On the west coast of Argyllshire they are found in greater

numbers, and are not so much confined to covers, being found in

open weather scattered through all the sheltered glens where there

is any brushwood or even bracken. On the occurrence of frost,

however, they all gather to the low-lying covers near the sea,

where its influence serves to keep open the springs; and in such

weather very large bags are often made, as they seem to come not

only from the outlying spots above mentioned, but from the inland

districts, where the frost has sealed up every one of their usual

haunts.

RUBICOLA MINOR (Gmelin)

AMERICAN WOODCOCK

HABITS

This mysterious hermit of the alders, this recluse of the boggy

thickets, this wood nymph of crepuscular habits is a common bird and

well distributed in our Eastern States, widely known, but not intimately

known. Its quiet retiring habits do not lead to human intimacy. It may

live almost in our midst unnoticed. Its needs are modest, its habitat is

circumscribed, and it clings with tenacity to its favorite haunts even

when closely encroached upon by civilization. The banks of a stream

running through my place, close to the heart of the city, were once

famous woodcock covers in which the birds persisted long after the

surroundings were built up; and even within recent years I have had a

pair of woodcocks living in the shrubbery along the stream for a week or

two at a time.

Who knows where to look for woodcocks? Their haunts are so varied that

one may not be surprised to find them almost anywhere, especially on

migrations. Flight birds are here to-day and gone to-morrow. Their

favorite resorts are alder thickets along the banks of meandering

streams or spring-fed boggy runs; rich bottom lands or scrubby hollows,

overgrown with willows, maples, alders, and poison sumac; or the scrubby

edges of damp, second-growth woods, mixed with birches; any such place

will suit them where they can find moist soil, not too wet or too sour,

well supplied with earthworms. During the hot, sultry weather of July

and August, the molting season, they seek the seclusion of cool, moist,

leafy woods or dense thickets; or they may resort to the cool hillside

or mountain bogs, fed by cool springs; or, if the weather is very dry,

they may be found in the wet grassy meadows. Woodcocks do not like too

much water and, after heavy rains, they may be driven from their usual

covers to well-drained hillsides, sparsely covered with small birches,

maples, locusts, and cedars. Sometimes they are found on the tops of

mountains; George B. Sennett (1887) saw a pair on the top of Roan

Mountain in North Carolina, at an elevation of 6,000 feet, "in a clump

of balsams; the overflow from numerous springs which had their sources

at this spot formed an open, adjoining marsh of several acres."

Woodcocks often appear in unexpected places, such as city parks, yards,

gardens, orchards, or even lawns. John T. Nichols writes to me:

A neighbor (Mr. W. S. Dana) called for me at about 10 o'clock in

the morning of a sparklingly clear, rather cool summer's day, to

show me a woodcock that was feeding on his lawn, which slopes down

to an almost fresh water arm of Moriches Bay. We found the bird

still busily engaged where he had left it. It was out in the bright

sunlight, crouched, walking about slowly but continuously. It held

its body in an unsteady wavering manner, and was picking and

digging about the roots of the short grass stubble, apparently

obtaining some food too small for us to determine. The piece of

lawn where the bird was operating was low and flat, adjacent to the

edge of the water where protected by a low bulkhead. The ground was

slightly moist, perhaps from seepage, which may have accounted for

its presence. It was remarkably unsuspicious, allowing us to crawl

within 2 or 3 yards, before flying back to alight under the shade

of near-by trees; but was a full-grown bird, strong on the wing.

I have, more than once, seen a woodcock crouching in the short grass

beside a country road, quite unconcerned as I drove past. I have

frequently seen one in my yard about the shrubbery and I remember seeing

my father stand on his front piazza and shoot one that was standing

under an arborvitae hedge. Moist cornfields are often favorite resorts

for woodcocks in summer.

_Spring._--The woodcock is the first of our waders to migrate north and

one of the earliest of all our migrants, coming with the bluebirds and

the robins, as soon as winter has begun to loosen its grip. The date

depends on the weather and is very variable, for the bird must wait for

a thaw to unlock its food supply in the bogs and spring holes. Walter H.

Rich (1907) has known the woodcock to arrive in Maine as early as

February 10, and says that early birds find a living about the big ant

hills, until the alder covers are ready for them.

In Audubon's (1840) time the migration must have been very heavy, for he

says:

At the time when the woodcocks are traveling from the south toward

all parts of the United States, on their way to their breeding

places, these birds, although they migrate singly, follow each

other with such rapidity, that they may be said to arrive in

flocks, the one coming directly in the wake of the other. This is

particularly observable by a person standing on the eastern banks

of the Mississippi or the Ohio, in the evening dusk, from the

middle of March to that of April, when almost every instant there

whizzes past him a woodcock, with a velocity equaling that of our

swiftest birds. See them flying across and low over the broad

stream; the sound produced by the action of their wings reaches

your ear as they approach, and gradually dies away after they have

passed and again entered the woods.

No such flights can be seen to-day, but we occasionally have a

comparatively heavy migration; such a flight occurred in 1923 and is

thus described in some notes from Edward H. Forbush:

The most remarkable occurrence of the past two months was the

prevalence of migrating woodcocks over a large part of southern New

England and along the coastal regions to Nova Scotia. The first

woodcock was reported in Massachusetts the last week in February

and from the first week in March onward woodcocks were noted in

slowly increasing numbers over a large part of New England. From

March 22 to the first week in April the number of these birds

scattered through Connecticut and eastern Massachusetts was

remarkable. At evening one could find them almost anywhere. They

were seen in the most unlikely places even in daylight. They were

in all the towns around Boston and in the suburbs of the city

itself, and west at least to the Connecticut Valley they were even

more numerous in the woods and swamps. In southern New England at

this time a large part of the snow had gone and in going had thawed

the ground so that no frost remained and the woodcocks could find

earthworms almost everywhere. Farther north there was not only

frost in the ground but there was deep snow and the birds could

find no food.

_Courtship._--The woodcock may be found by those who seek him and know

his haunts, but it is only for a short time during the breeding season,

that he comes out into the open and makes himself conspicuous. His

spectacular evening song-flight has been seen by many observers, and

numerous writers have referred to it or described it more or less fully.

William Brewster (1894) has given us the best and most complete account

of it, but it is too long to quote in full here. I prefer to give my own

version of it. The time to look and listen for it is during the laying

and incubation period--say the month of April in Massachusetts, earlier

farther south, even December and January in the Gulf States. The

performance usually begins soon after sunset, as twilight approaches. On

dark nights it ceases about when the afterglow finally disappears in the

western sky; and it begins again in the morning twilight, lasting from

dawn to broad daylight. On moonlight nights it is often continued

through much or all of the night. The woodcock's nest is usually in some

swampy thicket or on the edge of the woods, near an open pasture, field,

or clearing; and here in the nearest open space, preferably on some

knoll or low hillside within hearing of his sitting mate, the male

woodcock entertains her with his thrilling performance. Sometimes, but

not always, he struts around on the ground, with tail erect and spread,

and with bill pointing downwards and resting on his chest. More often he

stands still, or walks about slowly in a normal attitude, producing at

intervals of a few seconds two very different notes--a loud, rasping,

emphatic _zeeip_--which might be mistaken for the note of the nighthawk,

and a soft guttural note, audible at only a short distance, like the

croak of a frog or the cluck of a hen. Suddenly he rises, and flies off

at a rising angle, circling higher and higher, in increasing spirals,

until he looks like a mere speck in the sky, mounting to a height of 200

or 300 feet; during the upward flight he whistles continuously,

twittering musical notes, like _twitter_, _itter_, _itter_, _itter_,

repeated without a break. These notes may be caused by the whistling of

his wings, but it seems to me that they are vocal. Then comes his true

love song--a loud, musical, three-syllable note--sounding to me like

_chicharee_, _chicharee_, _chicharee_ uttered three times with only a

slight interval between the outbursts; this song is given as the bird

flutters downward, circling, zigzagging, and finally volplaning down to

the ground at or near his starting point. He soon begins again on the

_zeeip_ notes and the whole act is repeated again and again. Sometimes

two, or even three, birds may be performing within sight or hearing;

occasionally one is seen to drive another away.

The performance has been similarly described by several others with

slight variations. Mr. Brewster (1894) refers to what I have called the

_zeeip_ note as _paap_ and the soft guttural note as _p'tul_, and says

that--

"Each _paap_ was closely preceded by a _p'tul_, so closely at times that

the two sounds were nearly merged."

He counted the _paaps_ as "uttered consecutively 31, 21, 37, 29, and 28

times."

Describing the action in detail, he says:

At each utterance of the _paap_ the neck was slightly lengthened,

the head was thrown upward and backward (much in the manner of a

least flycatcher's while singing), the bill was opened wide and

raised to a horizontal position, the wings were jerked out from the

body. All these movements were abrupt and convulsive, indicating

considerable muscular effort on the part of the bird. There was

perhaps also a slight twitching of the tail, but this member was

not perceptibly raised or expanded. The return of the several parts

to their respective normal positions was quite as sudden as were

the initial movements. The forward recovery of the head was well

marked. The opening and shutting of the bill strongly suggested

that of a pair of tongs. During the emission of the _paap_ the

throat swelled and its plumage was ruffled, but neither effect was

more marked than with any of our small birds while in the act of

singing.

The mouth opened to such an extent that I could look directly down

the bird's throat, which appeared large enough to admit the end of

one's forefinger. The lateral distension of the mouth was

especially striking.

Referring to the song flight, he says: "Two flights, which I timed from

the start to the finish, lasted, respectively, 57 and 59 seconds, the

song 11 and 12 seconds, respectively." During the flight he followed him

with a glass and "made out distinctly that while singing he alternately

flapped his wings (several times in succession) and held them extended

and motionless."

Francis H. Allen has sent me the following notes on his impression of

the song:

In all that has been written of this wonderful performance of the

woodcock's, I do not remember to have seen any full description of

the song itself; the peeping, or _peenting_, on the ground, with

the alternating water-dropping sounds and the accompaniment of

head-jerking and wing-lifting has been described at length, as well

as the remarkable spiral ascent into the air on whistling wings;

but the character of the actual song, which is uttered at the

summit of the ascent and as the bird comes down, is worth a little

more attention. It begins in a confused series of chipping whistles

which convey the impression of coming from at least three birds at

once. These soon resolve themselves into groups of four to

six--usually four in my experience--descending notes, the groups

alternating with groups of high-pitched wing-whistles. These song

notes vary in sweetness with different individuals, but are often

very clear and musical. Not the least interesting aspect of the

woodcock's evening hymn is the fact that so stolid appearing a bird

should be moved by the fervor of courtship to execute so elaborate

and exciting a performance. The excitement attending the affair as

far as the spectator, or rather listener, is concerned lies to

great extent in the wing whistling. When the woodcock first rises,

the whistle is comparatively low, but as he mounts, the pitch rises

and the rapidity of production increases. It is a steady succession

of very short whistling notes for some time, but, when the bird and

the whistle both reach their height, it comes in short groups of

extremely rapid whistles alternating with brief intervals of

motionless wings, as if the performer were breathless with

excitement and effort and could not sustain his flight for long at

a time. This is the effect, I mean. Probably the bird finds it easy

enough, for he makes his flight at comparatively short intervals

and during his periods of rest he is hard at work producing his

harsh and unmusical nighthawk-like _peent_ notes which involve a

deal of muscular effort.

Lynds Jones (1909) says that "the bird floats downward by a crooked

path, the while calling in coaxing tones _p chuck tuck cuck oo_, _p

chuck tuck cuckoo_, uttered more slowly at first, regularly increasing

in rapidity until the notes are almost a wheedling call." Isador S.

Trostler (1893) describes a feature of the courtship which I have not

seen mentioned elsewhere; he writes:

The birds often play in a very droll manner, running round and

round each other in a small circle, their feathers ruffled, their

wings lifted, and their long bills pointing nearly directly upward,

with their heads resting on their backs.

Sometimes they will hop on one foot, holding the other at a queer

angle, as if it had been broken or hurt. The male bird utters a

low indescribable sound during all the playing, and the sight of

these queer antics is worth more than to have seen Modjeska or

Barrett in their celebrated plays.

_Nesting._--The nesting sites of the woodcock are almost as varied as

its haunts at other times. I have never known how or where to look for

its nest; in over 40 years of field work I have seen but one nest with

eggs. That was shown to me by Mrs. Mary M. Kaan, in Chestnut Hill,

Massachusetts, on June 2, 1924. It was located where I should never have

thought of looking for one, in an open, rocky hollow in open woods,

within 50 feet of a bridle path on one side and about the same distance

from a swampy ravine and brook on the other side. The nest was on a

little hummock, surrounded by herbage about a foot high; it was a mere

hollow in the ground lined with dead leaves. Although it was in fairly

plain sight, it was a long time before I could see the sitting bird,

even when it was pointed out to me. The bird sat like a rock, as this

species usually does, while I took a series of photographs of it, moving

gradually nearer. I even removed two leaves which were resting on her

bill, and Mrs. Kaan stroked her on the back before she left. The nest

held only three eggs, which were probably a second laying.

The usual nesting sites are in alder runs, swampy thickets, brushy

corners in pastures, or in underbrush or tall weeds along the edges of

woods. Woodcocks are early breeders and it sometimes happens that nests

are buried under late falls of snow; in such cases the birds continue to

sit as long as it is possible to do so. The nest is often placed at the

foot of a small tree or bush, occasionally beside a log or stump or even

under fallen brush. An abundance of fallen leaves seems to be an

essential requirement, of which the nest is usually made and among which

the bird relies on its protective coloration for concealment; but its

big black eyes sometimes reveal it.

L. Whitney Watkins (1894) found a nest near Manchester, Michigan, in

heavy timber, and within a few feet of a reed-bordered, springy spot, it

was within 2 feet of an ovenbird's nest. Another nest he describes as

follows:

The old bird, curiously enough, had selected for her nesting site

an open spot where some fallen boughs had partially decayed, and

within 5 feet of a picket fence enclosing an open pasture field.

Opposite her on the other side, were ash, elm, oak, and other

trees, of no considerable size, and round about were many

frost-dried stems of aster and goldenrod, interspersed with the

fallen leaves of the previous summer. Little of green was near.

E. G. Taber (1904) found a nest that was situated in a swampy corner of

a field planted with corn, only 6 feet from the open, on a slightly

raised portion of the ground. This corner was overgrown with black ash,

soft maple, tag alders, and ferns, mingled with poison ivy. Mr. Brewster

(1925) describes two, of several, nests found near Umbagog Lake, Maine,

as follows:

One, containing four eggs, incubated perhaps as many days, was in

the face of a low mound partially overarched by balsam shrubs

surrounded on every side by pools of water, and some 80 yards from

the lake shore near the middle of swampy, second-growth woods made

up chiefly of aspen, red cherry, and yellow birch trees, 20 or 30

feet in height, beneath which grew alders rather abundantly. The

female woodcock flew up from her eggs at least 15 feet in advance

of me, and whistling faintly soared off over the tree tops to be

seen no more. I flushed a male about 50 yards from this nest.

Of the other he says:

It was at the edge of a little fern-grown opening, on a mound

covered with brakes flattened and bleached by winter snows, beneath

a balsam scarce 2 feet high, and not dense enough to afford much

concealment for the eggs which, indeed, caught my eye when I was 15

feet away, there being no bird on them.

Mr. Trostler (1893) writes:

Finding a nest one day, I disturbed the setting bird three times,

and again four times on the next day, and on the morning of the

third day I found that the birds had removed the eggs during the

night and placed them in a new nest about 8 feet away, where I

found the eggs. I had marked the eggs to avoid any mistake. The

second nest was a mere hollow in the mossy ground, and was in the

middle of an open place in tall marsh grass, while the first was

neatly cupped and lined with the above-mentioned vegetable down.

Another singular habit of the woodcock that I have never seen noted

is that of both birds setting upon the nest in wet or cold weather.

In doing this they huddle very close together and face in opposite

directions, and I have always noted that they have their heads

thrown back and their bills elevated to an angle of about

forty-five degrees.

Mr. Nichols writes to me:

On Long Island there is a favorite nesting station for woodcock,

where the woodland gives place to broad fields, separated by narrow

stands of big trees with a sparse tangled undergrowth of shrubbery

and cat-brier, and where here and there a short fresh-water creek

extends inland from the not distant bay.

Several writers have stated or implied that the woodcock raises two

broods in a season. This would be an exception to the rule among waders.

I believe that it normally nests early and that the late nests are

merely second attempts at raising a brood, where the first nest has been

destroyed.

An interesting case of nest-protecting display is thus described by Dr.

Robert Cushman Murphy (1926):

She (assuming that it was the female) would allow us to come within

a few feet before leaving her well-concealed position. Then she

would spring from the nest, pitch on the ground close by, and,

standing with the tail toward us, would raise and spread it so as

to show to full advantage the double row of glistening white spots

at the ends of the rectrices and under coverts. Next, flashing this

striking banner slowly, she would move off among the trees in the

attitude of a strutting turkey cock, stopping when we refused to

follow, and then tripping ahead for a few steps, all the while

bleating softly. The effect was astonishing; the ordinary low

visibility of a woodcock against the forest floor no longer held,

for the spotted fan of the tail had become a most conspicuous and

arresting mark.

_Eggs._--The American woodcock lays four eggs, sometimes only three, and

rarely five. They vary in shape from ovate to rounded ovate and have a

moderate gloss. The ordinary ground colors vary from "pinkish buff" to

"cartridge buff" and in certain brown types from "pinkish buff" to

"cinnamon." They are usually rather sparingly and more or less evenly

marked with small spots, but sometimes these spots are concentrated

about the larger end. In the lighter types, which are the most common,

there are often many large blotches of light shades of "vinaceous drab"

or "brownish drab"; these are conspicuous and often predominate. Mixed

with them are numerous small spots of light browns, "cinnamon," "clay

color," or "tawny olive." In the brown types these spots are in richer

browns, "hazel," "russet," or "cinnamon brown," with the drab spots less

conspicuous. The measurements of 53 eggs, in the United States National

Museum, average 38 by 29 millimeters; the eggs showing the four

extremes measure =41= by =30= and =35= by =27.5= millimeters.
