COLUMBA LIVIA ____ ROCK PIGEON

(_about one half Nat. size_)]

"The Pinnated Grouse," says Audubon, "moves through the air with frequent

beats, after which it sails with the wings bent downwards, balancing

itself for a hundred yards or more, as if to watch the movements of its

pursuer, for at this time they can be easily observed to look behind them

as they proceed. They never rise when disturbed without uttering four or

five distinct clucks, although at other times they fly off in silence.

The ordinary voice of this species nearly resembles that of our domestic

fowls, but during the pairing season the male utters a peculiar call.

"The curious notes," continues the same writer, "emitted in the love

season are peculiar to the male. When the receptacles of air above

alluded to, which in form, colour, and size resemble a small orange, are

perfectly inflated, the bird lowers its head to the ground, opens its

bill, and sends forth, as it were, the air contained in these bladders in

distinctly-separated notes, rolling one after another, from loud to low,

and producing a sound like that of a large, muffled drum. This done, the

bird immediately erects itself, refills its receptacles by inhalation,

and again proceeds with its 'tootings.'" Audubon observed in those

Prairie Hens he tamed, that after producing the noise the bags lost their

rotundity and assumed the appearance of a burst bladder, but in a few

seconds became again inflated. He caught one of these birds and pierced

the air-cells with the point of a pin, after which it was unable to "toot"

any more. Another bird, of which he punctured one cell only, was unable to

inflate that one, but next morning could toot with the other, though not

so loudly as before. As soon as the pairing and fighting season is over,

the bladders collapse and are concealed beneath the feathers of the ruff.

During the winter they are much reduced in size. The bladders and long

neck-feathers are seen on the young males before the first winter, and

in the spring attain maturity, but they increase in size and beauty for

several years.

These birds live both on vegetable food and on insects. During the sowing

season they visit corn-fields of various kinds, where they do considerable

damage. They feed on the barberry, and various other berries growing on

low shrubs, on buds of various plants, and on acorns. "In the western

country," says Audubon, "these birds frequent the sumach bushes to feed

on their seeds, often in such numbers that I have seen them bent by their

weight, and I have counted more than fifty on a single apple-tree, the

buds of which they entirely destroyed in a few hours. They also alight

on high forest trees on the margins of large rivers. During winter these

Grouse congregate in large flocks, but as soon as the snows have melted

away, and the first blades of grass issue from the earth, announcing

the approach of spring, they separate into parties of fifty or more,

their love season commences, and a spot is pitched upon to which they

daily resort until incubation is established. Inspired by love, the male

birds, before the first glimpse of day lightens the horizon, fly swiftly

and singly from their grassy beds to meet, to challenge, and to fight

the various rivals led by the same impulse to the arena. The male is at

this season arrayed in his full dress, and enacts his part in a manner

not surpassed in pomposity by any other bird. Imagine them assembled to

the number of twenty by daybreak; see them all strutting in presence of

each other; mark their consequential gestures, their looks of disdain,

and their angry pride as they pass each other. Their tails are spread out

and inclined forwards to meet the expanded feathers of their neck, which

now, like stuffed frills, lie supported by the globular, orange-coloured

receptacles of air from which their singular booming sounds proceed. Their

wings, like those of the Turkey Cock, are stiffened, and declined so as

to rub and rustle on the ground as the bird passes rapidly along. Their

bodies are depressed towards the ground, the fire of their eyes evinces

the pugnacious workings of their minds, their notes fill the air around,

and at the very first answer from some coy female the heated blood of the

feathered warriors swells every vein, and presently the battle rages. Like

Game Cocks, they strike and rise in the air to meet their assailants with

greater advantage. Now many close in the encounter; feathers are seen

whirling in the agitated air, or falling around them tinged with blood.

The weaker begin to give way, and one after another seek refuge in the

neighbouring bushes. The remaining few, greatly exhausted, maintain their

ground, and withdraw slowly and proudly, as if each claimed the honours

of victory. The vanquished and the victors then search for the females,

who, believing each to have returned from the field in triumph, receive

them with joy. It not unfrequently happens that a male already mated is

suddenly attacked by some disappointed rival, who unexpectedly pounces

upon him after a flight of considerable length, having been attracted by

the cackling of the happy couple. The female invariably squats next to and

almost under the breast of her lord, while he, always ready for action,

throws himself on his daring antagonist, and chases him away never to

return."

In tracts of land in the western country, the Pinnated Grouse may be heard

booming and tooting before break of day, and at all hours afterwards until

sunset; but in those districts where they have been frequently annoyed

by that intruder, man, their meetings are more noiseless, their battles

shorter and less frequent, and their fighting-grounds more concealed. Many

of the young males fight in the autumn, the females generally joining them

to make peace.

The nest is made earlier or later, according to the latitude of the place,

between the beginning of April and the end of May. Audubon found a nest in

Kentucky finished and containing a few eggs at the first-mentioned date;

but he thinks, taking the difference of seasons into consideration, that

the average time is about the beginning of May. The nest, which is formed

of dry leaves and grass, neatly interwoven, is carefully placed amid the

tall grass, or a large tuft in the open ground, or at the foot of a bush.

The eggs are from eight to twelve in number, and are of a light colour.

The mother sits upon the nest eighteen or nineteen days, and as soon as

the young have freed themselves, leads them away from the nest, when the

male ceases to associate with her. In autumn the families congregate

together in flocks, which at the approach of winter consist of several

hundreds. When alarmed, the young squat so closely in the grass as to be

quite hidden. "Once," says Audubon, "my horse almost placed his foot on a

covey that was in the path. I observed them, and instantly leaped to the

ground; but, notwithstanding all my endeavours, the cunning mother saved

them by a single cluck. The little fellows rose on the wing for only a few

yards. I spent much time in search of them; I could not discover one. I

was greatly amused, however, by the arts the mother employed to induce me

to leave the spot where they lay concealed."

These birds never have more than one brood during the year; but should the

eggs have been destroyed, a second set is laid, generally fewer in number

than the first. About the 1st of August the young are nearly as large as

the little American Partridge, and are then fit for the table; but they do

not become strong in the wing till the middle of October.

The war against these Grouse is carried on in various ways. Some are shot

on their breeding-places, others killed with sticks, or caught in nets and

snares. "I observed," says Audubon, "that for several nights in succession

many of these Grouse slept in a meadow not far distant from my house. This

piece of ground was thickly covered with tall grass, and one dark night I

thought of amusing myself by trying to catch them. I had a large seine,

and took with me several negroes supplied with lanterns and long poles,

with the latter of which they bore the net completely off the ground. We

entered the meadow in the early part of the night, although it was so dark

that without a light, one could hardly have seen an object a yard distant,

and spreading out the leaded end of the net, carried the other end forward

by means of the poles, at the height of a few feet. I had marked before

dark a place in which a great number of the birds had alighted, and now

ordered my men to proceed towards it. As the net passed over the first

Grouse in the way, the alarmed bird flew directly towards the confining

part of the angle, and almost at the same moment a great number of others

arose, and, with much noise, followed the same direction. At a signal, the

poles were laid flat on the ground, and we secured the prisoners, bagging

some dozens. Repeating our experiment three times in succession, we met

with equal success; but now we gave up the sport on account of the loud

bursts of laughter from the negroes, who could no longer refrain. Leaving

the net on the ground, we returned to the house laden with spoil, although

I am confident that several hundreds had escaped."

"The Pinnated Grouse," as Audubon further relates, "is easily tamed, and

easily kept. It also breeds in confinement. I have often been surprised,"

he continues, "that it has not been fairly domesticated. While at

Henderson I purchased sixty alive that were expressly caught for me within

twelve miles of that village, and brought in a bag laid across the back

of a horse. I cut the tips of their wings, and turned them loose in a

garden and orchard about four acres in extent. Within a week they became

tame enough to allow me to approach them without their being frightened. I

supplied them with abundance of corn, and they fed besides on vegetables

of various kinds. This was in the month of September, and almost all of

them were young birds. In the course of the winter they became so gentle

as to feed from the hand of my wife, and walked about the garden like

so many tame fowls, mingling occasionally with the domestic poultry. I

observed that at night each individual made choice of one of the heaps in

which a cabbage had grown, and that they invariably turned their breast

to the wind, whatever way it happened to blow. When spring returned

they strutted, 'tooted,' and fought, as if in the wilds where they had

received their birth. Many laid eggs, and a good number of young ones made

their appearance; but the Grouse at last proved so destructive to the

young vegetables--tearing them up by the roots--that I ordered them to

be killed. So brave were some of the male birds that they never flinched

in the presence of a Turkey Cock; and now and then would stand against a

Dunghill Cock for a pass or two before they would run from him."

The PTARMIGANS (_Lagopus_) constitute a group of remarkable birds,

characterised by their very compact body, medium-sized wings, in which the

third quill is the longest, a short, slightly rounded, or straight tail,

composed of eighteen feathers, and a small beak. The comparatively small

feet have the tarsi and toes covered with hairy feathers. The rich plumage

varies in its hues according to the season of the year; the sexes are very

similar in their coloration, and the young soon acquire the same tints

as their parents. The unusually large claws possessed by the members of

this group are shed, like those of their congeners, when the plumage is

changed. The Ptarmigans inhabit both America and the Eastern Hemisphere as

far northward as vegetation extends, and have occasionally been seen even

at 80° north latitude. In a southerly direction they are met with as far

as the Alps, the Pyrenees, and the mountains of Central Europe.

These birds live on open ground, and feed upon twigs and leaves of shrubs,

berries, grasses, and seeds; their flight is quick, strong, and prolonged.

They walk and run very nimbly, and often escape from their pursuers by

hiding under shrubs or among heather, when much alarmed they take wing,

but even then never resort to the woods for shelter. Their eggs, which are

numerous, are spotted with dark brown. The young run about as soon as they

leave the egg, and follow their mother in search of food. At the approach

of winter several families frequently associate together.
