Part 17

Male and female birds share the duties of incubating the eggs, which are turned over carefully so that they get the proper amount of heat. Sometimes the eggs are so numerous that they are piled upon each other in the nest, and at such times the lower layer of eggs must receive special attention. As a rule, all the eggs hatch.

Among the enemies of Bob-Whites are the blacksnake, which eats the eggs and young; the Cooper’s Hawk and the Goshawk, which capture the adults; and the skunk and other ground-prowlers which eat the eggs and sometimes the adults. Half-starved house cats are frequently serious enemies of this popular game-bird.

The Hungarian or European Gray Partridge (Perdix perdix perdix), a bird a little larger than the Bob-White, gray in color with a dark brown horse-shoe shaped mark on the breast, a red-brown tail, and reddish eyelids, has been released in several parts of Pennsylvania as a game-bird, and it is now on the increase. The bright red-brown tail of this species is very noticeable in flight.

RUFFED GROUSE Bonasa umbellus umbellus (Linnæus)

Other Names.—Partridge; Gray Partridge; Birch Partridge; Silver-tail (gray phase); Pheasant (erroneous).

Description.—Size of chicken, with broad, fan-shaped tail; sexes similar. Upperparts principally reddish brown, irregularly marked with black, buffy, gray, and whitish; sides of neck with ruffs of broad, black feathers glossed with greenish; tail reddish brown or gray, or of intermediate shade, irregularly barred and mottled with black, with a broad blackish band near end, and a gray tip; throat and breast buffy; rest of underparts white, tinged with buffy and barred with black or dark brown, the bars indistinct on the breast and belly, stronger on the sides. The female, which is a little smaller, has smaller ruffs on the neck, and, as a rule, a shorter tall. Length: 17 inches.

Range in Pennsylvania.—A permanent resident throughout in the wilder, wooded sections; variable in abundance as a result of unfavorable nesting seasons, change of forest conditions, destruction by natural enemies, disease, and heavy hunting.

Nest.—A hollow lined with leaves at the base of a stump, under a low hemlock, or under the fallen branch of a tree. Eggs: 7 to 14, pale buffy.

The Ruffed Grouse, our best-known game-bird, is a creature of personality. Protectively colored, he waits until he is almost trodden upon, then rises with a startling whir of wings, leaving the wayfarer thunderstruck. The female, as she incubates, is rarely seen, for she does not stir, and her back perfectly imitates her surroundings.

In the spring, the male Grouse struts and drums at chosen spots in the woodland. On a log he paces up and down, ruffs lifted, wide tail fully spread and elevated; or he stands erect, and, beating his chest rapidly with his wings, produces the drumming sound for which he is so famous. Grouse may drum at any time of the year, and sometimes at night, but they do so chiefly during the morning on spring days.

The young run nimbly soon after hatching and leave their nest at once. They develop rapidly. After a week they can fly readily though they are very small. The mother Grouse, in luring an enemy from her young, employs broken-wing tactics, dragging herself over the ground as though she were badly wounded.

In the winter, Grouse develop long lateral scales on their toes which function as snow-shoes. Their neat tracks in the snow lead from a roost under a branch to which dead leaves cling, and wander about the bushes and trees where the birds have been feeding on buds, twigs, and dried berries. Grouse are especially fond of aspen, birch, beech, and maple buds. They like wild-grape vines both for the food and the shelter which they afford. During summer, Grouse eat much insect food, as well as berries and leaves. They sometimes eat hemlock needles and leaves of mountain laurel.

WILD TURKEY Meleagris gallopavo silvestris Vieillot

Description.—Size and appearance very similar to that of the domestic bird, but tips of tail-feathers and upper tail-coverts rich deep chestnut; primaries barred with black and white; feet mahogany-red. A large Wild Turkey gobbler in spring is a magnificent creature with its rich, iridescent plumage, highly colored and wattled head, and proud carriage. Length: About 4 feet.

Range in Pennsylvania.—Once fairly common throughout the State, especially in the southern mountainous counties, but brought to the verge of extermination through forest fires, excessive hunting, and encroaches of civilization. The Game Commission has brought in some birds from other States to replenish our stock; some mingling has occurred between wild birds and domestic individuals which have wandered from the farms. Wild Turkeys are now to be found chiefly along the ridges of the South Mountain District, and seem to be holding their own fairly well. While these are not strictly the original strain, they are nevertheless wild, and are therefore fairly representative of the race which once occurred. The Wild Turkey is a permanent resident.

Nest.—A depression in the leaves, under brush, or in a thicket, usually well concealed from above. Eggs: 6 to 15, cream-buff, thickly but finely spotted with reddish brown.

The sight of a flock of Wild Turkeys coasting on their strong wings from the crest of a ridge to the lower levels is one long to be remembered. The spectacle before us, of weighty, muscular creatures hurling themselves through the air is difficult to believe, accustomed as we are to the flightless clumsiness of their cousins of the barnyard.

Having very keen senses, the Wild Turkeys are difficult to approach, for they are very wary and at the slightest warning make off on a run up the ridge, or leap into the air.

In summer, they eat many small fruits and insects, including grasshoppers, but in winter, when it is often necessary for them to scratch in the snow, they eat chestnuts and acorns, the berries of Jack-in-the-pulpit, corn if they live near the farms, and other such food as they can find. In some districts these splendid birds have difficulty in finding adequate food to carry them through the winter and in such regions the Game Protector sees that the birds are fed, and Boy Scouts, sportsmen’s organizations, and others coöperate in saving the birds.

The Wild Turkey gobbler, notably in the spring, has the same tendencies toward fighting and vainglorious display as has his domestic relative.

MOURNING DOVE Zenaidura macroura carolinensis (Linnæus)

Other Names.—Carolina Dove; Rain Crow (erroneous); Turtle Dove.

Description.—A little larger than a Robin; head small, tail long and pointed. Adults: Crown clear gray; front of head, face, throat, and lower neck, soft reddish brown, two small black spots back of and below the eye; sides and back of neck gray, with patches of iridescent feathers which reflect greenish, golden, and purplish lights; back and wings grayish brown, some of the coverts and tertials with black spots; rump and tail gray, the outer tail-feathers noticeably tipped with white; underparts pinkish brown, lightest on belly and under tail-coverts; bill black; feet reddish. Female: Less brightly colored than male. Young birds in their first flight plumage are much scaled in appearance and lack the bright colors of the adult. Length: About 12 inches.

Range in Pennsylvania.—A common summer resident throughout, arriving in late March and remaining until November. It is occasionally found in winter when the ground is free of snow or when food in the form of seed or grain is plentiful. In many sections it is becoming commoner.

Nest.—A flimsy, flat structure made of small twigs, weed-stalks, or other bits of vegetation, placed, usually, on a horizontal branch or in an ample crotch in an orchard tree or willow, often near a stream, and usually not at great height from the ground. The nest is sometimes placed on the ground. Eggs: 2, white.

Doves are often to be seen perched on a prominent dead branch, and at such times their small heads, erect posture, and pointed tails are noticeable. As they fly up from a field, or alight, the white in their outer tail-feathers shows plainly, but wherever they occur they may be recognized by the characteristic whistling sound of their wings in flight and their gentle cooing. This song may be written coo-oo-oo, ooh, ooh, ooh, the opening syllable using three notes, the middle note being the highest in the song. At close range this cry is rough and throaty; at a distance it is mellow and soft, its tender, mournful quality making adequate description difficult.

Young Doves are fed with partly digested food which the parents pump up from their stomachs. They are helpless, dowdy creatures while in the nest, and they sometimes come to an untimely end when a gale blows the structure from its scant moorings or when, from lack of proper balance, it topples to one side.

The white eggs, when fresh, are translucent as moonstones, and the sunlight, in penetrating the thin shells, discloses faintly the color of the golden yolk.
