The flicker is the largest of our common American woodpeckers, being

somewhat longer and stouter than the robin. It is known, by sight

at least, to almost every one who notices birds at all, and perhaps

for this reason it has received an unusual number of popular names.

“Golden-winged woodpecker,” which is probably the best known of these,

comes from the fact that the bird’s wings are yellow on the under side.

“Harry Wicket,” “Highhole,”--because its nest is sometimes pretty far

above the ground,--“Yellowhammer,” and “Pigeon-woodpecker” are also

among its more familiar nicknames.

Unlike other birds of its family, the flicker passes much of its time

on the ground, where it hops awkwardly about, feeding upon insects,

especially upon ants. As you come near it, while it is thus engaged, it

rises with a peculiar purring sound, and as it flies from you it shows

a broad white patch on its rump--the lower back, above the root of

the tail. Every one who has ever walked much over grassy fields must

have seen the bird and been struck by this conspicuous light mark. He

must have noticed, too, the bird’s peculiar up-and-down, “jumping”

manner of flight, by which it goes swooping across the country in long

undulations or waves.

The flicker’s general color is brown, with spottings and streakings

of black, and more or less of violet or lilac shading. On the back of

its neck it wears a band of bright scarlet, and across its breast is a

conspicuous black crescent.

It is fond of old apple orchards, and often makes its nest in a

decaying trunk. In some places, near the seashore, especially,--where

it is commoner than elsewhere in winter, and where large trees are

scarce,--it makes enemies by its habit of drilling holes in barns and

even in churches. I remember a meeting-house on Cape Cod which had a

good number of such holes in its front wall--or rather it had the scars

of such holes, for they had been covered with patches of tin. That was

a case where going to church might be called a bad habit.

In fall and winter, if not at other seasons, the flicker feeds largely

upon berries. In years when the poison ivy bears a good crop, I am

pretty sure to find two or three flickers all winter long about a

certain farm, the stone walls of which are overrun with this handsome

but unwholesome vine, although it is hard to imagine that the dry,

stony fruit should yield much in the way of nourishment, even to a

woodpecker.

As spring comes on, the flicker becomes numerous and very noisy. His

best-known vocal effort is a prolonged _hi-hi-hi_, very loud and

ringing, and kept up until the listener wonders where the author of it

gets his wind. This, I think, is the bird’s substitute for a song. He

has at all times a loud, unmusical _yawp_,--a signal, I suppose,--and

in the mating season especially he utters a very affectionate,

conversational _wicker_ or _flicker_. Every country boy should be

familiar with these three notes.

_1. Male. 2. Females_]

But besides being a vocalist,--we can hardly call him a singer,--the

flicker is a player upon instruments. He is a great drummer; and if

any one imagines that woodpeckers do not enjoy the sound of their

own music, he should watch a flicker drumming with his long bill on

a battered tin pan in the middle of a pasture. Morning after morning

I have seen one thus engaged, drumming lustily, and then cocking his

head to listen for an answer; and Paderewski at his daily practice upon

the piano could not have looked more in earnest. At other times the

flicker contents himself with a piece of resonant loose bark or a dry

limb.

One proof that this drumming--which is indulged in by woodpeckers

generally--is a true musical performance, and not a mere drilling for

grubs, is the fact that we never hear it in winter. It begins as the

weather grows mild, and is as much a sign of spring as the peeping of

the little tree-frogs--hylas--in the meadow.

The flicker’s nest, as I have said, is built in a hole in a tree, often

an apple-tree. Very noisy in his natural disposition, he keeps a wise

silence while near the spot where his mate is sitting, and will rear

a brood under the orchard-owner’s nose without betraying himself. The

young birds are fed from the parent’s crop, as young pigeons and young

hummingbirds are. The old bird thrusts its bill down the throat of

the nestling and gives it a meal of partially digested food by what

scientific people call a process of regurgitation. Farmers’ boys, who

have watched pigeons feeding their squabs, will know precisely what is

meant.

XVII

THE BITTERN

It was a great day for me when I first heard the so-called booming of

the bittern. For more than ten years I had devoted the principal part

of my spare hours to the study of birds, but though I had taken many

an evening walk near the most promising meadows in my neighborhood, I

could never hear those mysterious pumping or stake-driving noises of

which I had read with so much interest, especially in the writings of

Thoreau.

The truth was, as I have since assured myself, that this representative

of the heron family was not a resident within the limits of my everyday

rambles, none of the meadows thereabout being extensive and secluded

enough to suit his whim.

There came a day, however, when with a friend I made an afternoon

excursion to Wayland, Massachusetts, on purpose to form the

stake-driver’s acquaintance. We walked up the railway track across

the river toward Sudbury, and were hardly seated on the edge of the

meadow, facing the beautiful Nobscot Hill, before my comrade said,

“Hark! There he is!”

Yes, that certainly was the very sound--an old-fashioned wooden pump at

work in the meadow.

We listened intently for perhaps half a dozen times; then I proposed

going further up the track to get the notes at shorter range, and

possibly--who could tell what unheard-of thing might happen?--to obtain

a sight of the bird. We advanced cautiously, though as we were on the

track, six feet or more above the level of the meadow, there was no

chance of concealment, and the bittern went on with his performance.

Meanwhile we maintained a sharp lookout, and presently I descried

a narrow brown object standing upright amidst the grass--a stick,

perhaps. I lifted my opera-glass and spoke quickly to my friend: “I see

him!”

“Where?” he asked; and when I lowered my glass and gave him the bird’s

bearings as related to the remains of an old hayrick not far off, he

said, “Why, I saw that, but took it for a stick.”

“Yes, but see the eye,” I answered.

Within half a minute the bird suddenly threw his head forward and

commenced pumping. This was good luck indeed,--that I should surprise

my very first bittern in his famous act, a thing which better men than

I, after years of familiarity with the bird, had never once succeeded

in accomplishing. Who says that Fortune does not sometimes favor the

fresh hand?

The fellow repeated the operation three times, and between whiles moved

stealthily through the grass toward the leavings of the haycock before

mentioned.

When he reached the hay, we held our breath. Would he actually mount

it? Yes, that was undoubtedly his intention; but he meant to do it in

such a way that no mortal eye should see him. All the time glancing

furtively to left and right, as if the grass were full of enemies, he

put one foot before the other with almost inconceivable slowness,--as

the hour hand turns on the clock’s face. It was an admirable display

of an art which this race of frog, mouse, and insect catchers has

cultivated for untold generations--an art on which its livelihood

depends, the art of invisible motion.

There was no resisting the ludicrousness of his manner. He was in full

view, but so long as he kept still he seemed to think himself quite

safe from detection. Like the hand of the clock, however, if he was

slow he was sure, and in time he was fairly out of the grass, standing

in plain sight upon his hay platform.

Once in position he fell to pumping in earnest, and kept it up for more

than an hour, while two enthusiasts sat upon the railway embankment,

twelve or thirteen rods distant, with opera-glasses and note-books,

scrutinizing his every motion, and felicitating themselves again and

again on seeing thus plainly what so few had ever seen at all. What

would Thoreau have given for such an opportunity?

“The stake-driver is at it in his favorite meadow,” he writes in

his journal, in 1852. “I followed the sound, and at last got within

two rods, it seeming always to recede, and drawing you, like a

will-o’-the-wisp, farther away into the meadows. When thus near, I

heard some lower sounds at the beginning like striking on a stump or a

stake, a dry, hard sound, and then followed the gurgling, pumping notes

fit to come from a meadow.

“This was just within the blueberry and other bushes, and when the bird

flew up, alarmed, I went to the place, but could see no water, which

makes me doubt if water is necessary to it in making the sound. Perhaps

it thrusts its bill so deep as to reach water where it is dry on the

surface.”

This notion that water is employed in the production of the bittern’s

notes has been generally entertained. The notes themselves are of a

character to suggest such an hypothesis, and at least one witness has

borne circumstantial testimony to its truth. In Thoreau’s essay on the

“Natural History of Massachusetts,” he says:--

“On one occasion, the bird has been seen by one of my neighbors to

thrust its bill into the water, and suck up as much as it could hold;

then, raising its head, it pumped it out again with four or five heaves

of the neck, throwing it two or three feet, and making the sound each

time.”

Similar statements have been made as to the corresponding notes of

the European bittern. None of our systematic writers upon American

ornithology have ever witnessed the performance, as far as appears, and

being too honest to draw upon their imaginations, they have left the

matter a mystery. Now, on this auspicious May afternoon, if we learned

nothing else, we could at all events make quite sure whether or not the

bittern did really spout water from his beak.

My readers will have guessed already that our bird, at least, did

nothing of the sort. His bill was never within reach of water. The

operation is a queer one, hard to describe.

The bittern has been standing motionless, perhaps in the humpbacked

attitude in which the artists, following Audubon’s plate, have commonly

represented him; or quite as likely, he has been making a stick or a

soldier of himself, standing bolt upright at full stretch, his long

neck and bill pointed straight at the zenith.

Suddenly he lowers his head, and instantly raises it again and throws

it forward with a quick, convulsive jerk. This movement is attended

by an opening and shutting of the bill, which in turn is accompanied

by a sound which has been well compared to a violent hiccough. The

hiccough--with which, I think, the click of the big mandibles may

sometimes be heard--is repeated a few times, each time a little louder

than before; and then succeed the real pumping or stake-driving noises.

These are in sets of three syllables each, of which the first syllable

is the longest, and somewhat separated from the others. The accent is

strongly upon the middle syllable, and the whole, as oftenest heard, is

an exact reproduction of the sound of a wooden pump, as I have already

said, the voice having that peculiar hollow quality which is produced,

not by the flow of the water, but by the suction of the air in the tube

when the pump begins to work.

But the looker-on is likely to be quite as much impressed by what he

sees as by what he hears. During the whole performance, but especially

during the latter part of it, the bird is engaged in the most violent

contortions, suggestive of nothing but a patient suffering from

uncontrollable nausea. Moreover, as soon as the preliminary hiccoughs

begin, the lower throat or breast is seen to be swelling; the

dilatation grows larger and larger till the pumping is well under way,

and so far as my companion and I could detect, does not subside in the

least until the noises have ceased altogether.

How are the unique, outlandish notes produced? I cannot profess to

know. Our opinion was that the bird swallowed air into his gullet,

gulping it down with each snap of the beak. To all appearance it was

necessary for him to inflate the crop in this way before he could pump,

or boom. As to how much of the grand booming was connected with the

swallowing of the air, and how much, if any, with the expulsion of it,

my friend and I did not agree, and of course neither of us could do

more than guess.

I made some experiments afterwards, by way of imitating the noises;

and these experiments, together with the fact that the grand booming

seemed to be really nothing more than a development of the preliminary

hiccoughs, and the further fact that the swelling of the breast did not

go down gradually during the course of the performance, but suddenly at

the close,--all these incline me to believe that the notes are mainly

if not entirely caused by the inhalation or swallowing of the air; and

I am somewhat strengthened in this opinion by perceiving that when

a man takes air into his stomach the act is attended by a sound not

altogether unlike the bittern’s note in quality, while the expulsion of

it gives rise to noises of an entirely dissimilar character.

That the sounds in question were not made entirely by any ordinary

action of the vocal organs was the decided opinion of both my friend

and myself.

As I have said, we watched the performance for more than an hour. We

were sitting squarely upon the track, and once were compelled to get

up to let a train pass; but the bittern evidently paid no attention to

matters on the railway, being well used to thunder in that direction,

and stood his ground without wincing.

When he had pumped long enough,--and the operation surely looked like

pretty hard work,--he suddenly took wing and flew a little distance

down the meadow. The moment he dropped into the grass he pumped, and

on making another flight he again pumped immediately upon coming to

the ground. This trick, which surprised me not a little in view of

the severe exertion required, is perhaps akin to the habit of smaller

birds, who in seasons of excitement will very often break into song at

the moment of striking a perch.

As we came down the track on our way back to the station, three

bitterns were in the air at once, while a fourth was booming on the

opposite side of the road. One of the flying birds persistently dangled

his legs instead of drawing them up in the usual fashion and letting

the feet stick out behind, parallel with the tail. Probably he was

“showing off,” as is the custom of many birds during the season of

mating.

Our bird across the road, by the bye, was not pumping, but driving a

stake. The middle syllable was truly a mighty whack with a mallet on

the head of a post, so that I could easily enough credit Mr. Samuels’s

statement that he once followed the sound for half a mile, expecting to

find a farmer setting a fence.

In the midst of the hurly-burly we saw a boy coming toward us on the

track.

“Let’s ask him about it,” said my companion.

So, with an air of inquisitive ignorance, he stopped the fellow, and

inquired, “Do you know what it is we hear making that curious noise off

there in the meadow?”

The boy evidently took us for a pair of ignoramuses from the city.

“I guess it’s a frog,” he answered. But when the sounds were repeated

he shook his head and confessed honestly that he didn’t know what made

them.

It was too bad, I thought, that he did not stick to his frog theory.

It would have made so much better a story! He appeared to feel no

curiosity about the matter, and we allowed him to pass on unenlightened.

Not all Wayland people are thus poorly informed, however, and we

shortly learned, to our considerable satisfaction, that they have a

most felicitous local name for the bird. They call him “plum-pudd’n’,”

which is exactly what he himself says, only that his _u_ is in both

words somewhat long, like the vowel in “full.” To get the true effect

of the words they should be spoken with the lips nearly closed, and in

a deep voice.

A few days after this excursion I found a bittern in a large wet meadow

somewhat nearer home. At the nearest he was a long way off, and as I

went farther and farther away from him, I remarked the very unexpected

fact that the last syllable to be lost was not the second, which bears

so sharp an accent, but the long first syllable. It seemed contrary to

reason, but such was unquestionably the truth, and later experiments

confirmed it.

This was in the spring of 1888. In May of the next year, if all went

well, we would see the show again. So we said to each other; but a

veteran ornithologist remarked that we should probably be a good many

years older before we had another such piece of good fortune.

It is a fact familiar to all naturalists, however, that when you have

once found a new plant, or a new bird, or a new nest, the experience is

likely to be soon repeated. You may have spent a dozen years in a vain

search, but now, for some reason, the difficult has all at once become

easy, and almost before you can believe your eyes the rarity has grown

to be a drug in the market. Something like this proved to be true of

the bittern’s boom.

On the afternoon of the 2d of May, 1889, I went to one of my favorite

resorts, a large cat-tail swamp surrounded by woods. My particular

errand was to see whether the least bittern had arrived,--a much

smaller, and in this part of the country, at least, a much less common

bird than his relative of whose vocal accomplishments I am here

treating.

I threw myself down upon the cliff overhanging the edge of the swamp,

to listen for the desired _coo-coo-coo-coo_, and had barely made myself

comfortable when I heard the _plum-pudd’n’_ of the bittern himself,

proceeding, as it seemed, from the reeds directly at my feet. Further

listening satisfied me that the fellow was not far from the end of a

rocky peninsula which juts into the swamp just at this point.

I slipped down the cliff as quietly as possible, picked my way across

the narrow neck leading to the main peninsula, and by keeping behind

rocks and trees managed to reach the very tip without disturbing

the bird. Here I posted myself among the thick trees, and awaited

a repetition of the boom. It was not long in coming, and plainly

proceeded from a bunch of flags just across a little stretch of clear

water.

I looked and looked, while the bittern continued to pump at rather

protracted intervals; but I could see nothing whatever, till presto!

there the creature stood in plain sight.

Whether he had moved into view, or had all the time been visible, I

cannot tell. He soon pumped again, and then again, for perhaps six

times. Then he stalked away out of sight, and I heard nothing more. He

was much nearer than last year’s bird had been, but was still a pumper,

not a stake-driver, and his action was in all respects the same as I

had before witnessed.

There had been no bittern in this swamp the season previous, nor did

any breed here this summer. I visited the place too often for him to

have escaped my notice, had he been present. This bird, then, was a

migrant, and his booming was of interest as showing that the bittern,

like the song-birds, does not wait to get into summer quarters before

beginning to rehearse his love music.

Two days after this my companion of the year before went with me again

to Wayland, and, not to prolong a long story, we sat again upon the

railway and watched a bittern pump for more than an hour. This time, to

be sure, he was partially concealed by the grass, besides being farther

away than we could have wished.

It was curious, and illustrated strikingly the utility of the bird’s

habit of standing motionless, that my friend, who is certainly as

sharp-eyed an observer as I have ever known, was once more completely

taken in. As luck would have it, I caught sight of the bird first, and

when I pointed him out to the other man he replied, “Why, of course I

saw that, but it never occurred to me but that it was a stake.”

We returned from this excursion fairly well convinced that in the early

part of the season, while the grass is still short, one may hope to

see a bittern pump almost any day, if he will go to a suitable meadow

which has a railroad running through it. The track answers a double

purpose: it gives the observer an outlook, such as cannot be obtained

from a boat, and furthermore, the birds are quite unsuspicious of

things on the track, while the presence of a man in the grass or on the

river would almost inevitably attract their attention.

XVIII

BIRDS FOR EVERYBODY

Some birds belong exclusively to specialists. They are so rare, or

their manner of life is so seclusive, that people in general can never

be expected to know them except from books. The latest list of the

birds of Massachusetts includes about three hundred and fifty species

and sub-species. Of these, seventy-five or more are so foreign to this

part of the country as to have appeared here only by accident, while

many others are so excessively rare that no individual observer can

count upon seeing them, however close a lookout he may keep. Other

species are present in goodly numbers, but only in certain portions of

the State; and still others, though generally distributed and fairly

numerous, live habitually in almost impenetrable swamps or in deep

forests, and of necessity are seen only by those who make it their

business to look for them.

It is something for which busy men and women may well be thankful,

therefore, that so many of the most pleasing, or otherwise

interesting, of all our birds are among those which may be called

birds for everybody. Such are the robin, the bluebird, the Baltimore

oriole,--or golden robin,--the blue jay, the crow, and the chickadee.

Of all these we may say that they are common; they come in every one’s

way, and, what is still more to the point, they cannot be mistaken for

anything else. Others are equally common, and are easily enough seen,

but their identity is not so much a matter of course.

The song sparrow, for example, is abundant in Massachusetts from the

middle of March to the end of October. Outside of the forest it is

almost ubiquitous; it sings beautifully and with the utmost freedom; it

ought, one would say, to be universally known. But it is _a_ sparrow,

not _the_ sparrow. In other words, it is only one of many, and so,

common as it is, and freely as it sings (it is to be heard in every

garden and by every roadside in the latter half of March, when few

other birds are in tune), it passes unrecognized by the generality

of people. They read in books of song sparrows, chipping sparrows,

field sparrows, tree sparrows, swamp sparrows, vesper sparrows,

white-throated sparrows, fox sparrows, yellow-winged sparrows, savanna

sparrows, and the like, and when they see any little mottled brown

bird, they say, “Oh, it’s a sparrow,” and seek to know nothing more.

The family of warblers--among the loveliest of all birds--are in

a still worse case, and much the same may be said of swallows and

blackbirds, thrushes and vireos. The number of species and their

perplexing similarity, which are such an attraction to the student,

prove an effectual bar to those who have time and money for newspapers

and novels, but can spare neither for a manual of local ornithology.
