[The young undergo no change of feather until their second autumn ; and they renew their plumage slowly, and in no instance more than once in the year ; its seasonal change being confined to a slight wearing off, rather than a natural shedding, of the margins of the feathers : in several species, however, the colour indicative of maturity is partially ac- quired, previously to moulting, by a change of hue in the first or nestling plumage. The eggs of Accipitrine Birds are nearly spherical ; and those of the present division are gene- rally more or less spotted or blotched with rusty-brown. The young are at first densely clad in short soft down.] Linnaeus made only two genera, which are two natural divisions,—the Vultures and the Falcons. —AIimem«ryCanal of the Coi exhibiting the first mon Buzzard : raw; and (be- ) the prove low the divaiicHtion ot the track triculus, stomach, and intestint figure represents the termination of intestines, with tlie rectum form the cloaca, and two ttie junction of the eat and small intestines.

The force of their talons does not correspond with their stature, and they make more use of their beak than of their claws. Their wings are so long, that in walking they hold them half-extended. They are of a cowardly disposition, and feed on carrion oftener than on living prey : when they have gorged themselves, their craw forms a large protube
