Indian jungle crow
The Indian jungle crow (''Corvus culminatus'') is an all-black species of jungle crow found in the plains of India where it is very common and readily distinguished from the house crow which has a grey neck. Often grouped along with other crow species in the region, it differs in its voice from the large-billed crow found in the higher elevations of the Himalayas and the eastern jungle crow (''Corvus levaillantii'') overlaps in the eastern part of its range. In appearance it cannot be easily distinguished from either of these species although the plumage tends to be more uniformly glossed in purple and has a longer bill with a fine tip and an arched culmen. The Himalayan species has a slightly wedge-shaped tail unlike the rounded tail of the Indian jungle crow.
==Description==
This glossy all-black crow has a heavy black bill with an arching culmen (upper edge of the mandible) and has a fine tip. The feathers have a purple gloss throughout. The tail of the Indian jungle crow is rounded and the legs and feet are stout. The Himalayan ''japonensis'' (in this sense including western ''intermedius'' and eastern ''tibetosinensis'') has a slightly wedge-shaped tail and a voice is a guttural and grating ''graak'' (''intermedius'') or a hoarse ''kyarrh'' (''tibetosinensis''). The calls of the Indian jungle crow are not unlike that of the house crow but are harsher. In Sri Lanka, the house crow lacks the light grey neck but the neck is slimmer than in the jungle crow. The sexes are indistinguishable.
