Physical charateristics

Quite large attenuated crow, lacking bulk of common large European black crows and having distinctive bill and head profile.

Range

Oriental Region : Northwest India through Southwest Thailand

Habitat

Original range lies in Indian subcontinent, in subtropical and tropical lowlands, also in hills up to somewhat more than 2000 m, but does not ascend from Indus valley to highland Baluchistan within that limit, and has established only precarious foothold in Vale of Kashmir.
Presence of some trees probably essential, roosts communally in mangroves, banyans, coconuts, and in tree plantations, often reached by long high-level flights.
Has become intricately enmeshed with human activities in urban and even metropolitan areas.

Reproduction

Breeds from may to start of august. Nest site, always close to human habitation, in fork near top of tall tree or in outermost branches, often in banyan or mango. in Israel in groves of tamarisk. The nest is a untidy mass of twigs, often thorny, sticks plastic, string, assorted pieces of metal, electrical cable, etc. Depression in center lined with fibres of wood or bark, grass, hair, cloth, and similar soft material, though can be unlined. Clutch size 3-5 eggs, very variable in shape, size, and color. Incubation lasts 15-17 days, by both sexes.

Feeding habits

Very dependent on man’s rubbish, scraps, offal, and sewage, otherwise any edible invertebrates, small vertebrates, plant material, or carrion. Feeds mostly on ground, but also in trees and on buildings. Forages mainly at rubbish tips, abattoirs, markets, farms, beaches near fisheries or tourist resorts, etc., travelling up to 15 km from rosst to feeding place.

Conservation

This species has an extremely large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). The population trend appears to be stable, and hence the species does not approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size has not been quantified, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.
House Crow status Least Concern
