BIRDS CONSPICUOUSLY BLACK

COMMON CROW

(Corvus americanus) Crow family Called also: CORN THIEF; [AMERICAN CROW, AOU 1998]

Length -- 16 to 17.50 inches.

Male -- Glossy black with violet reflections. Wings appear saw-toothed when spread, and almost equal the tail in length.

Female -- Like male, except that the black is less brilliant.

Range -- Throughout North America, from Hudson Bay to the Gulf of Mexico.

Migrations -- March. October. Summer and winter resident.

If we have an eye for the picturesque, we place a certain value upon the broad, strong dash of color in the landscape, given by a flock of crows flapping their course above a corn-field, against an October sky; but the practical eye of the farmer looks only for his gun in such a case. To him the crow is an unmitigated nuisance, all the more maddening because it is clever enough to circumvent every means devised for its ruin. Nothing escapes its rapacity; fear is unknown to it. It migrates in broad daylight, chooses the most conspicuous perches, and yet its assurance is amply justified in its steadily increasing numbers.

In the very early spring, note well the friendly way in which the crow follows the plow, ingratiating itself by eating the larvae, field mice, and worms upturned in the furrows, for this is its one serviceable act throughout the year. When the first brood of chickens is hatched, its serious depredations begin. Not only the farmer's young fledglings, ducks, turkeys, and chicks, are snatched up and devoured, but the nests of song birds are made desolate, eggs being crushed and eaten on the spot, when there are no birds to carry off to the rickety, coarse nest in the high tree top in the woods. The fish crow, however, is the much greater enemy of the birds. Like the common crows, this, their smaller cousin, likes to congregate in winter along the seacoast to feed upon shell-fish and other sea-food that the tide brings to its feet.

Samuels claims to have seen a pair of crows visit an orchard and destroy the young in two robins' nests in half an hour. He calculates that two crows kill, in one day alone, young birds that in the course of the season would have eaten a hundred thousand insects. When, in addition to these atrocities, we remember the crow's depredations in the corn-field, it is small wonder that among the first laws enacted in New York State was one offering a reward for its head. But the more scientific agriculturists now concede that the crow is the farmer's true friend.

FISH CROW (Corvus ossifragus) Crow family Length -- 14 to 16 inches. About half as large again as the robin.

Male and Female -- Glossy black, with purplish-blue reflections, generally greener underneath. Chin naked.

Range -- Along Atlantic coast and that of the Gult of Mexico, northward to southern New England. Rare stragglers or) the Pacific coast.

Migrations -- March or April. September. Summer resident only at northern limit of range. Is found in Hudson River valley about half-way to Albany.

Compared with the common crow, with which it is often confounded, the fish crow is of much smaller, more slender build. Thus its flight is less labored and more like a gull's, whose habit of catching fish that may be swimming near the surface of the water it sometimes adopts. Both Audubon and Wilson, who first made this species known, record its habit of snatching food as it flies over the southern waters -- a rare practice at the north. Its plumage, too, differs slightly from the common crow's in being a richer black everywhere, and particularly underneath, where the "corn thief" is dull. But it is the difference between the two crows' call-note that we chiefly depend upon to distinguish these confusing cousins. To say that the fish crow says car-r-r instead of a loud, clear caw, means little until we have had an opportunity to compare its hoarse, cracked voice with the other bird's familiar call.
