The House Crow is a slim, small to medium-sized crow with a flat crown, comparatively long legs and neck particularly when alert, and a substantial bill. The sexes are alike, though males are slightly larger on average. The adults are glossy black with a grey neck, upper back and lower breast, often with a brownish tinge. This hood varies in darkness between the races, with the palest race being centred in Pakistan and the darkest in Myanmar. The bill and legs are black and the eyes dark brown. The tail is black, fairly long and has a rounded end. Juveniles are generally duller.
Identification is made easier by the fact that House Crows are never found far from human habitation, although they may forage in the nearby farmland and often follow livestock into pastureland, or search for food along river banks and seashores. They move around on the ground with a bold striding gait and have little fear of man, but remain cautious at all times and are easily alarmed. Commonly encountered in pairs or small groups, they are usually highly vocal, typically emitting a rather flat and nasal sounding “kaaa-kaaa” which increases in intensity and frequency between contact and alarm calls. They also gather in larger noisy groups at traditional roosts, food sources and when mobbing perceived threats.
