DISTRIBUTION

Iran to India, Pakistan and Burma, self-introduced to East Africa, Indian Ocean islands, Malaysia, and South Africa.

HABITAT

Wholly dependent on human habitation; consequently found in villages, towns, and cities throughout its range.

BEHAVIOR

Highly vocal, gregarious birds, seemingly unafraid of humans. Will attack and chase off any large bird of prey.

FEEDING ECOLOGY AND DIET

Omnivorous. Diet includes seeds, fruit, grain, nectar, berries, bird's eggs, nestlings, mammals, reptiles, amphibians, fish, insects, wide range of carrion.

REPRODUCTIVE BIOLOGY

Solitary nester except in areas of high population density. Will use trees, buildings, or other artificial structures for rough stick nest. Three to four eggs March through July. Incubation 16–17 days; fledging 21–28 days.

CONSERVATION STATUS

Not threatened. Abundant throughout range.

SIGNIFICANCE TO HUMANS

Regarded as a major agricultural and human health pest in self-introduced areas. In South Africa, birds have been reported taking food from school children, killing chicks of domestic fowls, and repeatedly dive-bombing any person near the nest.

The House Crow (Corvus splendens), also known as the Colombo Crow is a common Asian bird of the Crow family. It is between the Jackdaw and the Carrion Crow in size (40 cm in length) but is relatively slimmer than either. The forehead, crown, throat and upper breast are a richly glossed black, whilst the neck and breast are a lighter grey-brown in colour. The wings, tail and legs are black. There are regional variations in the thickness of the bill and the depth of colour in areas of the plumage.

It has a widespread distribution in southern Asia, being native to India, Pakistan, Sri Lanka, Maldives and Laccadive Islands, South West Thailand and coastal southern Iran. It has been introduced to East Africa around Zanzibar and Port Sudan, and arrived in Australia via ship but has up to now been exterminated. It is associated with human settlements in all of its range, from small villages to large cities.

Due to a human population explosion in the areas it inhabits, this species has also proportionately multiplied. Being an omnivorous scavenger has enabled it to thrive in such circumstances. Moreover this species (like several other Corvus species) is known for its cleverness. Among bird hunters it is generally accepted that unlike most birds, these crows can instantly recognise a gun and take flight in an instant.

Behaviour

Diet

It feeds largely on human scraps, small reptiles and other animals such as insects and other small invertebrates, eggs, nestlings, grain and fruits. Most food is taken from the ground, but also from trees as opportunity arises. It is a highly opportunistic bird and given its omnivorous diet, it can survive on nearly anything that is edible.

Nesting

At least some trees in the local environment seem to be necessary for its successful breeding. It lays 3-6 eggs in a typical stick nest, and occasionally there are several nests in the same tree. In South Asia they are parasitized by the Asian Koel.
