Common raven

The common raven (Corvus corax) is among the largest passerines, 54–71 cm long with a 116–153 cm wingspan and a weight of 0.69–2.25 kg. It is wholly black with metallic gloss, shaggy throat hackles and a wedge-shaped tail. Its Holarctic range covers about 137 million square kilometres, from Arctic tundra and conifer forest to desert and plateau above 5,000 m. Omnivorous and opportunistic, it takes carrion, insects, small vertebrates, grain and human refuse and caches food. It lays 2–7 eggs from January. The IUCN lists it Least Concern.
