Black hooded crow

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. There is only one moult, in autumn, as in other crow species. The male is the larger bird, otherwise the sexes are alike. The flight is slow and heavy and usually straight. The 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 grammes.
