THE INVITATION

Years ago, when quite a youth, I was rambling in the woods one Sunday,

with my brothers, gathering black birch, wintergreens, etc., when, as

we reclined upon the ground, gazing vaguely up into the trees, I

caught sight of a bird, that paused a moment on a branch above me, the

like of which I had never before seen or heard of. It was probably the

blue yellow-backed warbler, as I have since found this to be a common

bird in those woods; but to my young fancy it seemed like some fairy

bird, so unexpected. I saw it a moment as the flickering leaves

parted, noted the white spot on its wing, and it was gone. How the

thought of it clung to me afterward! It was a revelation. It was the

first intimation I had had that the woods we knew so well held birds

that we knew not at all. Were our eyes and ears so dull, then? There

was the robin, the blue jay, the bluebird, the yellow-bird, the

cherry-bird, the catbird, the chipping-bird, the woodpecker, the

high-hole, an occasional redbird, and a few others, in the woods or

along their borders, but who ever dreamed that there were still others

that not even the hunters saw, and whose names no one had ever heard?

When, one summer day, later in life, I took my gun and went to the

woods again, in a different though perhaps a less simple spirit I

found my youthful vision more than realized. There were, indeed, other

birds, plenty of them, singing, nesting, breeding, among the familiar

trees, which I had before passed by unheard and unseen.

It is a surprise that awaits every student of ornithology, and the

thrill of delight that accompanies it, and the feeling of fresh, eager

inquiry that follows, can hardly be awakened by any other pursuit.

Take the first step in ornithology, procure one new specimen, and you

are ticketed for the whole voyage. There is a fascination about it

quite overpowering. It fits so well with other things,--with fishing,

hunting, farming, walking, camping-out,--with all that takes one to

the fields and woods. One may go a-blackberrying and make some rare

discovery; or, while driving his cow to pasture, hear a new song, or

make a new observation. Secrets lurk on all sides. There is news in

every bush. Expectation is ever on tiptoe. What no man ever saw before

may the next moment be revealed to you. What a new interest the woods

have! How you long to explore every nook and corner of them! You would

even find consolation in being lost in them. You could then hear the

night birds and the owls, and, in your wanderings, might stumble upon

some unknown specimen.

In all excursions to the woods or to the shore, the student of

ornithology has an advantage over his companions. He has one more

resource, one more avenue of delight. He, indeed, kills two birds with

one stone and sometimes three. If others wander, he can never go out

of his way. His game is everywhere. The cawing of a crow makes him

feel at home, while a new note or a new song drowns all care. Audubon,

on the desolate coast of Labrador, is happier than any king ever was;

and on shipboard is nearly cured of his seasickness when a new gull

appears in sight.

One must taste it to understand or appreciate its fascination. The

looker-on sees nothing to inspire such enthusiasm. Only a few feathers

and a half-musical note or two; why all this ado? "Who would give a

hundred and twenty dollars to know about the birds?" said an Eastern

governor, half contemptuously, to Wilson, as the latter solicited a

subscription to his great work. Sure enough. Bought knowledge is dear

at any price. The most precious things have no commercial value. It is

not, your Excellency, mere technical knowledge of the birds that you

are asked to purchase, but a new interest in the fields and the woods,

a new moral and intellectual tonic, a new key to the treasure-house of

Nature. Think of the many other things your Excellency would get,--the

air, the sunshine, the healing fragrance and coolness, and the many

respites from the knavery and turmoil of political life.

Yesterday was an October day of rare brightness and warmth. I spent

the most of it in a wild, wooded gorge of Rock Creek. A persimmon-tree

which stood upon the bank had dropped some of its fruit in the water.

As I stood there, half-leg deep, picking them up, a wood duck came

flying down the creek and passed over my head. Presently it returned,

flying up; then it came back again, and, sweeping low around a bend,

prepared to alight in a still, dark reach in the creek which was

hidden from my view. As I passed that way about half an hour

afterward, the duck started up, uttering its wild alarm note. In the

stillness I could hear the whistle of its wings and the splash of the

water when it took flight. Near by I saw where a raccoon had come down

to the water for fresh clams, leaving his long, sharp track in the mud

and sand. Before I had passed this hidden stretch of water, a pair of

those mysterious thrushes, the gray-cheeked, flew up from the ground

and perched on a low branch.

Who can tell how much this duck, this footprint in the sand, and these

strange thrushes from the far north, enhanced the interest and charm

of the autumn woods?

Ornithology cannot be satisfactorily learned from the books. The

satisfaction is in learning it from nature. One must have an original

experience with the birds. The books are only the guide, the

invitation. Though there remain not another new species to describe,

any young person with health and enthusiasm has open to him or her the

whole field anew, and is eligible to experience all the thrill and

delight of the original discoverers.

But let me say, in the same breath, that the books can by no manner of

means be dispensed with. A copy of Wilson or Audubon, for reference

and to compare notes with, is invaluable. In lieu of these, access to

some large museum or collection would be a great help. In the

beginning, one finds it very difficult to identify a bird from any

verbal description. Reference to a colored plate, or to a stuffed

specimen, at once settles the matter. This is the chief value of

books; they are the charts to sail by; the route is mapped out, and

much time and labor are thereby saved. First find your bird; observe

its ways, its song, its calls, its flight, its haunts; then shoot it

(not ogle it with a glass), and compare it with Audubon. [footnote: My

later experiences have led me to prefer a small field-glass to a gun.]

In this way the feathered kingdom may soon be conquered.

The ornithologists divide and subdivide the birds into a great many

orders, families, genera, species etc., which, at first sight, are apt

to confuse and discourage the reader. But any interested person can

acquaint himself with most of our song-birds by keeping in mind a few

general divisions, and observing the characteristics of each. By far

the greater number of our land-birds are either warblers, vireos,

flycatchers, thrushes, or finches.

The warblers are, perhaps, the most puzzling. These are the true

Sylvia, the real wood-birds. They are small, very active, but feeble

songsters, and, to be seen, must be sought for. In passing through the

woods, most persons have a vague consciousness of slight chirping,

semi-musical sounds in the trees overhead. In most cases these sounds

proceed from the warblers. Throughout the Middle and Eastern States,

half a dozen species or so may be found in almost every locality, as

the redstart, the Maryland yellow-throat, the yellow warbler (not the

common goldfinch, with black cap, and black wings and tail), the

hooded warbler, the black and white creeping warbler; or others,

according to the locality and the character of the woods. In pine or

hemlock woods, one species may predominate; in maple or oak woods, or

in mountainous districts, another. The subdivisions of ground

warblers, the most common members of which are the Maryland

yellow-throat, the Kentucky warbler, and the mourning ground warbler,

are usually found in low, wet, bushy, or half-open woods, often on and

always near the ground. The summer yellowbird, or yellow warbler, is

not now a wood-bird at all, being found in orchards and parks, and

along streams and in the trees of villages and cities.

As we go north the number of warblers increases, till, in the northern

part of New England, and in the Canadas, as many as ten or twelve

varieties may be found breeding in June. Audubon found the black-poll

warbler breeding in Labrador, and congratulates himself on being the

first white man who had ever seen its nest. When these warblers pass

north in May, they seem to go singly or in pairs, and their black caps

and striped coats show conspicuously. When they return in September

they are in troops or loose flocks, are of a uniform dull drab or

brindlish color, and are very fat. They scour the treetops for a few

days, almost eluding the eye by their quick movements, and are gone.

According to my own observation, the number of species of warblers

which one living in the middle districts sees, on their return in the

fall, is very small compared with the number he may observe migrating

north in the spring.

The yellow-rumped warblers are the most noticeable of all in Autumn.

They come about the streets and garden, and seem especially drawn to

dry, leafless trees. They dart spitefully about, uttering a sharp

chirp. In Washington I have seen them in the outskirts all winter.

Audubon figures and describes over forty different warblers. More

recent writers have divided and subdivided the group very much, giving

new names to new classifications. But this part is of interest and

value only to the professional ornithologist.

The finest songster among the Sylvia, according to my notions, is the

black-throated greenback. Its song is sweet and clear, but brief.

The rarest of the species are Swainson's warbler, said to be

disappearing; the cerulean warbler, said to be abundant about Niagara;

and the mourning ground warbler, which I have found breeding about the

head-waters of the Delaware, in New York.

The vireos, or greenlets, are a sort of connecting link between the

warblers and the true flycatchers, and partake of the characteristics

of both.

The red-eyed vireo, whose sweet soliloquy is one of the most constant

and cheerful sounds in our woods and groves, is perhaps the most

noticeable and abundant species. The vireos are a little larger than

the warblers, and are far less brilliant and variegated in color.

There are five species found in most of our woods, namely the red-eyed

vireo, the white-eyed vireo, the warbling vireo, the yellow-throated

vireo, and the solitary vireo,--the red-eyed and warbling being most

abundant, and the white-eyed being the most lively and animated

songster. I meet the latter bird only in the thick, bush growths of

low, swampy localities, where, eluding the observer, it pours forth

its song with a sharpness and a rapidity of articulation that are

truly astonishing. This strain is very marked, and, though inlaid with

the notes of several other birds, is entirely unique. The iris of this

bird is white, as that of the red-eyed is red, though in neither case

can this mark be distinguished at more than two or three yards. In

most cases the iris of birds is a dark hazel, which passes for black.

The basket-like nest, pendent to the low branches in the woods, which

the falling leaves of autumn reveal to all passers, is, in most cases,

the nest of the red-eyed, though the solitary constructs a similar

tenement, but in much more remote and secluded localities.

Most birds exhibit great alarm and distress, usually with a strong

dash of anger, when you approach their nests; but the demeanor of the

red-eyed, on such an occasion, is an exception to this rule. The

parent birds move about softly amid the branches above, eying the

intruder with a curious, innocent look, uttering, now and then, a

subdued note or plaint, solicitous and watchful, but making no

demonstration of anger or distress.

The birds, no more than the animals, like to be caught napping; but I

remember, one autumn day, coming upon a red-eyed vireo that was

clearly oblivious to all that was passing around it. It was a young

bird, though full grown, and it was taking its siesta on a low branch

in a remote heathery field. Its head was snugly stowed away under its

wing, and it would have fallen easy prey to the first hawk that came

along. I approached noiselessly, and when within a few feet of it

paused to note its breathings, so much more rapid and full than our

own. A bird has greater lung capacity than any other living thing,

hence more animal heat, and life at a higher pressure. When I reached

out my hand and carefully closed it around the winged sleeper, its

sudden terror and consternation almost paralyzed it. Then it struggled

and cried piteously, and when released hastened and hid itself in some

near bushes. I never expected to surprise it thus a second time.

The flycatchers are a larger group than the vireos, with

stronger-marked characteristics. They are not properly songsters, but

are classed by some writers as screechers. Their pugnacious

dispositions are well known, and they not only fight among themselves,

but are incessantly quarreling with their neighbors. The kingbird, or

tyrant flycatcher might serve as the type of the order.

The common or wood pewee excites the most pleasant emotions, both on

account of its plaintive note and its exquisite mossy nest.

The phoebe-bird is the pioneer of the flycatchers, and comes in April,

sometimes in March. Its comes familiarly about the house and

outbuildings, and usually builds beneath hay-sheds or under bridges.

The flycatchers always take their insect prey on the wing, by a sudden

darting or swooping movement; often a very audible snap of the beak

may be heard.

These birds are the least elegant, both in form and color, of any of

our feathered neighbors. They have short legs, a short neck, large

heads, and broad, flat beaks, with bristles at the base. They often

fly with a peculiar quivering movement of the wings, and when at rest

some of the species oscillate their tails at short intervals.

There are found in the United States nineteen species. In the Middle

and Eastern districts, one may observe in summer, without any special

search, about five of them, namely, the kingbird, the phoebe-bird, the

wood pewee, the great crested flycatcher (distinguished from all

others by the bright ferruginous color of its tail), and the small

green-crested flycatcher.

The thrushes are the birds of real melody, and will afford one more

delight perhaps than any other class. The robin is the most familiar

example. Their manners, flight, and form are the same in each species.

See the robin hop along upon the ground, strike an attitude, scratch

for a worm, fix his eye upon something before him or upon the

beholder, flip his wings suspiciously, fly straight to his perch, or

sit at sundown on some high branch caroling his sweet and honest

strain, and you have seen what is characteristic of all the thrushes.

Their carriage is preëminently marked by grace, and their songs by

melody.

Beside the robin, which is in no sense a woodbird, we have in New York

the wood thrush, the hermit thrush, the veery, or Wilson's thrush, the

olive-backed thrush, and, transiently, one or two other species not so

clearly defined.

The wood thrush and the hermit stand at the head as songsters, no two

persons, perhaps, agreeing as to which is the superior.

Under the general head of finches, Audubon describes over sixty

different birds, ranging from the sparrows to the grosbeaks, and

including the buntings, the linnets, the snowbirds, the crossbills,

and the redbirds.

We have nearly or quite a dozen varieties of the sparrow in the

Atlantic States, but perhaps no more than half that number would be

discriminated by the unprofessional observer. The song sparrow, which

every child knows, comes first; at least, his voice is first heard.

And can there be anything more fresh and pleasing than this first

simple strain heard from the garden fence or a near hedge, on some

bright, still March morning?

The field or vesper sparrow, called also grass finch 8 and

bay-winged sparrow, a bird slightly larger than the song sparrow and

of a lighter gray color, is abundant in all our upland fields and

pastures, and is a very sweet songster. It builds upon the ground,

without the slightest cover or protection, and also roosts there.

Walking through the fields at dusk, I frequently start them up almost

beneath my feet. When disturbed by day, they fly with a quick, sharp

movement, showing two white quills in the tail. The traveler along the

country roads disturbs them earthing their wings in the soft dry

earth, or sees them skulking and flitting along the fences in front of

him. They run in the furrow in advance of the team, or perch upon the

stones a few rods off. They sing much after sundown, hence the aptness

of the name vesper sparrow, which a recent writer, Wilson Flagg, has

bestowed upon them.

In the meadows and low, wet lands the savanna sparrow is met with, and

may be known by its fine, insect-like song; in the swamp, the swamp

sparrow.

The fox sparrow, the largest and handsomest species of this family,

comes to us in the fall, from the North, where it breeds. Likewise the

tree or Canada sparrow, and the white-crowned and white-throated

sparrow.

The social sparrow, alias "hairbird," alias "red-headed

chipping-bird," is the smallest of the sparrows, and I believe, the

only one that builds in trees.

The finches, as a class, all have short conical bills, with tails more

or less forked. The purple finch heads the list in varied musical

abilities.

Besides the groups of our more familiar birds which I have thus

hastily outlined, there are numerous other groups, more limited in

specimens but comprising some of our best-known songsters. The

bobolink, for instance, has properly no congener. The famous

mockingbird of the Southern States belongs to a genus which has but

two other representatives in the Atlantic States, namely, the catbird

and the long-tailed or ferruginous thrush.

The wrens are a large and interesting family, and as songsters are

noted for vivacity and volubility. The more common species are the

house wren, the marsh wren, the great Carolina wren, and the winter

wren, the latter perhaps deriving its name from the fact that it breed

in the North. It is an exquisite songster, and pours forth its notes

so rapidly, and with such sylvan sweetness and cadence, that it seems

to go off like a musical alarm.

Wilson called the kinglets wrens, but they have little to justify the

name, except that the ruby-crown's song is of the same gushing,

lyrical character as that referred to above. Dr. Brewer was entranced

with the song of one of these tiny minstrels in the woods of New

Brunswick, and thought he had found the author of the strain in the

black-poll warbler. He seems loath to believe that a bird so small as

either of the kinglets could possess such vocal powers. It may indeed

have been the winter wren, but from my own observation I believe the

ruby-crowned kinglet quite capable of such a performance.

But I must leave this part of the subject and hasten on. As to works

on ornithology, Audubon's, though its expense puts it beyond the reach

of the mass of readers, is by far the most full and accurate. His

drawings surpass all others in accuracy and spirit, while his

enthusiasm and devotion to the work he had undertaken have but few

parallels in the history of science. His chapter on the wild goose is

as good as a poem. One readily overlooks his style, which is often

verbose and affected, in consideration of enthusiasm so genuine and

purpose so single.

There has never been a keener eye than Audubon's, though there have

been more discriminative ears. Nuttall, for instance is far more happy

in his descriptions of the songs and notes of birds, and more to be

relied upon. Audubon thinks the song of the Louisiana water-thrush

equal to that of the European nightingale, and, as he had heard both

birds, one would think was prepared to judge. Yet he has, no doubt,

overrated the one and underrated the other. The song of the

water-thrush is very brief, compared with the philomel's, and its

quality is brightness and vivacity, while that of the latter bird, if

the books are to be credited, is melody and harmony. Again, he says

the song of the blue grosbeak resembles the bobolink's, which it does

about as much as the two birds resemble each other in color; one is

black and white and the other is blue. The song of the wood-wagtail,

he says, consists of a "short succession of simple notes beginning

with emphasis and gradually falling." The truth is, they run up the

scale instead of down, beginning low and ending in a shriek.

Yet considering the extent of Audubon's work, the wonder is the errors

are so few. I can at this moment recall but one observation of his,

the contrary of which I have proved to be true. In his account of the

bobolink he makes a point of the fact that, in returning south in the

fall, they do not travel by night as they do when moving north in the

spring. In Washington I have heard their calls as they flew over at

night for four successive autumns. As he devoted the whole of a long

life to the subject, and figured and described over four hundred

species, one feels a real triumph on finding in our common woods a

bird not described in his work. I have seen but two. Walking in the

woods one day in early fall, in the vicinity of West Point, I started

up a thrush that was sitting on the ground. It alighted on a branch a

few yards off, and looked new to me. I thought I had never before seen

so long-legged a thrush. I shot it, and saw that it was a new

acquaintance. Its peculiarities were its broad, square tail; the

length of its legs, which were three and three quarters inches from

the end of the middle toe to the hip-joint; and the deep uniform

olive-brown of the upper parts, and the gray of the lower. It proved

to be the gray-cheeked thrush, named and first described by Professor

Baird. But little seems to be known concerning it, except that it

breeds in the far north, even on the shores of the Arctic Ocean. I

would go a good way to hear its song.

The present season I met with a pair of them near Washington, as

mentioned above. In size this bird approaches the wood thrush, being

larger than either the hermit or the veery; unlike all other species,

no part of its plumage has a tawny or yellowish tinge. The other

specimen was the northern or small water-thrush, cousin-german to the

oven-bird and the half-brother to the Louisiana water-thrush or

wagtail. I found it at the head of the Delaware, where it evidently

had a nest. It usually breeds much further north. It has a strong,

clear warble, which at once suggests the song of its congener. I have

not been able to find any account of this particular species in the

books, though it seems to be well known.

More recent writers and explorers have added to Audubon's list over

three hundred new species, the greater number of which belong to the

northern and western parts of the continent. Audubon's observations

were confined mainly to the Atlantic and Gulf States and the adjacent

islands; hence the Western or Pacific birds were but little known to

him, and are only briefly mentioned in his works.

It is, by the way, a little remarkable how many of the Western birds

seem merely duplicates of the Eastern. Thus, the varied thrush of the

West is our robin, a little differently marked; and the red-shafted

woodpecker is our golden-wing, or high-hole, colored red instead of

yellow. There is also a Western chickadee, a Western chewink, a

Western blue jay, a Western bluebird, a Western song sparrow, Western

grouse, quail, hen-hawk, etc.

One of the most remarkable birds of the West seems to be a species of

skylark, met with on the plains of Dakota, which mounts to the height

of three or four hundred feet, and showers down its ecstatic notes. It

is evidently akin to several of our Eastern species.

A correspondent, writing to me from the country one September, said:

"I have observed recently a new species of bird here. They alight upon

the buildings and fences as well as upon the ground. They are

walkers." In a few days he obtained one and sent me the skin. It

proved to be what I had anticipated, namely the American pipit, or

titlark, a slender brown bird, about the size of the sparrow, which

passes through the States in the fall and spring, to and from its

breeding haunts in the far north. They generally appear by twos and

threes, or in small loose flocks, searching for food on banks and

plowed ground. As they fly up, they show two or three white quills in

the tail, like the vesper sparrow. Flying over, they utter a single

chirp or cry every few rods. They breed in the bleak, moss-covered

rocks of Labrador. It is reported that their eggs have also been found

in Vermont, and I feel quite certain that I saw this bird in the

Adirondack Mountains in the month of August. The male launches into

the air, and gives forth a brief but melodious song, after the manner

of all larks. They are walkers. This is a characteristic of but few of

our land-birds. By far the greater number are hoppers. Note the track

of the common snowbird; the feet are not placed one in front of the

other, as in the track of the crow or partridge, but side and side.

The sparrows, thrushes, warblers, woodpeckers, buntings, etc., are all

hoppers. On the other hand, all aquatic or semi-aquatic birds are

walkers. The plovers and sandpipers and snips run rapidly. Among the

land-birds, the grouse, pigeons, quails, larks and various blackbirds

walk. The swallows walk, also, whenever they use their feet at all,

but very awkwardly. The larks walk with ease and grace. Note the

meadowlarks strutting about all day in the meadows.

Besides being walkers, the larks, or birds allied to the larks, all

sing upon the wing, usually poised or circling in the air, with a

hovering, tremulous flight. The meadowlark occasionally does this in

the early part of the season. At such times its long-drawn note or

whistle becomes a rich, amorous warble.

The bobolink, also, has both characteristics, and, notwithstanding the

difference of form and build, etc., is very suggestive of the English

skylark, as it figures in the books, and is, no doubt, fully its equal

as a songster.

Of our small wood-birds we have three varieties east of the

Mississippi, closely related to each other, which I have already

spoken of, and which walk, and sing, more or less, on the wing, namely

the two species of water-thrush or wagtails, and the oven-bird or

wood-wagtail. The latter is the most common, and few observers of the

birds can have failed to notice its easy, gliding walk. Its other lark

trait, namely singing in the air, seems not to have been observed by

any other naturalist. Yet it is a well-established characteristic, and

may be verified by any person who will spend a half hour in the woods

where this bird abounds on some June afternoon or evening. I hear it

very frequently after sundown, when the ecstatic singer can hardly be

distinguished against the sky. I know of a high, bald-top mountain

where I have sat late in the afternoon and heard them as often as one

every minute. Sometimes the bird would be far below me, sometimes near

at hand; and very frequently the singer would be hovering a hundred

feet above the summit. He would start from the trees on one side of

the open space, reach his climax in the air, and plunge down on the

other side. His descent after the song is finished is very rapid, and

precisely like that of the titlark when it sweeps down from its course

to alight on the ground.

I first verified this observation some years ago. I had long been

familiar with the song, but had only strongly suspected the author of

it, when, as I was walking in the woods one evening, just as the

leaves were putting out, I saw one of these birds but a few rods from

me. I was saying to myself, half audibly, "Come, now, show off, if it

is in you; I have come to the woods expressly to settle this point,"

when it began to ascend, by short hops and flights, through the

branches, uttering a sharp, preliminary chirp. I followed it with my

eye; saw it mount into the air and circle over the woods; and saw it

sweep down again and dive through the trees, almost to the very perch

from which it had started.

As the paramount question in the life of a bird is the question of

food, perhaps the most serious troubles our feathered neighbors

encounter are early in the spring, after the supply of fat with which

Nature stores every corner and by-place of the system, thereby

anticipating the scarcity of food, has been exhausted, and the sudden

and severe changes in the weather which occur at this season make

unusual demands upon their vitality. No doubt many of the earlier

birds die from starvation and exposure at this season. Among a troop

of Canada sparrows which I came upon one March day, all of them

evidently much reduced, one was so feeble that I caught it in my hand.

During the present season, a very severe cold spell the first week in

March drove the bluebirds to seek shelter about the houses and

outbuildings. As night approached, and the winds and the cold

increased, they seemed filled with apprehension and alarm, and in the

outskirts of the city came about the windows and the doors, crept

beneath the blinds, clung to the gutters and beneath the cornice,

flitted from porch to porch, and from house to house, seeking in vain

from some safe retreat from the cold. The street pump, which had a

small opening just over the handle, was an attraction which they could

not resist. And yet they seemed aware of the insecurity of the

position; for no sooner would they stow themselves away into the

interior of the pump, to the number of six or eight, than they would

rush out again, as if apprehensive of some approaching danger. Time

after time the cavity was filled and refilled, with blue and brown

intermingled, and as often emptied. Presently they tarried longer than

usual, when I made a sudden sally and captured three, that found a

warmer and safer lodging for the night in the cellar.

In the fall, birds and fowls of all kinds become very fat. The

squirrels and mice lay by a supply of food in their dens and retreats,

but the birds, to a considerable extent, especially our winter

residents, carry an equivalent in their own systems, in the form of

adipose tissue. I killed a red-shouldered hawk one December, and on

removing the skin found the body completely encased in a coating of

fat one quarter of an inch in thickness. Not a particle of muscle was

visible. This coating not only serves as a protection against the

cold, but supplies the waste of the system when food is scarce or

fails altogether.

The crows at this season are in the same condition. It is estimated

that a crow needs at least half a pound of meat per day, but it is

evident that for weeks and months during the winter and spring they

must subsist on a mere fraction of that amount. I have no doubt that a

crow or hawk, when in his fall condition, would live two weeks without

a morsel of food passing his beak; a domestic fowl will do as much.

One January I unwittingly shut a hen under the door of an outbuilding,

where not a particle of food could be obtained, and where she was

entirely unprotected from the severe cold. When the luckless Dominick

was discovered, about eighteen days afterward, she was brisk and

lively, but fearfully pinched up, and as light as a bunch of feathers.

The slightest wind carried her before it. But by judicious feeding she

was soon restored.

The circumstances of the bluebirds being emboldened by the cold

suggests the fact that the fear of man, which by now seems like an

instinct in the birds, is evidently an acquired trait, and foreign to

them in a state of primitive nature. Every gunner has observed, to his

chagrin, how wild the pigeons become after a few days of firing among

them; and, to his delight, how easy it is to approach near his game in

new or unfrequented woods. Professor Baird [footnote: Then at the head

of the Smithsonian Institution] tells me that a correspondent of

theirs visited a small island in the Pacific Ocean, situated about two

hundred miles off Cape St. Lucas, to procure specimens. The island was

but a few miles in extent, and had probably never been visited half a

dozen times by human beings. The naturalist found the birds and

water-fowls so tame that it was but a waste of ammunition to shoot

them. Fixing a noose on the end of a long stick, he captured them by

putting it over their necks and hauling them to him. In some cases not

even this contrivance was needed. A species of mockingbird in

particular, larger than ours and a splendid songster, made itself so

familiar as to be almost a nuisance, hopping on the table where the

collector was writing, and scattering the pens and paper. Eighteen

species were found, twelve of them peculiar to the island.

Thoreau relates that in the woods of Maine the Canada jay will

sometimes make its meal with the lumbermen, taking the food out of

their hands.

Yet notwithstanding the birds have come to look upon man as their

natural enemy, there can be little doubt that civilization is on the

whole favorable to their increase and perpetuity, especially to the

smaller species. With man comes flies and moths, and insects of all

kinds in greater abundance; new plants and weeds are introduced, and,

with the clearing up of the country, are sowed broadcast over the

land.

The larks and snow buntings that come to us from the north subsist

almost entirely upon the seeds of grasses and plants; and how many of

our more common and abundant species are field-birds, and entire

strangers to deep forests?

In Europe some birds have become almost domesticated, like the house

sparrow; and in our own country the cliff swallow seems to have

entirely abandoned ledges and shelving rocks, as a place to nest, for

the eaves and projections of farm and other outbuildings.

After one has made the acquaintance of most of the land-birds, there

remain the seashore and its treasures. How little one knows of the

aquatic fowls, even after reading carefully the best authorities, was

recently forced home to my mind by the following circumstance: I was

spending a vacation in the interior of New York, when one day a

stranger alighted before the house, and with a cigar box in his hand

approached me as I sat in the doorway. I was about to say that he

would waste his time in recommending his cigars to me, as I never

smoked, when he said that, hearing I knew something about birds, he

had brought me one which had been picked up a few hours before in a

hay-field near the village, and which was stranger to all who had seen

it. As he began to undo the box I expected to see some of our own

rarer birds, perhaps the rose-breasted grosbeak or Bohemian chatterer.

Imagine, then, how I was taken aback when I beheld instead a

swallow-shaped bird, quite as large as a pigeon, with a forked tail,

glossy black above and snow-white beneath. Its parti-webbed feet, and

its long graceful wings, at a glance told that it was a sea-bird; but

as to its name or habitat I must defer my answer till I could get a

peep into Audubon or some collection.

The bird had fallen down exhausted in a meadow, and was picked up just

as the life was leaving its body. The place must have been one hundred

and fifty miles from the sea as the bird flies. As it was the sooty

tern, which inhabits the Florida Keys, its appearance so far north and

so far inland may be considered somewhat remarkable. On removing the

skin I found it terribly emaciated. It had no doubt starved to death,

ruined by too much wing. Another Icarus. Its great power of flight had

made it bold and venturesome, and had carried it so far out of its

range that it starved to death before it could return.

The sooty tern is sometimes called the sea-swallow on account of its

form and the power of flight. It will fly nearly all day at sea,

picking up food from the surface of the water. There are several

species of terns, some of them strikingly beautiful.
