Skua (Lestris catarractes, Temminck), s. A species of eagle.

This species is rather superior in size to the raven; weight three pounds; length two feet; the bill is an inch and three quarters long, black, and much hooked at the end; is covered, for more than half its length, with a kind of black cere; the upper part of the head, neck, back, and wings, deep brown; the feathers margined with ferruginous; about the forehead and chin tinged with ash-colour; the breast, and all beneath, pale dusky ferruginous; the quills are brown, white at the base; tail deep brown; roots and shafts white; the legs are black, rough, and scaly; talons black, strong, and much hooked.

This is a bold rapacious bird, and preys on the lesser gulls, as well as fish; it is said to attack the eagle, and even man, if he approaches their nest. It breeds in the Orkney Islands, and is much esteemed in the Isle of Foulah, from a supposition that it defends the flocks from the eagle: it is rarely seen in the south. One in the museum of Dr. Latham, was killed at Greenwich; and the only other instance we are furnished with, of this species being observed in the south of England, was shot at Sandwich, in Kent, in the winter of 1800.—Montagu.
