n.
Any of several species (genus Corvus , crow family Corvidae) of heavy-billed, usually solitary, songbirds, once abundant throughout the Northern Hemisphere but now restricted to undisturbed areas.
The common raven ( C. corax ), the biggest passerine , grows to 26 in. (66 cm) long and has a wingspan of more than 4 ft (1.3 m). The dark, iridescent plumage is shaggy, especially around the throat. Ravens eat rodents, insects, grain, birds' eggs, and, in winter, carrion and refuse. Captive nestlings may learn to mimic a few words. The large nest, a crude structure of sticks, is built high on a cliff or treetop.
