Collier's New Encyclopedia (1921)
the English name of the buteo, a genus of birds, and especially of three species. These are: 1. The turkey buzzard (cathartes aura). This genus is more a carrion vulture than a raptorial bird, like some N BUZZARD of the other genera described below. They are natives of our Southern States, where they are very useful as scavengers, and are so much appreciated in this regard that in most of the States they are protected by law. In consequence they grow quite tame, and in some places may be considered almost a domesticated fowl. They are about the size of a common turkey, and the species 1 gets its name from a distant resemblance between the two. They are of a dirty black color, and are from 25 to 36 inches long, having an immense span of wing (proportionate), being remarkable for propor their powerful and graceful flight. Its nest is a mere re hollow in the ground with a rampart of loose, dead ead branches around it. These birds may be seen by hundreds in one locality, hovering over and lighting upon the carcass of a dead animal. They are rarely found N. of Pennsylvania. 2. The brown buzzard (buteo vulgaris), called also the glead, glede, glade, kite or puttock. The male is deep brown above, the margins of the feathers paler, the under parts yellowish white with brown spots, the face with brown and pale bands. The female is deep brown above and below, with whitish streaks on the throat, and spots of the same color on the breast. It feeds on small mammalia, birds, lizards, . It makes it worms and insects. insects It makes its nest in trees and ledges of rock. 3. The rough legged buzzard (buteo lagopus), which is feathered to the toes.
Aiton's Encyclopedia (1910)
or Turkey Vulture, a bird of prey belonging to the family of American vultures. The common species ranges from Manitoba to Patagonia. In the northern part of the Mississippi Valley, the buzzard seems to be sharing the fate of other large birds. It becomes rarer from year to year, but in the south it is protected by law, and is the official scavenger of farm and town, taking care of a dead farm animal, a cat in the gutter, or of kitchen offal. It shambles out of the way of a foot passenger, but is almost as fearless as a turkey. It has a hooked yellow bill, a bare, bright red head and neck, black glossy plumage edged with brown, and a meager body about thirty inches in length. The nest, with three dirty white, chocolate-speckled eggs, is placed in a hollow stump, or on the ground like that of a turkey. A smaller species, the black vulture, performs a similar service in South America . The buzzard is a serviceable, but necessarily a revolting bird. In its flight only, the buzzard is admirable. Whether coursing with soft wing and keen eye in search of food, or soaring aloft in graceful spirals, the buzzard's flight is the poetry of motion. Buzzards see a long distance. Should a buzzard discover a carcass, his dropping would be noted by some distant neighbor, who would hurry to the scene, noticed in turn by others, and these by others still further off, until, in an incredibly short time, a large assemblage had gathered. Travelers on the plains state that saddle and bridle cannot be removed from a spent horse before a circle of impatient buzzards has formed, even though not one was in sight a moment before.
