The House crow (Corvus splendens) is a common bird of the crow family that is of Asian origin but now found in many parts of the world, where they arrived assisted by shipping.
The House crow is relatively small and slim-bodied, with long legs and plumage that is mostly black or blackish-slate. ‘Shining raven’ is the meaning of its scientific name, referring to its glossy, jet-black feathers around the face, chin, crown, and throat. Males and females are similar in appearance. Juveniles have duller plumage which does not feature the adults’ glossy black sheen.

House crows are omnivorous, eating rubbish, leftovers, debris, and sewage. They also eat lizards, fish, frogs, crabs, insects, nectar, fruits, the seeds of cereal, eggs, chicks, and small mammals.
The House crow is widely distributed throughout southern Asia, from southern Iran through Pakistan, India, and Bangladesh and into south-western China, southern Tibet, and central Thailand, as well as the Maldives. It has been introduced to places in Africa, Europe, the Middle East, and several islands, such as Mauritius. A small population is established around St. Petersburg, Florida. It is typically a lowland species, found in both tropical and subtropical areas. Some, however, have been seen in Himalayan military bases. This bird is strongly associated with humans, living in cities, towns, and villages. Interestingly, no populations are known to live in areas where there are no people.
A House crow is very intelligent and is always wary and alert, walking or hopping along while flicking its wings nervously. It is a diurnal, non-migratory, social species and gathers in noisy flocks and forms massive roosts. The flocks may consist of hundreds or thousands of birds, and this species will also gather with parakeets and mynahs in plantations and mangroves. House crows return to their foraging grounds just prior to dawn. It is a very noisy species, with a rather dry, flat, toneless call described as a ‘kaaan-kaaan’ or ‘kaa-kaao’. During social interactions, they also make a wide range of softer, nasal calls.
House crows are generally regarded as monogamous, forming long-term pair bonds. However many individuals seem to be somewhat polygynandrous (promiscuous) when both males and females have multiple mates. The breeding season varies depending on the location. In India, it is from April to June, at the start of the wet season, while in East Africa it is between September and June. They are usually solitary nesters and typically nest close to human habitation. Nests are often in trees, but their untidy nests are also found on ledges of buildings, street lamps, and electricity pylons. 3 to 5 eggs are laid, very variable in shape and color, with an average of 4 per clutch. A female may produce two clutches per breeding season. Incubation is for about 15-17 days and is done by both parents, but at night it is mainly the female. Chicks stay in the nest for about 21 to 28 days, being tended to by both parents, on which they are dependent for several weeks more on leaving the nest.
