The Indian cormorant was formally described in 1826 by English naturalist James Francis Stephens and given the current binomial name Phalacrocorax fuscicollis. The specific epithet combines the Latin fuscus meaning "dusky" or "brown" with the Modern Latin -collis meaning "-necked". The species is monotypic: no subspecies are recognised.
This cormorant fishes gregariously in inland rivers or large wetlands of peninsular India and the northern part of Sri Lanka. It also occurs in estuaries and mangroves but not on the open coast. They breed very locally in mixed species breeding colonies. They extend north-east to Assam and eastward into Thailand, Burma and Cambodia.
The breeding season is July to February but depends on rainfall and water conditions. In northern India, they breed from July to February and in Sri Lanka, between November and February. The nest is a platform of twigs placed in the forks of partially submerged trees or of those growing on the islands. The nests are similar to those of other Indian cormorants, storks or waterbirds in dense colonies, often with several tiers of nests. The usual clutch is three to five eggs which are bluish green and with a chalky surface.
The Indian cormorant makes short dives to capture the fish and a group will often fish communally, forming a broad front to drive fish into a corner.
