For foraging, they use wide-open, short-grass areas that are easy to survey, so both elements must occur in some proximity to each other. Regionally, rock cliffs may also serve this function. The birds depend on trees, tall shrubs, or comparable anthropogenic structures as roosting, nesting, and perching sites. Open and semi-open landscapes characterize the preferred habitats of carrion crows. In addition, the colours of the plumage are tinted brownish, and in young hooded crows the black breast patch is also less pronounced than in adults.
The legs and the beak are slate-coloured in both morphs, and the iris of adult birds is dark brown. Juvenile carrion crows are distinguished from adults by their less voluminous plumage and somewhat slimmer silhouette. Birds from the Mediterranean region show distinct black feather shafts in the white plumage areas. The thighs of hooded crows are feathered black, but are often covered by a grayish veil.
The nape, back, and shoulder coverts, on the other hand, are ash-gray to white, as are the small uppertail coverts, lateral breast, belly, and lower tail coverts. The black and gray morph, called the hooded crow, matches the carrion crow in colouration of the head, central breast, tail, and wings. With increasing time, the plumage loses saturation and luster and turns slightly brownish, especially on the wing feathers. The bases of the breast and belly feathers are light gray. corone corone) is characterized in fresh plumage by a dull, metallic sheen that ranges between green and blue and is less pronounced than in rooks (C. Mixed forms of different characteristics may also occur. The species occurs in a completely black and a black and gray plumage morph.
The wing tips extend just beyond the tip of the tail when appressed. Their wings are relatively long and moderately digitted, and their tails are broad and slightly rounded. Their elevated, slightly curved and robust beak, their short, close-fitting thigh feathers and voluminous body plumage give them a compact, stocky appearance. Carrion crows achieve a body length of 45 to 47 cm and a wingspan of 93 to 104 cm when fully grown.
