The hooded crow (Corvus cornix) (also called hoodie) is a Eurasian bird species in the Corvus genus. Widely distributed, it is also known locally as Scotch crow, Danish crow, and grey crow (in Slavic languages, Ireland and Denmark). Found across Northern, Eastern, and Southeastern Europe, as well as parts of the Middle East, it is an ashy grey bird with black head, throat, wings, tail, and thigh feathers, as well as a black bill, eyes, and feet. Like other corvids, it is an omnivorous and opportunistic forager and feeder.
It is so similar in morphology and habits to the carrion crow (Corvus corone), for many years they were considered by most authorities to be geographical races of one species. Hybridization observed where their ranges overlapped added weight to this view. However, since 2002, the hooded crow has been elevated to full species status after closer observation; the hybridisation was less than expected and hybrids had decreased vigour. Within the hooded crow species, four subspecies are recognized, with one, the Mesopotamian crow, possibly distinct enough to warrant species status itself.
Except for the head, throat, wings, tail, and thigh feathers, which are black and mostly glossy, the plumage is ash-grey, the dark shafts giving it a streaky appearance. The bill and legs are black; the iris dark brown. Only one moult occurs, in autumn, as in other crow species. The male is the larger bird, otherwise the sexes are alike. Their flight is slow and heavy and usually straight. Their length varies from 48 to 52 cm (19 to 20 in). When first hatched, the young are much blacker than the parents. Juveniles have duller plumage with bluish or greyish eyes and initially a red mouth. Wingspan is 98 cm (39 in) and weight is on average 510 g.
The hooded crow, with its contrasted greys and blacks, cannot be confused with either the carrion crow or rook, but the About this sound kraa (help·info) call notes of the two are almost indistinguishable.
