which is wholly
eligible. Nothing occurs in these examinations, if we are to judge from
the behavior of the participants therein, to give offence, or mar the
happiness of the wedded pair.
The places selected vary according to latitude and the fancy of the
builders. Orchards, and groves of chestnuts, oaks, and nut-trees are
frequented, and often a preference is manifested for swampy woods if
not too dense. In places contiguous to human habitations the builders,
especially the male, act with less carefulness than in more retired
localities. They are here more secure from the depredations of rapacious
birds, the latter having a decided aversion to man, their inveterate and
merciless foe.
Building operations are usually begun about the fifteenth of May in the
latitude of Philadelphia, towards the close of the month in New England,
but never later than the first or second week of June. In its southern
breeding-quarters, following the examples of its more distant relatives,
it doubtless nests earlier.
The nest is placed upon the horizontal branch of a fruit-tree, usually
on the edge of a wood, but occasionally in an orchard. Sometimes it is
built over a crotch, which constitutes a more stable position. When a
nest is located on the outskirts of a thicket, some species of oak, or
the tulip-tree, is generally selected as the recipient thereof. In an
orchard, the apple claims and receives this honor. Its height above the
ground is mostly from fifteen to twenty feet in sequestered situations,
but in cultivated districts, a much lower elevation is chosen.
The labor of building is performed mainly by the female, her partner
lending but little assistance. The time devoted to the task seldom
exceeds a period of four days, and so loosely are the fabrics put
together, in the majority of cases, that they scarcely survive the
season for which they were intended.
A structure before us is rather symmetrical and neatly built for the
species, and quite shallow. Externally, it is composed of dried twigs,
weeds and grasses, variously intermingled. Internally, there is a lining
of fine roots, grass-stems, and the inner bark of the chestnut and
oak. The outside diameter is five and a half inches, height two inches,
diameter of cavity three and a half inches, and depth about half an
inch.
Mr. Nuttall describes a nest examined by him as composed of rigid stalks
of weeds and slender fir-twigs joined together with narrow strips of
apocynum and pea-vine runners, and wound around with thin wiry stalks
of the helianthemum, the whole so loosely and thinly plaited as to admit
the light quite readily through the interstices.
The Plate represents the average structure. On examination it will be
found to be nearly circular above, although somewhat irregular towards
the lower two-thirds. The hase is rather loosely constructed of strips
of bark, fine stems of vegetables with dried flowers attached, and
rootlets of woody plants. Upon this as a basis is wrought, with more
compactness and finish, a framework, which is beautifully lined with
reddish-brown stems of herbaceous plants, and fine strips of inner bark.
The external diameter is five inches, and the height, two inches. The
diameter of the cavity is three inches, and the depth one-half of an
inch. This nest is shown in its natural position over and partly between
a forked branch of one of our common species of oak. The female bird is
placed upon the right, as though about to assume the duty of incubation;
while her illustrious partner occupies a very dignified position on the
left of the picture. All the figures, however, are reduced one-third, so
as to bring them within the scope of the page.
Having completed her home, the female almost immediately commences to
deposit her complement of four or five eggs, at the rate of one a day,
in as many consecutive days. This business being attended to, on the day
succeeding the last extrusion, she takes the nest, and for a period of
twelve or thirteen days of rather close sitting, supplies the warmth
necessary to develop her house-full of children.
It is a remarkable fact, and one that beautifully displays the wonderful
wisdom which is taught by Nature, that the brilliantly-colored males
studiously avoid the nest, and only approach it, when necessary, with
caution and stealth, for fear of betraying its presence; while the
females, with their plain coloring in harmony with the surrounding
foliage, sit thereon, and care for their helpless offspring without
danger of molestation. But if the nest is approached with hostile
intention, or is actually invaded, the males emerge from their places of
concealment, and assist in carrying its precious treasures away. But
how this is accomplished, it is impossible to say. Mr. Minot has known
instances where the young have been removed, although many of the cases
seemed to be beyond the ability of bird-ingenuity to accomplish.
On one occasion, while our worthy friend was ascending a tree which
contained a nest of this species, and that, too, with as much care and
quietness as was possible under the circumstances, he was surprised to
see the parent birds return several times to the tree upon his arrival
at a point which commanded full view of the inside of the domicile.
Although the nest was known to contain eggs, which were seen through
the interstices from below, his astonishment was undoubtedly heightened,
when he discovered it to be empty. He immediately began an examination
of the premises, but could find no pieces of broken shells, or traces
of yolk on branch, or on the ground beneath. The eggs had certainly
been spirited away, but whether they were afterwards returned and
successfully hatched or not, he was unable to say.
Notwithstanding the precaution which these birds take in the selection
of a building-spot, and the artfulness with which they seek to conceal
their home by means of the surrounding leaves, it is a fact, not
generally known, but nevertheless true, that much of their prudence and
painstaking counts for naught. They may deceive the trained collector,
but they cannot elude the sagacity and watchfulness of the female
Cowbird, who is ever on the alert and ready to slip into their
unoccupied nest and deposit her own egg.
We have known instances where as many as three of these parasitic eggs
had been left in the nest alongside of one of the rightful occupant's
eggs. A case of the kind came to notice last summer. But whether the
owners of the nest would have hatched the intruders or not, we cannot
say, as its contents were rifled shortly after the discovery had been
made. Owing to its shallowness, it is highly probable that the owners
would have thrown them out on becoming cognizant of their presence. With
small birds, and also with those which are in the habit of building deep
nests, there is considerable difficulty attending such an attempt. The
birds are generally obliged to submit to circumstances, and hatch the
aliens.
The food of the young is chiefly collected by the mother-bird, and
consists of the larvæ of beetles, various species of lepidoptera with
mature forms of the same, spiders, plant-lice, diptera and earthworms.
These are fed to them for the space of a fortnight subsequent to their
leaving the eggs, when they quit for the first time the close precincts
of their shallow home, to receive their earliest impressions of the
outside world, or to take some lessons in the secrets of bird-lore.
Another week more, and they are thrown upon the cold and pitiless world
to fight their way as others have done before.
The devotion of the parent to her young is shown not only in the
assiduity with which she labors to supply them with the essential
articles of diet, but also in the distress which she manifests when they
are in perilous situations, and in her efforts to extricate them from
the same.
Wilson relates a very touching instance of such devotion. Having taken a
very young bird from the nest, he carried it to his friend, Mr. Bartram.
The latter gentleman placed it in a cage, which he suspended near a nest
containing young Orioles, in hopes that the parents of these birds
would be moved to feed it. This they failed to do. Its cries, however,
attracted its own parent, who diligently attended it, and supplied it
with food for several days. At length she became so solicitous for its
liberation, as evidenced by repeated cries of entreaty, that Mr. Bartram
could bear it no longer. He immediately mounted to the cage, took out
the captive, and restored it to its parents, who accompanied it to the
woods with notes of great exultation.
Early in August the male begins to moult, when, after a little, he
appears in the greenish livery of the female. In this stage he is
not distinguishable from her or his young family. Now is the time for
departure, and parents and young forsake with many regrets the land
where they have experienced so much real happiness, for the sunny groves
of Mexico and Peru, or the breezy forests of their West Indian home.
The eggs of this species vary from an inch to .90 in length, and have an
average width of .65. The ground-color passes from a well-marked shade of
greenish-blue to a dull white with scarcely the faintest tinge of
blue. In some the spots differ in size, are more or less confluent, and
chiefly of a reddish-brown color intermingled with a few others of an
obscure purple. As a rule, there is a notable resemblance to each other,
in the eggs of the same nest-complement, except where, by reason of
pillage, or some adventitious circumstance, the female is called upon to
deposit, after she has already furnished the necessary number, in order
to compensate for those that have been taken or destroyed. It may be the
earliest-laid eggs that have escaped the avaricious oologist. In that
event, the additional ones must necessarily be lighter in colors, and
contrast very strongly with those which remain. Locality has doubtless
much to do with color-variations, southern specimens being more sharply
defined than those from colder latitudes.

Plate XIV.--HIRUNDO HORREORUM, Barton.--Barn Swallow.
|The Barn Swallow, the chief of its fellows, is the most widely
diffused, most generally abundant, and, wherever found, the best known
of all our species. None are more universally or deservedly popular.
It ranges throughout North America from Florida to Greenland, and from
the Atlantic to the Pacific Ocean, breeding, strange to say, over nearly
the whole of this vast territory.
Such is its attachment to last year's scenes and associations, that it
leaves its far-off home in the sunny South rather early, gathering its
forces from the plains of Brazil, the spicy isles of the Indies, and the
lofty plateau of Mexico, and wends its graceful flight northward.
Unlike many of its kin, this familiar little species does not wait until
the soft mild days of May have visited the earth, but, actuated by an
overmastering instinct to revisit the land of its nativity, it comes ere
the dying throes of the winter-demon have ceased to be heard in the wild
March winds.
But the more genial fields and streams of our Southern border-states
first invite its presence, and offer it an abiding-place, until its
more northern habitats are made to rejoice under the influence of
the sun-god. In the Central section of this great land of ours, this
generally occurs during the early days of balmy April, when spring may
be said to commence in earnest.
Hundreds of these agile creatures, carried away by the exuberance of
their feelings, may now be seen either disporting themselves in the
atmosphere, or more profitably engaged in pursuing their multifarious
prey on swift and noiseless wings.
While some remain in these parts to breed, others retire further north,
and take up their quarters in old accustomed haunts; reaching New
York and Southern New England towards the close of April, and the
more northern portions of the latter section about the first of May.
Continuing their migration, a few, according to Sir John Richardson,
pass on until they have attained the latitude of 67° 31', where they
stop to breed. This doubtless occurs about the last of May, or the
beginning of June, if the fact of their nesting at Fort Chippewayan, ten
degrees further south, on the fifteenth of May, affords any basis for
computation.
On the Pacific coast these birds are less abundant than 011 our Eastern
shores. This is attributable to the lack or scarcity of suitable
building-places. As settlements multiply, they increase in numbers,
especially in the neighborhood of farms. Farther inland, the species is
conspicuous for its rarity.
From the time of its arrival until its departure about the first of
September, and even during the breeding-period, this Swallow delights
in society. When foraging for food, it is not unusual to see varying
numbers of birds engaged in the same useful occupation. This habit of
gregariousness, which evinces a love for the companionship of its kind,
instead of dying out, as is generally the case with many species that
might be cited, continues to exist, and manifests itself during the
time of nesting by a desire to dwell in communities. But this is not
everywhere the case.
In some parts of the country, particularly in the extreme north, the
sexes appear to come together only upon arrival at their places of
destination. Mating commences either while the birds are in transit, or
immediately upon the conclusion thereof; and as nesting commences when
they have reached the end of their journey, it is reasonable to conclude
that the two follow each other in close succession, leaving no time for
the display of those curious antics so characteristic of the feathered
creatures.
But in lower latitudes, the first two or three weeks after the arrival
of these birds, is spent in the procurement of food. The good which is
then accomplished, cannot be fully appreciated, and is of such immense
value as to gain for the species the high position which it occupies in
the affections of mankind.
During the whole of this time, we have seen nothing that would appear to
indicate that courtship is indulged in. Perhaps this necessary business
of bird-life is practised in mid-air, while the sexes are skimming
through the swaying fluid, or circling in joyous company high overhead.
May not the pleasing, lively succession of twitterings which drop
earthward, when these lovely creatures are careering towards the dome of
heaven, he the love-songs which the males are pouring into the ears of
listening females? To be fully appreciated, they should be heard during
these exciting aerial movements. When perching, the birds seem
less animated; consequently, the music is slower, but none the less
agreeable.
Whether this business is in vogue or not among these birds, matters
little, so long as the important duty which has brought them hither is
accomplished. That this is the case, is indisputable, as the sexes are
known to separate from the flocks, and repair to accustomed haunts to
build.
The period of nesting varies somewhat according to latitude and the
conditions of the weather. In the West, nests have been found with eggs
as early as the thirtieth of April, but this was in the vicinity of San
Francisco. In semi-tropical regions, it is reasonable to look for an
early assumption of matrimonial relations. But in the generality of
instances, outside of our warm Southern latitudes, the birds commence
to build their domiciles from the fifteenth to the last of May, and, in
some cases, even running into the first week of the month that follows.
In the construction of a home, which is usually the work of six days,
the builders apply themselves with persevering assiduity, only stopping
from their labors, for brief spells of time, in order to rest, or to
procure the essential articles of food.
The places selected for this purpose are strange and various. In the
wild districts of the West, the birds nidificate in caves that abound in
the bluffs along the sea-shore. Near Fort Dallas, Oregon, the basaltic
cliffs so common thereabouts are utilized. In the vicinity of Pyramid
Lake, Nevada, their nests are placed among the "tufa domes" attached
to the roofs of caves, seldom more than one or two pairs being found
together. In other localities, in the same section of country, limestone
cliffs, crevices of rocks, and sides of wooden bridges, serve the same
purposes.
Coming East, where they are much more familiar and confiding, we find
quite a change in this particular. Venturing into our crowded cities,
they often build their elaborate homes in the porches of dwellings.
But the various farm-buildings, which are noticeable in agricultural
regions, are generally to be preferred. In such places, the nests are
erected on horizontal rafters, or secured to the frameworks, underneath
the eaves, after the fashion of the Cliff Swallow's nest. Again, bridges
and dilapidated spring-houses are occasionally pressed into service.
Besides the foregoing, cases have been cited where the nest of the Cliff
Swallow was used, and also one where a small building, of very rude
structure--which was temporarily occupied as a blacksmith-shop--was
utilized.
Their natural breeding-places, before the settlement of this country,
were caves, overhanging cliffs, and like situations. Swallow Cave, at
Nahant, was formerly a favorite place of resort. As the country becomes.
settled, these places are forsaken for the more convenient ones which
the buildings of the farm afford. Such accommodations, experience has
shown, tend to a rapid increase in their numbers, for the birds are not
slow to perceive the advantages which result from a close familiarity
with man.
The nests are constructed of separate layers of mud, from ten to twelve
in number, which are often, though not always, parted by strata of fine
grasses. The layers themselves are formed of small pellets composed of
clay and fine sand, worked over by the birds, and which are adjusted
side by side until each layer is complete. The walls being finished,
the circumscribed cavity is stuffed with fine soft grass, and is warmly
lined with downy feathers. The average height and breadth of such
structures when placed on the horizontal rafters of barns is about five
inches. The cavity is usually three inches wide at the rim--thus making
the thickness of the walls an inch--and about two inches in depth. When
placed against the side of a house or of a barn, a strong foundation of
mud is usually built, upon which the nest is reared. In that event, the
nest is more compactly made, and varies from the preceding, by its more
elongate form.
A striking peculiarity of many of these fabrics, is an additional
platform which is placed against the nest proper, but wholly distinct
therefrom. This is undoubtedly designed as a roosting-place, and is used
during the incubating period by the one or the other parent at night, or
when not occupied in the procurement of food, or by both when the young
have complete possession thereof.
A nest before us which was built upon a horizontal rafter underneath
an overshoot, and which may be regarded as typical in the ordinary
scientific sense, is composed externally of ten semi-elliptical series
of mud pellets, slightly overlapping each other after the manner of
tiles, and intercalated with the stems and blades of fine grasses.
Similar vegetable materials are found in small quantities on the
outside, which serve to strengthen the pellets, thus acting as
substantial girders to the entire structure. On the inside is a small
layer of the stems of our common timothy grass, which is followed by
another of greater compactness, and, finally, by a lining of soft meadow
grass. The entire length of this nest is four inches, and it gradually
tapers from above downwards, giving the appearance of a longitudinal
section of an inverted cone. The depression is two and a half inches
wide in one direction, about four in the line of greatest width, and
scarcely an inch in depth, the shallowness being compensated for by the
greater length transversally.
The Plate represents a nest which is nearly the exact counterpart of
the one just described, differing immaterially therefrom in the lack of
grasses between the layers of mud on the outside, and in having a lining
of feathers. The dimensions are about the same in the original, but have
been somewhat reduced in the cut, owing to the size of the page. The
female is shown upon the edge of the nest, peering therein, while her
stronger half is on the wing, and evidently homeward-bound. In the
natural position this elaborate structure was completely protected by
the eaves of the building against which it reposed, but in order to show
the inner arrangement, as well as the eggs _in situ_, the artist was
compelled to leave it partially exposed.
The nest being completed, two or three days elapse before the female is
ready to deposit her first egg. Having commenced, she continues to do
so, at the rate of one a day, until her full number is laid, which,
according to what shall constitute her complement, requires from four
to six days. Incubation immediately succeeds, and lasts for eleven
days. This is not exclusively the work of the female. Sometimes
her affectionate husband relieves her for awhile. But when not thus
employed, he occupies his spare moments either in fetching her some
dainty article of meat, or in guarding his home from intrusion.
Few species show less dread of man during these times. Such is the
confidence which is reposed in him, that the sitting-bird will keep to
the nest, and allow him to pass within a few feet of her. But, on the
other hand, if any interference is attempted, she glides noiselessly
out, and watches and contemplates his movements with few, if any,
murmurs of complaint.
An interesting account is given of these birds by Mr. J. K. Lord. While
he and his party were encamped at Schyakwateen, in British Columbia,
a small shanty, loosely constructed of poles, and tightly roofed, was
erected, and used as a blacksmith's shop. Early one morning, late in
June, they were visited by a pair of Swallows, who instantly perched
on the roof of this shed, unmindful of the noise of the bellows, or the
showers of sparks that flew around. Presently they entered the house,
and commenced an examination of the roof and its supporting poles,
twittering to each other the while, in the most animated manner. At
length the matter appeared to be settled, and on the ensuing day they
commenced the erection of a building on one of the poles directly
over the anvil. Though the hammer was constantly passing close to the
structure, yet the fearless builders kept steadily at work, and in about
three days had completed the rough outline thereof. A few days more, and
their home was ready for occupancy. The narrator often stationed himself
upon a log to watch them, with his face so near, that their feathers
frequently brushed against it as they toiled at their task. Suffice it
to say, the eggs were laid, the young hatched and successfully reared,
and the trustful pair maintained their serenity and fearlessness till
the last.
The attentions of the parents to their young are unremitting. The number
of small insects which they collect for them is almost incredible.
Flies, aquatic larvæ, and small moths form a considerable part of their
earliest diet. But as they become older, other insects are added to
their bill of fare. When about fourteen days old they are able to leave
the nest. The manouvres of the parents to entice them out, and the
assistance which they render them in their first feeble attempts
at flight, are among the most curious and interesting of all our
ornithological experiences. A few days' training gives them complete
control over their alar appendages, and they are soon as merry and happy
as any of their older companions, as they sail through the air in quest
of insects, or in the pursuit of pleasure. By the first of September,
they are strong enough to endure the fatigue incident to the long
journey which they are called upon to make, in obedience to the supreme
law of their being, at this season of the year.
The eggs of this species are white with a roseate tinge in unblown
specimens, and are marked with spots of reddish and purplish brown,
varying in size and number, but chiefly collected about the larger end.
From the Cliff Swallow's eggs, they differ in having finer spots, and
in being smaller and rather more elongated. Specimens from different
localities, and even in this region, show marked variations in length,
some being .95 of an inch, and others; not more than .74. The same bolds
good with respect to the width; the greatest being .63 of an inch, and
the least .50. The average dimensions are .77 by .55 of an inch. The number
of broods generally raised is two, the latter often as late as the
last of July, or the beginning of August. This is not always the case,
especially when the season has been unusually delayed by means of the
weather, or when the natural instinct has been unaccountably restrained.

Plate XV.--LOPHORTYX CALIFORNICA, Bonaparte.--The Valley Quail of
California.
The Valley Quail--so called in contradistinction to the Plumed or
Mountain Quail, which inhabits hills and highlands--has an exceedingly
limited range. It abounds in all the valleys of California and Oregon,
both inland and maritime, but never in the forest-depths, nor on the
mountain-tops, nor in the interior basin where there is a dearth of
water and vegetation. In the spring of 1857 these birds were introduced
into Washington Territory, on the grassy plains near Puget Sound, where
they soon established themselves.
According to Dr. Cones, who has paid special attention to the
distribution of our birds, the present species ranges from the Columbia
River to Cape St. Lucas. In California it is chiefly restricted to
the country west of the Sierra Nevada, which, with the Great Colorado
Desert, is said to constitute an apparently impassable barrier between
it and Gambel's Partridge--a very near relative. Up the mountains a
higher elevation than three or four thousand feet is never known to be
attained, the region beyond being occupied by the Mountain Quail.
Prairies and grain-fields, and thickets along the borders of streams,
are noted places of resort. Coveys of from a dozen to a hundred or more
individuals may be seen in such places, during the non-breeding season,
busily employed in gleaning, or in some sort of diversion. Although
comparatively tame, and permitting a very near approach, yet when
disturbed, they betake themselves to the bushes or trees. When to the
latter, they squat so closely along the branches, as to escape the keen
sight of pursuers. It will not lie to a dog, as our Eastern species is
wont to do, but runs until driven to seek safety in flight.
Throughout California these birds are often domesticated, and made to
consort with the common barnyard fowl. A similar practice might be tried
in the East with happy results. That it would succeed, there can be no
reasonable doubt. A few years ago, an attempt was made to introduce them
into Long Island, which was only partially successful. But the demands
of New York epicures soon led to their extermination.
The season of flocking being over, which continues from the first of
September until about the middle of May, as nearly as we can ascertain,
the coveys break up into pairs, and mating is about to commence.
This important event is heralded by certain peculiar cries which the
male-birds emit while sitting upon a stump or prostrate log in the midst
of the surrounding verdure. These notes are very strange, and may be
likened to the harsh and disagreeable tones of some of the Woodpeckers.
"They may be aptly represented," says Dr. Newberry, "by the syllables
_kûck-kuck-kûck-kâ_, the first three notes being rapidly repeated, the
last prolonged with a falling inflection."
Language can hardly describe the actions of the males during these
times. While some may be seen strutting along some fallen log, or
gesticulating overhead on the motionless tree-branches, others, less
lofty in their aspirations, move with dignified demeanor in and out the
bushes, untrammeled by interlacing grasses. All, however, seem animated
by one common impulse--the admiration and favor of birds less beautiful,
perhaps, but more modest, than themselves.
It is a charming sight, and one ever to be remembered, to watch these
enamored birds as they press their several suits. The stately tread,
erect but comely carriage, waving plumes, quivering wings, and flashing
eyes, bespeak the proud consciousness of superior worth and vigor. The
beautiful bird glances defiantly about him, and challenges loudly for a
rival. Again, he throws down the gauntlet, but none appears to take it
up. He may now retire; his rights are proven.
But hid away in leafy bower, a gentler being watches his movements,
admires his bearing, and fascinated by the courage she sees displayed,
hopes that the next movement may bring him to her side, but dreading
lest it may. At length their eyes meet, she trembles and attempts to
fly, but cannot. Another look; he reads the secret of her heart, and
with one loud, exultant cry, flies straight to her, curtsies low, and
with wing half-spread above her, whispers softly in her ear the story of
his love. She listens, but draws away. He pleads once more. She stands
irresolute. Again he makes the attempt. This time with all the eloquence
of his being. He conquers, and what a joy is his!
The trial over, the prize secured, the delighted lover, proud of his
bride, showers upon her the rich fruitage of his love, guards her
with jealous care, and seeks by every means in his power to add to her
comfort and happiness. A few days thus spent, and the wedded couple,
conscious of the sense of responsibility which attaches to them, cast
about for a suitable spot for a home. They search through the tall, rank
herbage, among piles of driftwood that lie scattered about, under fallen
cacti, or in the shadow of jasmine bushes, and at length make up their
minds. Where none of these are to be found, they do not hesitate to take
to an open field. Little more is needed than to fix upon a spot, for the
nest is far from an elaborate affair, being aught else than a collection
of loose, dry grasses arranged without much care. In many instances,
even these articles are dispensed with. The Plate represents the
ordinary style of nest, containing a set of thirteen eggs drawn to the
natural size. On the left of the picture may be seen the male, which
differs from the female in his more brilliant and vivid colors, both
being placed in the background.
Having finished her simple domicile, or rather having chosen a spot,
for laying--for in the generality of cases no nest whatever is made--the
female deposits day after day the eggs which are to constitute her
complement. These are said to be from twelve to sixteen in number. When
not pressed to lay, she rambles about with her lord, in close company,
until compelled to take the nest. She now abandons all recreation,
becomes sober and maternal, and sets about her duty in earnest. But
she is not forgotten because she cannot enter into his idle amusements.
Mounted upon some bush or log which projects above the nest, he stands
watch, or solaces her weary moments with his best music. This ditty,
though far from being harmonious, is presumably satisfactory to the one
concerned. The time spent in incubation lasts for two weeks or more,
until feeble cries are heard from the nest. The mother-bird now dries
and cuddles the queer little beings, and the happy parents soon lead
them off in quest of food. When the young are disturbed by human foes,
the male-bird utters a sharp _pit_, resembling the common note of the
Cardinal Grosbeak, which is doubtless the signal for flight.
The eggs of this Quail differ somewhat in size, and also in
ornamentation. The ground-color is usually a creamy-white. The markings
sometimes occur in the form of freckles, at other times in large
scattered spots, and frequently in the form of confluent blotches.
Their colors pass from a uniform shading of olivaceous-drab, through a
rusty-drab, into a chestnut-brown. All the specimens that we have seen
are sharply defined at one extremity and rounded at the other. In a set
of fourteen eggs before us, the largest measures 1.32 by 1.00 inches;
the smallest 1.13 in length and .97 in breadth. The average size is 1.23
by .98 inches. From the number of eggs sometimes found in a nest, it
becomes a question whether birds, severely pressed, may not sometimes
lay in nests not their own. We have no positive information that this
does happen, but observation renders it highly probable that such is
the case with the Virginia Quail, and, also, with some other birds.
But however this may be, it is tolerably certain that broods of young
sometimes coalesce after hatching. It has even been inferred that
several females belong to one male, and with their varying broods run
together.
[Illustration: 146]
Plate XVI.--REGULUS SATRAPA, Licht.--Golden-crowned Kinglet.
The Golden-crowned Kinglet, or Wren, ranges over nearly the entire
continent of North America, from the Atlantic to the Pacific Ocean, and
northward from Texas and New Mexico to Sitka on the west, where it seems
to replace the Ruby-crown. On our eastern seaboard it doubtless attains
as high a latitude. Audubon claims to having found it nesting in
Newfoundland, and Baedecker, in Labrador, but recent travelers have
certainly not encountered its presence during the breeding-period in
those parts, since they have left no record of such occurrence.
In the United States, until recently, it was generally supposed to be
a migrant; arriving pretty punctually in October, just as autumn is
merging into winter, and remaining till May. But the past five or
six years have let in new light upon its history, and shown, what had
already been surmised, that it would be found to breed in the coniferous
forests, and mountainous regions toward our northern border.
Our knowledge of the species is limited, and is mainly restricted to its
habits during its long stay with us from October to May. Every one who
has left the shadow of home, and strayed out into the fields and woods,
or along the margins of ice-bound streams and ponds, must have had
his attention directed to its cries as it flitted from tree to tree
in search of food. At such times, the sexes remain apart, or but
occasionally come together. Although shunning, rather than courting
each other's society, their casual meeting is not the harbinger of
contention, but is either tacitly acknowledged, or passed by unnoticed.
While there seems to be an indisposition to mingle, yet evidence is not
wanting to show that society of some kind is not wholly disagreeable.
Either sex manifests, or seems to manifest, some regard for the
Black-capped Titmouse. Wherever you discover the one, you are
pretty sure to find the other. This occurrence does not appear to be
accidental, but rather to be dictated by a desire for company, or by
actual necessity.
Although evincing a decided partiality for Nature in her wildness, on
warm, sunshiny days in mid-winter our little friend may frequently
be seen climbing about our trees after the fashion of a Creeper, or
standing beside our doors in anxious expectation of receiving his
share of crumbs from the table. He is now the very impersonation
of fearlessness, and conducts himself with all the familiarity of a
long-tried friend.
But as spring returns, a peculiar cry greets the ear, louder and more
frequent than usual. _Tsi-tsi-tsi_ comes from wood and glen, from stream
and hollow. Once heard, these syllables can never be forgotten, for
they are uttered in a running, pleasing rhythm, and with a gently-rising
intonation, and seem indicative of joy and satisfaction. But as the
season for departure arrives, these sounds give place to others of a
more agreeable character. Even in the heart of winter this music may be
heard. Perhaps some precious reminiscence of the past has arisen in the
memory to evoke this flood of song.
Full of expectancy and unrest, about the middle of May--often earlier,
seldom later--the little Golden-crown wings its flight to other scenes.
Of the exact time, we know nothing. It does not stop to bid us an
affectionate adieu, but is gone before we are hardly aware of the blank
which it has left. Its return is as unheralded and mysterious. To-day
we admire its graceful actions, sprightly ditty and beautiful plumage.
To-morrow we search the old haunts, feeling almost confident that it
must be lurking somewhere about, but to be doomed to disappointment.
Occasionally our patience is rewarded by finding a couple of
individuals, who have either lost their reckoning, or have made up their
minds to spend the summer at home. But the most of their fellows still
follow the path which their ancestors have so long trodden.
While some follow the stretch of country between our two great western
mountain systems, and breed in Washington Territory and the country to
the northward, others forsake their winter-quarters, and travel in a
northeasterly direction to the shores of Newfoundland and Labrador. A
few, however, lag behind and find suitable summer resorts in the pine
forests and Thuja swamps of New Hampshire and Maine. When our mountain
regions and dense forests are better known, we hazard the opinion
that many will be found to breed nearer home than we are aware. Paired
individuals have often been met with along the hills of the Wissahickon,
in Pennsylvania, during the breeding-season, which evidently had nests,
but diligent search failed to reveal the fact.
Before the discovery of the nest of this species, the presumption was
that it built a pensile nest, not unlike the European congener, and that
it laid small eggs faintly sprinkled with buff-colored dots on a white
background, but differing little in size from those of the common
Humming-bird. It was also inferred that two broods were annually raised,
from the fact that so much time was spent in its summer abode, and also
because full-fledged young were found by Mr. Nuttall in May, on the
Columbia, and in August, by Mr. Audubon, in Labrador.
According to Mr. J. K. Lord, who discovered this species to be very
common in Vancouver's Island, and also along the entire boundary-line of
Washington Territory and British Columbia, where it sometimes reaches an
elevation of six thousand feet, it constructs a pensile nest, which it
suspends from the extreme end of a pine-branch; and that it lays
from five to seven eggs. The materials of the nest, and the color and
dimensions of the eggs, were never described.
The world remained in ignorance of these matters until the summer of
1875, when Mr. H. D. Minot discovered, on the sixteenth day of July, a
nest of this species. It was built in a forest of the White Mountains,
which consisted chiefly of white birches and evergreens. The nest
was securely fastened to the twigs of a spreading hemlock-bough, was
globular in shape, and placed about four feet above the ground. The
outside was composed of hanging moss and bits of dead leaves; the
inside was chiefly lined with feathers. There can be no doubt as to the
authenticity of this nest, as Mr. Minot observed the parents in the act
of carrying food to their young, and was enabled to track them to their
homes.
But the structure from which the drawing was made--found near Bangor,
Maine--was presented to Mr. Harry Merrill, in the summer of 1876. It
was placed about six feet from the ground in a mass of thick growth so
peculiar to many of our fir trees, and is chiefly composed of moss on
the outside, with a few small fragments of chips, and is lined with hair
and feathers, the latter principally. The external diameter is four and
a half inches, and depth outside nearly three inches. The opening is at
the top, and measures about one and three-fourths inches across, and two
in depth. Although the birds that built this nest were not seen by
Mr. Merrill, yet by the pretty sure evidence of exclusion, they cannot
belong to any other species than the one under consideration.
Of their habits while with young, our knowledge is small. It is evident,
however, from what Mr. Minot says, that both parents supply their
nestlings with food. Incubation is doubtless performed by them both, the
female assuming the bulk of the labor. Unlike many species, these birds
do not pass the breeding-season in silence, but keep up, with occasional
intermissions, an animated twittering.
The eggs possibly range from six to ten in number. To the eye they
appear of a cream-white color, apparently covered with minute spots.
Under the microscope, the ground-color is white, with shell marks
of purplish-slate, and a few obscure spots of a deep buff, rather
superficial, to which their dirty tinge is probably due. The largest
egg measures .52 of an inch in length, and .40 in width; the smallest, .47
by .30 inches. The average dimensions of the ten eggs are .50 by .41
inches.

Plate XVII.--UTAMANIA TORDA, (Linn.), Leach.--Razor-billed Auk.
The Razor-billed Auc, owing to its boreal residence, is not so well
known as many other marine species which breed nearer home. Like its
few intimate cousins, it is chiefly restricted to Arctic regions, only
coming southward when pressed by severe weather.
Though apparently the best known of its family, yet many of the
details of its habits are lacking to render its biography anything like
complete. Of its area of distribution we are tolerably well-informed.
In the north-eastern portions of North America, particularly along the
sea-borders of Labrador and Newfoundland, it is quite plentiful, and
thence occasionally strays along the coast-lines of New England and the
Middle States during the winter. These birds, however, are not confined
to this continent, but are identical with the bird of the northern
regions of the Old World.
According to Mr. Cory, who has studied them in their haunts, they are
remarkably abundant and prolific on some of the Magdalen Islands, Bird
Rock and Byron Island especially, where the young birds were observed in
their downy robes of black and white.
Visiting the United States only in small numbers during the inclemency
of winter, its predilection for the northern homes of its fathers--when
the mild breath of spring in its upward march from the South has
tempered with mercy the reign of old Boreas in his rocky, ice-bound
fastnesses--induces it to take its departure, and wend its longing
flight thither.
There is not the slightest evidence, so far as our investigations have
extended, to show that any attempts have ever been made to nest along
the shores of this country. The fact that the species breeds on the
islands in the Bay of Fundy, would seem to warrant the belief that they
may yet be found to visit the coast of Maine for this purpose. There
seems to be no good reason why they should not do so, as the maritime
parts of this State are apparently as well adapted for nesting as the
islands just mentioned.
Be this as it may, cool northern localities seem to be more
advantageous, and there, along with the Guillemots as their neighbors,
the subject of our sketch establishes his home and rears his little
family.
In boreal regions where the amatory forces are not called into action
as early as in more southern climes, by reason of the greater degrees
of cold which prevail, the acquirement of food seems to exercise such a
controlling influence over bird-nature, that all other duties are held
under temporary restraint. Consequently, matrimonial relations are not
entered into as early as in warmer latitudes. This essential business is
delayed, and is only warmed into activity when the sun has reached the
northern limits of its course.
About the beginning of June, there occurs a lull in foraging
transactions, and the sexes become suddenly aware of the object of their
creation. Mating is at once entered into, but with what appearance of
show, we are unable to say.
Having attended to this duty, without further ado, they seek themselves
out a spot in which to lay their egg or eggs. For this purpose a
horizontal cavern or some exposed locality is generally chosen. But
when they deposit their eggs along with the Guillemots, which they are
occasionally disposed to do, they drop them in situations from which the
water can escape without offering any material injury thereto.
In deep fissures, many birds lie together, and place their eggs upon
small beds of pebbles or broken stones, which are raised a couple of
inches or more, so that the water may readily pass beneath them. Here
the eggs are scattered at distances of three or four inches from each
other, and are incubated, as in the case of the Ducks, by the birds
sitting flat upon them. Whereas, upon an exposed rock, each bird stands
almost upright on its egg.
There yet remains a very strange fact concerning this Auk, which needs
to be noted. It pertains to the number of eggs which is to constitute
a nest-full. When nesting occurs in secluded situations, where security
against tidal currents, and divers accidents, is to be gained, in the
majority of instances, two eggs are found under a single female. In
exposed situations, on the other hand, it is a rare occurrence to find
more than one egg as a complement.
The above statements, which are substantially those of Audubon, have
been repeatedly verified by other observers, some of whom are among
the writer's most reliable correspondents. At first we were disposed to
question their accuracy. We could not see what advantages a sequestered
situation had over one that was open and exposed, so as to lead the
birds to double their number in the former case. Our only way out of the
difficulty then, was by supposing the two eggs to be laid by different
birds, in close proximity to each other. For want of the necessary room
to accommodate the two females, it became the duty of one or the other
to assume the responsibility of them. Owing to the great difficulty
of distinguishing the eggs of this species from those of the Murre or
Foolish Guillemot, which most oologists have experienced, and which
Audubon does not seem to have encountered, it occurred to us that as the
Auks are prone to drop their eggs alongside of those of the Guillemots,
maybe the two eggs were those of distinct species, and not the product
of the one under consideration.
Without further mincing of matters, there does not seem to be any valid
reason for doubting the authenticity of Audubon's statements. But as a
true student of Nature, it is our duty to receive the facts, confirmed
as they have been by subsequent observations, and seek an explanation
thereof which will be both rational and philosophic.
In exposed situations, the eggs are subject to certain perils, such as
exposures to storms and violent gusts of wind, which more retired places
would guard against. The Auks have doubtless learned this as a lesson of
experience. Perhaps, necessity only compels them to occupy such sites,
when there is a scarcity of deep fissures and horizontal caverns, by
reason of a superabundance of mated individuals. If one egg could be
better protected and covered than two, which the nearly erect attitude
of the bird would seem to warrant us in believing, some females would
certainly not be slow in perceiving the advantages to be acquired. The
experiment being tried by birds of unusual sagacity, and with happy
results, in course of time all the others would be led to the practice
of depositing a single egg. Furthermore, the laying of one egg, in case
of breakage, would not be as severely felt as in cases where more than
one constituted the complement. The habit of laying one egg in exposed
situations, would doubtless be continued for a while at least, should
the species so accustomed, ever be called upon to nest in places
protected by the rocky munitions of Nature. And, on the other hand,
birds habituated to nesting in sheltered situations, would for a while
continue to deposit two eggs for a setting.
The eggs being laid, the female soon commences to incubate. This seems
to be the exclusive labor of the sex. The fact that she plucks the
feathers from her abdomen, forming one or two bare spots (according to
the number which is to compose her complement) with a ridge of feathers
between them, though circumstantial in character, is the only kind
of evidence that we have to offer in support of our assertion. Of the
precise time required for hatching, we have no knowledge. From the size
of the egg, and the thickness of its shell, we reason from analogy that
it cannot be less than twenty-four days. The female is not a constant
sitter during the daytime, the heated pebbles on clear, sunshiny days
supplying the necessary warmth during her absence. When the weather is
cloudy, and even during the cool nights, she remains on the nest, the
male, as a faithful husband, doubtless answering her calls for food, or
keeping her company.
That these birds manifest true affection for each other cannot be
denied. They may have a different way of showing it from what we are
accustomed to see among our small land-birds, but we cannot speak with
positiveness. But this much is undisputed, when one is killed, its mate
does not desert it, but paddles around it, as if seeking the cause of
its stillness. At such times, so absorbed does it become, whether from
grief or wonder we cannot say, that it can easily be approached and
knocked over with an oar.
The food of the Razor-bills consists of small fishes, roe, shrimps,
various marine animals, and floating garbage, which they procure by
diving and swimming, or pick up among the rocks which they frequent. The
young doubtless subsist upon the same materials, which they receive from
their parents, in small pieces, during their earliest life. But after
they have passed the downy stage, and are thrown, in a measure, upon
their own resources, they imitate the example of their parents.
So much like the eggs of the Foolish Guillemot or Murre, already
mentioned, are those of this species, that it is impossible to discern a
characteristic so peculiar and persistent as to enable us to distinguish
them apart. The ground-color is generally a pure-white; but specimens
are often met with which are cream-colored, and others, again, which are
tinted with green. The spots and blotches are irregularly distributed,
but chiefly about the middle and the larger end. Some are small and
nearly round, others large and irregular. In color they show different
shades of black and brown. In addition to these markings, there are
others scattered over the egg, of an obscure-purple hue, which have the
appearance of being beneath the outside of the shell. The eggs vary in
shape; occasionally they are pyriform and ovoidal, and, at other times,
decidedly ovate.
Their length is 3.19 inches, and breadth 2.13. In the Plate, the egg is
figured the natural size, and placed upon the summit of a small pile of
stones at the entrance to a cavern along a rocky seashore. The birds are
reduced and put in the background, the idea being to show their form, as
well as the arrangement of their plumage.

Plate XVIII.--DENDROECA DISCOLOR, Baird.--Prairie Warbler.
|The Prairie Warbler is nowhere an abundant species. Throughout the
eastern parts of the United States, from Massachusetts to Georgia, it
is pretty generally, though somewhat irregularly, diffused. It is also
found in Kansas, according to Mr. Allen, although unobserved by Dr.
Coues in his western explorations.
Audubon claims to have met it in Louisiana, but his description of its
nesting is so palpably inaccurate, that we are compelled to accept his
statement with misgivings. Wilson obtained specimens in Kentucky, and
to him the species is indebted for the very inappropriate appellation by
which it is known. Nuttall regarded it a rare visitor in the New England
States, yet subsequent observations do not confirm his opinion, but
show, in Massachusetts especially, that it is rather common. In Eastern
Tennessee and Northern Georgia, in the summer of 1880, Mr. Alexander M.
Reynolds, of Germantown, Pa., met with numerous individuals, which had
probably bred in those regions, but no nests were taken.
Although the town of Lynn, Mass., in latitude 42° 30', had hitherto been
accepted as the northern limit of its breeding, yet it was reserved for
H. D. Minot, Esq., to prove that the species often reached the
latitude of Mt. Washington, nearly three degrees further north. Future
explorations will doubtless show that its vernal migration often
surpasses this limit, and reaches even to the Canadian dominions.
In the Middle Atlantic States the writer has obtained specimens early
in May, and has observed in Southern New Jersey, and elsewhere, young
birds just able to fly, but could never discover auy nests. Mr. Jolin
Cassin, in his day, expressed the opinion that these birds certainly
bred in the same State, near Philadelphia, as he frequently met with the
young under similar circumstances. Nests have been taken in Central New
York, but we have no evidence of its breeding in the adjoining State of
Pennsylvania, although individuals have been seen _in transitu_.
Though chiefly a migrant in the United States, yet a few winter
in Florida. But the larger part cross the Channel, after the
breeding-season is over, and spend their time in the delightful islands
which lie to the southward. Here, in January, these once beautiful birds
may be seen in their winter garb sporting amid tropical or sub-tropical
foliage, or hunting the insects that contribute to their bill of fare.
About the beginning of April, sometimes later, they deck themselves in
their summer array, and while some sojourn in these Isles of the Blest
where summer is perennial, and raise their charming little families,
others pine for the cooler groves and fields of the North. Accordingly,
about the tenth of April, all things being in readiness, and at a season
when Nature is weeping herself away in rainy tears, the males apparently
leading the way, the sexes bid adieu to the sights about them, and take
their departure.
Their arrival in the Middle section of our country varies somewhat,
and is dependent upon the season. During some years we have noted their
appearance about the twentieth of April, when the weather was fine, and
at other times not earlier than the first of May. In the vicinity of
Washington, Dr. Coues has found them in pine-trees and cedar-patches,
about the same time. Farther south, in Georgia, for example, the
birds make their advent as early as the tenth of April, preferring the
hillsides to open localities, but it is not until the second or the
third week of May that they reach the New England States.
Few species of the family to which this Warbler belongs arrive sooner,
and none are less shy and suspicious. For more than two weeks they are
denizens of open plains and thinly-wooded regions, where they may be
seen from sunrise until sunset, save during the sultry noontide hours,
leisurely moving along the lowermost tree-branches, or among low bushes
and herbaceous weeds by the roadside, in search of insects, all the
while uttering, at brief intervals, their characteristic _chirr_. Near
Boston they frequent "almost exclusively rocky pasture grounds and the
'scrub,'" and instances are recorded by Mr. Minot where shrubbery in
cultivated grounds has been visited. According to Mr. Gosse, individuals
have been seen to fly from wayside-bushes into the middle of the road,
where, hovering in the air, at slight elevations above the ground, they
were apparently engaged in the capture of dipterous insects.
But as the mating season approaches, the males become quite restless.
They manifest less concern about food, and from some low eminence may
be seen pouring forth their slender, filing notes, which, as Nuttall
has represented, may be very aptly expressed by the suppressed syllables
'_tsh-tsh-tsh-tshea_. These notes cannot fail to attract attention, and,
when once heard, are sure to leave a lasting impress on the mind. They
are uttered in a peculiar tone, each being given in a louder key than
the preceding, and frequently with a strange depression of the tail.
The little musicians, however, have not long to wait. For hours we have
known some love-lorn minstrel of another species to sing his very soul
away, without an answering note to repay him for all his trouble. The
one for which he tuned his vocal pipe was too much occupied by other
cares to be mindful of the delicious strains which were being wasted 011
the desert air. But not so in the present instance. The dear ones for
whom they watch, and for whom they chant their sweetest, purest music,
are not so far removed by hill and dale, by grove and plain, are not
so absorbed in food-concerns, as not to hear the sounds which are being
uttered for their sole pleasure. But obedient to the call, they cease
their feeding, turn listening ears in the directions whence the sounds
issue, and hearing once again, with pleasure-beaming eyes and swelling
bosoms, seek the lonely haunts of their would-be-suitors. The joy of the
males is now unbounded. They strike their harps afresh, and music, it
seems, ten-fold more ravishing, is discoursed. The effect is charming.
The gentle beings feel the notes pulsing through their rapt frames,
and, all-unconscious, yield themselves willing subjects to their proud
conquerors.
Thus it is that mating is accomplished. A few days spent in aimless
wanderings and pleasure-seeking, and the happy pair are prepared to
build themselves a home. For this purpose they visit in company some
wild pasture-land or thinly-wooded tract, where, after a day or two
occupied in prospecting, they decide upon some kind of bush or low tree
in which to place it. The birds do not seem to be very particular as to
the kind. In some localities, a wild rose-bush is preferred. In others,
low barberry bushes, or the lower limbs of post-oaks, are rendered
subservient.
The site, and the kind of bush or tree being chosen, the birds commence
to build. The nest is non-pensile, and is fixed either in a forked
branch, or is supported, as is the case when placed in a wild rose, by
two or more branches. The elevation above the ground is usually from
four to seven feet. No case has come to our knowledge where the latter
height has been exceeded. The period of nesting varies according to
locality. In Georgia nests have been found with eggs as early as the
second of May, which would make it appear that they were constructed
towards the close of the preceding month. In one instance, eggs were
found as late as the tenth of June. It is probable that the birds
commence labor about the first of May, in this section of the country,
and sitting, a fortnight later. In New Jersey this essential business
is delayed until the middle of this month, while in Massachusetts, it is
not undertaken before the first week of June.
Having built their domicile, which is usually the work of a week,
both birds laboring with praiseworthy diligence, and only intermitting
operations when pressed by bad weather and the approach of night, the
female commences to deposit her eggs. These are laid on consecutive
days, at the rate of one a day. The time devoted to oviposition lasts
from three to six days, and is dependent, upon the number which is to
constitute a complement. As soon as the last deposit is made, the female
takes the nest, and continues thereon, save when the male relieves her,
for a period of eleven days, when she is rewarded for her patience and
assiduity, by seeing and hearing a nest-full of callow fledglings. While
the female is thus engaged, the male is busy among the branches of
low bushes and saplings in search of small caterpillars and insects.
Occasionally, he may be seen upon the shrub which supports the nest,
apparently on the alert for intruders, which he signals by a low chirp.
Should the nest be examined, he and his partner exhibit no outward signs
of indignation or lamentation, but remain quietly in the neighborhood
until the danger is past, when they return to their home. If the nest is
ravaged, they set to work to replenish it, wasting little, if any, time
over the contingencies of fate. In case of a second desecration, they
quietly forsake the place, and if the season is not too far advanced,
seek quarters elsewhere, where they endeavor to build a home and rear
their offspring. On approaching the nest the female is very confiding,
and exercises no precautions to guard against exposure, as is the case
with many of our small birds. Nuttall gives a striking proof of this
fact. On one occasion he removed two eggs from the nest, which he
subsequently replaced. Each time, on withdrawal, she returned thither,
but practised no stratagems to lure him away.
In their descriptions of the nests and eggs of this species both Wilson
and Audubon are certainly at fault. They differ from more recent and
reliable observations. The nest, as described by them, is never pensile,
but is scarcely distinguishable from that of the Yellow Warbler.
Xuttall, on the other hand, is not open to the same criticism. The
nest which he describes, was placed in a forked branch, and formed
of caterpillars' silk, strips of the inner bark of the red cedar, and
fibres of asclepias. The inside was lined with the down of a species of
everlasting.
A nest found by Mr. Welch, in Lynn, and described by Dr. Brewer, was
built upon a wild rose, only a few feet above the ground. It was a
compact and elaborately woven fabric, and was composed chiefly of soft
inner bark of small shrubs, bits of dry rose leaves, wood, strips of
vegetables, woody fibres, spiders' webs, decayed stems of plants, etc.,
on the outside, and was lined with fine vegetable fibres and a few
horse-hairs. The outside diameter was two and a half inches, and the
height, the same. The inside diameter was two inches; depth, one and a
half. The above nest, in its general mode of construction, resembled
all he had seen. In other nests he found only variations in composing
materials. While some had dead and decayed leaves instead of fine strips
of bark, others contained the remains of old cocoons, or the pappus of
composite plants.
But the structure from which the drawing was made, was found June 4th,
1875, in the vicinity of Newton, Mass., by J. Warren, Esq. It was placed
in a rose-bush, about three feet from the ground. Outside it is composed
of bark of deciduous trees, vegetable fibres, spiders' webs, old
cocoons, dry leaves, pappus of composite plants, and cotton ravellings.
The inside is lined with the white silken fibres of the wild flax,
constituting a rather dense layer, over which is placed a small stratum
of black and white horse-hairs intermingled with vegetable fibres and
the inner bark of woody plants. The external diameter is two and a half
inches, and the height two. The cavity is one and three-fourths inches,
and one and a half deep. In shape, the nest is nearly hemispherical,
compactly and elaborately made, and, above all, constitutes a very
snug and cosy structure. In these particulars it bears a very close
resemblance to the nest of the Summer Yellow-bird, but differs in the
character of the composing materials, there being less of the satiny
fibres of the flax used in its workmanship.
The eggs are of an oval shape, pointed at one extremity, and measure .09
of an inch in length, and .49 in width. The ground-color is white, and
over it are scattered spots of lilac and purple, as well as others of
two shades of umber-brown. In all the specimens which we have examined
from New England and Northern Georgia the spots are mostly accumulated
about the larger half of the egg, those upon the smaller portion being
finer and less numerous.

Plate XIX.--ZENAIDURA CAROLINENSIS, (Linn.) Bonaparte.--Mourning Dove.
|The Mourning Dove, one of the best known of our American species, is
quite generally diffused throughout the United States. It is found from
the Gulf of Mexico to Colorado, and from the Atlantic westward to the
Pacific Ocean. In the Northern States it is chiefly migratory; in
the Middle Atlantic but partially so; while in the country south of
Pennsylvania it is a winter resident, and manifests a tendency to
gregariousness, flocks of hundreds, and even more, being seen during the
winter in the woods of South Carolina and Georgia.
East of the Rocky Mountains, as well as in the vast region stretching
westward, they occur in greater or less abundance. To be sure there are
localities where they are notably scarce, but only in regions unblessed
by Nature with suitable accommodations for nesting purposes, and with
the essential means of subsistence.
In the South, breeding occasionally takes place early in March, but
ordinarily not before the beginning of April. Not so in more northern
sections. The eighth of March, which is also the time of their
appearance in the Middle States, marks the period of their arrival in
New England, although in Eastern Pennsylvania, during very backward
seasons, their visit is often delayed until the fifteenth of April.
But, in the extreme northern parts of our country, various circumstances
combine to render their coming an event of later occurrence, for we find
that they do not reach the States of Michigan and Wisconsin much before
the twentieth of the month. The vicissitudes incident to change of
climate and new environments all operate to prevent the assumption of
matrimonial relations as early as in semi-tropical climes.
