CHAPTER II

The Passenger Pigeon

(_Columba Migratoria_)

From "American Ornithology," by Alexander Wilson

This remarkable bird merits a distinguished place in the annals of our

feathered tribes--a claim to which I shall endeavor to do justice;

and, though it would be impossible, in the bounds allotted to this

account, to relate all I have seen and heard of this species, yet no

circumstance shall be omitted with which I am acquainted (however

extraordinary some of these may appear) that may tend to illustrate its

history.

The wild pigeon of the United States inhabits a wide and extensive

region of North America, on this side of the Great Stony Mountains,

beyond which, to the westward, I have not heard of their being seen.

According to Mr. Hutchins, they abound in the country around Hudson's

Bay, where they usually remain as late as December, feeding, when the

ground is covered with snow, on the buds of the juniper. They spread

over the whole of Canada; were seen by Captain Lewis and his party near

the Great Falls of the Missouri, upwards of two thousand five hundred

miles from its mouth, reckoning the meanderings of the river; were also

met with in the interior of Louisiana by Colonel Pike; and extend their

range as far south as the Gulf of Mexico, occasionally visiting or

breeding in almost every quarter of the United States.

But the most remarkable characteristic of these birds is their

associating together, both in their migrations, and also during the

period of incubation, in such prodigious numbers, as almost to surpass

belief; and which has no parallel among any other of the feathered

tribes on the face of the earth, with which all naturalists are

acquainted. These migrations appear to be undertaken rather in quest

of food, than merely to avoid the cold of the climate, since we find

them lingering in the northern regions, around Hudson's Bay, so late

as December; and since their appearance is so casual and irregular,

sometimes not visiting certain districts for several years in any

considerable numbers, while at other times they are innumerable. I

have witnessed these migrations in the Genesee country, often in

Pennsylvania, and also in various parts of Virginia, with amazement;

but all that I had then seen of them were mere straggling parties,

when compared with the congregated millions which I have since beheld

in our Western forests, in the States of Ohio, Kentucky, and the

Indiana territory. These fertile and extensive regions abound with

the nutritious beechnut, which constitutes the chief food of the

wild pigeon. In seasons when these nuts are abundant, corresponding

multitudes of pigeons may be confidently expected. It sometimes happens

that, having consumed the whole produce of the beech trees, in an

extensive district, they discover another, at the distance perhaps of

sixty or eighty miles, to which they regularly repair every morning,

and return as regularly in the course of the day, or in the evening,

to their place of general rendezvous, or as it is usually called, the

roosting place. These roosting places are always in the woods, and

sometimes occupy a large extent of forest. When they have frequented

one of these places for some time the appearance it exhibits is

surprising. The ground is covered to the depth of several inches with

their dung; all the tender grass and underwood destroyed; the surface

strewed with large limbs of trees, broken down by the weight of the

birds clustering one above another; and the trees themselves, for

thousands of acres, killed as completely as if girdled with an ax.

The marks of this desolation remain for many years on the spot; and

numerous places could be pointed out, where, for several years after,

scarcely a single vegetable made its appearance.

When these roosts are first discovered, the inhabitants, from

considerable distances, visit them in the night with guns, clubs, long

poles, pots of sulphur, and various other engines of destruction. In

a few hours they fill many sacks, and load their horses with them.

By the Indians, a pigeon roost, or breeding place, is considered an

important source of national profit and dependence for the season; and

all their active ingenuity is exercised on the occasion. The breeding

place differs from the former in its greater extent. In the western

countries above mentioned, these are generally in beech woods, and

often extend, in nearly a straight line across the country for a great

way. Not far from Shelbyville, in the State of Kentucky, about five

years ago, there was one of these breeding places, which stretched

through the woods in nearly a north and south direction; was several

miles in breadth, and was said to be upwards of forty miles in extent!

In this tract almost every tree was furnished with nests, wherever

the branches could accommodate them. The pigeons made their first

appearance there about the 10th of April, and left it altogether, with

their young, before the 29th of May.

As soon as the young were fully grown, and before they left the nests,

numerous parties of the inhabitants from all parts of the adjacent

country came with wagons, axes, beds, cooking utensils, many of them

accompanied by the greater part of their families, and encamped for

several days at this immense nursery. Several of them informed me that

the noise in the woods was so great as to terrify their horses, and

that it was difficult for one person to hear another speak without

bawling in his ear. The ground was strewed with broken limbs of trees,

eggs, and young squab pigeons, which had been precipitated from above,

and on which herds of hogs were fattening. Hawks, buzzards, and eagles

were sailing about in great numbers, and seizing the squabs from

their nests at pleasure; while from twenty feet upwards to the tops

of the trees the view through the woods presented a perpetual tumult

of crowding and fluttering multitudes of pigeons, their wings roaring

like thunder, mingled with the frequent crash of falling timber; for

now the ax-men were at work cutting down those trees that seemed to be

most crowded with nests, and contrived to fell them in such a manner

that, in their descent, they might bring down several others; by which

means the falling of one large tree sometimes produced two hundred

squabs, little inferior in size to the old ones, and almost one mass

of fat. On some single trees upwards of one hundred nests were found,

each containing _one_ young only; a circumstance in the history of

this bird not generally known to naturalists. It was dangerous to walk

under these flying and fluttering millions, from the frequent fall of

large branches, broken down by the weight of the multitudes above,

and which, in their descent, often destroyed numbers of the birds

themselves; while the clothes of those engaged in traversing the woods

were completely covered with the excrements of the pigeons.

These circumstances were related to me by many of the most respectable

part of the community in that quarter, and were confirmed, in part, by

what I myself witnessed. I passed for several miles through this same

breeding place, where every tree was spotted with nests, the remains of

those above described. In many instances I counted upwards of ninety

nests on a single tree, but the pigeons had abandoned this place for

another, sixty or eighty miles off towards Green River, where they

were said at that time to be equally numerous. From the great numbers

that were constantly passing overhead to or from that quarter, I had

no doubt of the truth of this statement. The mast had been chiefly

consumed in Kentucky, and the pigeons, every morning a little before

sunrise, set out for the Indiana territory, the nearest part of which

was about sixty miles distant. Many of these returned before ten

o'clock, and the great body generally appeared on their return a little

after noon.

I had left the public road to visit the remains of the breeding place

near Shelbyville, and was traversing the woods with my gun, on my

way to Frankfort, when, about one o'clock, the pigeons, which I had

observed flying the greater part of the morning northerly, began to

return in such immense numbers as I never before had witnessed. Coming

to an opening by the side of a creek called the Benson, where I had a

more uninterrupted view, I was astonished at their appearance. They

were flying with great steadiness and rapidity at a height beyond

gunshot in several strata deep, and so close together that could shot

have reached them one discharge could not have failed of bringing down

several individuals. From right to left, far as the eye could reach,

the breadth of this vast procession extended, seeming everywhere

equally crowded. Curious to determine how long this appearance would

continue, I took out my watch to note the time, and sat down to,

observe them. It was then half-past one. I sat for more than an hour,

but, instead of a diminution of this prodigious procession, it seemed

rather to increase both in numbers and rapidity, and, anxious to reach

Frankfort before night, I rose and went on. About four o'clock in

the afternoon I crossed the Kentucky River at the town of Frankfort,

at which time the living torrent above my head seemed as numerous

and as extensive as ever. Long after this I observed them in large

bodies that continued to pass for six or eight minutes, and these

again were followed by other detached bodies, all moving in the same

southeast direction, till after six in the evening. The great breadth

of front which this mighty multitude preserved would seem to intimate

a corresponding breadth of their breeding place, which, by several

gentlemen who had lately passed through part of it, was stated to me

at several miles. It was said to be in Green County, and that the

young began to fly about the middle of March. On the seventeenth of

April, forty-nine miles beyond Danville, and not far from Green River,

I crossed this same breeding place, where the nests, for more than

three miles, spotted every tree; the leaves not being yet out I had a

fair prospect of them, and was really astonished at their numbers. A

few bodies of pigeons lingered yet in different parts of the woods, the

roaring of whose wings were heard in various quarters around me.

All accounts agree in stating that each nest contains only one young

squab. These are so extremely fat that the Indians, and many of the

whites, are accustomed to melt down the fat for domestic purposes as a

substitute for butter and lard. At the time they leave the nest they

are nearly as heavy as the old ones, but become much leaner after they

are turned out to shift for themselves.

It is universally asserted in the western countries that the pigeons,

though they have only one young at a time, breed thrice, and sometimes

four times in the same season; the circumstances already mentioned

render this highly probable. It is also worthy of observation that

this takes place during the period when acorns, beechnuts, etc., are

scattered about in the greatest abundance and mellowed by the frost.

But they are not confined to these alone; buckwheat, hempseed, Indian

corn, hollyberries, hackberries, huckleberries, and many others furnish

them with abundance at almost all seasons. The acorns of the live

oak are also eagerly sought after by these birds, and rice has been

frequently found in individuals killed many hundred miles to the

northward of the nearest rice plantation. The vast quantity of mast

which these multitudes consume is a serious loss to the bears, pigs,

squirrels, and other dependents on the fruits of the forest. I have

taken from the crop of a single wild pigeon a good handful of the

kernels of beechnuts, intermixed with acorns and chestnuts. To form a

rough estimate of the daily consumption of one of these immense flocks

let us first attempt to calculate the numbers of that above mentioned,

as seen in passing between Frankfort and the Indiana territory. If we

suppose this column to have been one mile in breadth (and I believe it

to have been much more), and that it moved at the rate of one mile in

a minute, four hours, the time it continued passing, would make its

whole length two hundred and forty miles. Again, supposing that each

square yard of this moving body comprehended three pigeons, the square

yards in the whole space, multiplied by three, would give two thousand

two hundred and thirty millions, two hundred and seventy-two thousand

pigeons!--an almost inconceivable multitude, and yet probably far below

the actual amount. Computing each of these to consume half a pint of

mast daily, the whole quantity at this rate would equal seventeen

millions, four hundred and twenty-four thousand bushels per day! Heaven

has wisely and graciously given to these birds rapidity of flight and

a disposition to range over vast uncultivated tracts of the earth,

otherwise they must have perished in the districts where they resided,

or devoured up the whole productions of agriculture, as well as those

of the forests.

A few observations on the mode of flight of these birds must not be

omitted. The appearance of large detached bodies of them in the air

and the various evolutions they display are strikingly picturesque and

interesting. In descending the Ohio by myself in the month of February

I often rested on my oars to contemplate their aërial manoeuvres. A

column, eight or ten miles in length, would appear from Kentucky,

high in air, steering across to Indiana. The leaders of this great

body would sometimes gradually vary their course until it formed a

large bend of more than a mile in diameter, those behind tracing the

exact route of their predecessors. This would continue sometimes long

after both extremities were beyond the reach of sight, so that the

whole, with its glittery undulations, marked a space on the face of

the heavens resembling the windings of a vast and majestic river.

When this bend became very great the birds, as if sensible of the

unnecessary circuitous course they were taking, suddenly changed their

direction, so that what was in column before, became an immense front,

straightening all its indentures, until it swept the heavens in one

vast and infinitely extended line. Other lesser bodies also united with

each other as they happened to approach with such ease and elegance

of evolution, forming new figures, and varying these as they united

or separated, that I never was tired of contemplating them. Sometimes

a hawk would make a sweep on a particular part of the column from

a great height, when, almost as quick as lightning, that part shot

downwards out of the common track, but soon rising again, continued

advancing at the same height as before. This inflection was continued

by those behind, who, on arriving at this point, dived down, almost

perpendicularly, to a great depth, and rising, followed the exact path

of those that went before. As these vast bodies passed over the river

near me, the surface of the water, which was before smooth as glass,

appeared marked with innumerable dimples, occasioned by the dropping of

their dung, resembling the commencement of a shower of large drops of

rain or hail.

Happening to go ashore one charming afternoon, to purchase some milk at

a house that stood near the river, and while talking with the people

within doors, I was suddenly struck with astonishment at a loud rushing

roar, succeeded by instant darkness, which, on the first moment, I

took for a tornado about to overwhelm the house and everything around

in destruction. The people, observing my surprise, coolly said: "It

is only the pigeons"; and on running out I beheld a flock, thirty or

forty yards in width, sweeping along very low between the house and the

mountain, or height, that formed the second bank of the river. These

continued passing for more than a quarter of an hour, and at length

varied their bearing so as to pass over the mountain, behind which they

disappeared before the rear came up.

In the Atlantic States, though they never appear in such unparalleled

multitudes, they are sometimes very numerous, and great havoc is

then made amongst them with the gun, the clap net, and various other

implements of destruction. As soon as it is ascertained in a town that

the pigeons are flying numerously in the neighborhood, the gunners

rise _en masse_, the clap nets are spread out on suitable situations,

commonly on an open height in an old buckwheat field; four or five

live pigeons, with their eyelids sewed up, are fastened on a movable

stick--a small hut of branches is fitted up for the fowler at the

distance of forty or fifty yards--by the pulling of a string the stick

on which the pigeons rest is alternately elevated and depressed, which

produces a fluttering of their wings similar to that of birds just

alighting; this being perceived by the passing flocks they descend with

great rapidity, and, finding corn, buckwheat, etc., strewed about,

begin to feed, and are instantly, by the pulling of a cord, covered by

the net. In this manner ten, twenty, and even thirty dozen have been

caught at one sweep. Meantime the air is darkened with large bodies

of them moving in various directions; the woods also swarm with them

in search of acorns; and the thundering of musketry is perpetual on

all sides from morning to night. Wagon loads of them are poured into

market, where they sell from fifty to twenty-five and even twelve cents

per dozen; and pigeons become the order of the day at dinner, breakfast

and supper, until the very name becomes sickening. When they have been

kept alive and fed for some time on corn and buckwheat their flesh

acquires great superiority; but, in their common state, they are dry

and blackish and far inferior to the full grown young ones or squabs.

The nest of the wild pigeon is formed of a few dry slender twigs,

carelessly put together, and with so little concavity that the young

one, when half grown, can easily be seen from below. The eggs are pure

white. Great numbers of hawks, and sometimes the bald eagle himself,

hover above those breeding places, and seize the old or the young

from the nest amidst the rising multitudes, and with the most daring

effrontery. The young, when beginning to fly, confine themselves to

the under part of the tall woods where there is no brush, and where

nuts and acorns are abundant, searching among the leaves for mast,

and appear like a prodigious torrent rolling through the woods, every

one striving to be in the front. Vast numbers of them are shot while

in this situation. A person told me that he once rode furiously into

one of these rolling multitudes and picked up thirteen pigeons which

had been trampled to death by his horse's feet. In a few minutes

they will beat the whole nuts from a tree with their wings, while

all is a scramble, both above and below, for the same. They have the

same cooing notes common to domestic pigeons, but much less of their

gesticulations. In some flocks you will find nothing but young ones,

which are easily distinguishable by their motley dress. In others they

will be mostly females, and again great multitudes of males with few

or no females. I cannot account for this in any other way than that,

during the time of incubation, the males are exclusively engaged in

procuring food, both for themselves and their mates, and the young,

being yet unable to undertake these extensive excursions, associate

together accordingly. But even in winter I know of several species

of birds who separate in this manner, particularly the red-winged

starling, among whom thousands of old males may be found with few or no

young or females along with them.

Stragglers from these immense armies settle in almost every part of

the country, particularly among the beech woods and in the pine and

hemlock woods of the eastern and northern parts of the continent. Mr.

Pennant informs us that they breed near Moose Fort, at Hudson's Bay, in

N. latitude 51 degrees, and I myself have seen the remains of a large

breeding place as far south as the country of the Choctaws, in latitude

32 degrees. In the former of these places they are said to remain until

December; from which circumstance it is evident that they are not

regular in their migrations like many other species, but rove about as

scarcity of food urges them. Every spring, however, as well as fall,

more or less of them are seen in the neighborhood of Philadelphia; but

it is only once in several years that they appear in such formidable

bodies; and this commonly when the snows are heavy to the north, the

winter here more than usually mild, and acorns, etc., abundant.

The passenger pigeon is sixteen inches long, and twenty-four inches in

extent; bill, black; nostril, covered by a high rounding protuberance;

eye, brilliant fiery orange; orbit, or space surrounding it, purplish

flesh-colored skin; head, upper part of the neck and chin, a fine

slate blue, lightest on the chin; throat, breast, and sides, as far as

the thighs, a reddish hazel; lower part of the neck and sides of the

same, resplendent changeable gold, green, and purplish crimson, the

last named most predominant; the ground color, slate; the plumage of

this part is of a peculiar structure, ragged at the ends; belly and

vent, white; lower part of the breast, fading into a pale vinaceous

red; thighs, the same; legs and feet, lake, seamed with white; back,

rump, and tail-coverts, dark slate, spotted on the shoulders with

a few scattered marks of black; the scapulars, tinged with brown;

greater coverts, light slate; primaries and secondaries, dull black,

the former tipped and edged with brownish white; tail, long, and

greatly cuneiform, all the feathers tapering towards the point, the

two middle ones plain deep black, the other five, on each side, hoary

white, lightest near the tips, deepening into bluish near the bases,

where each is crossed on the inner vane with a broad spot of black,

and nearer the root with another of ferruginous; primaries edged with

white; bastard wing, black.

The female is about half an inch shorter, and an inch less in extent;

breast, cinerous brown; upper part of the neck, inclining to ash; the

spot of changeable gold, green, and carmine, much less, and not so

brilliant; tail coverts, brownish slate; naked orbits, slate colored;

in all other respects like the male in color, but less vivid and more

tinged with brown; the eye not so brilliant an orange. In both the tail

has only twelve feathers.
