Indian Cormorant

Identification

The Indian cormorant is a medium-sized bronze-brown waterbird with distinctive blue eyes that set it apart from similar species. Its plumage is scalloped in black on the upper parts, and it lacks a crest. The head is notably small and slightly peaked, with a long, narrow bill that terminates in a hooked tip—perfect for gripping slippery prey. Non-breeding birds display bare yellow facial skin, while breeding adults develop a short white ear tuft. Some individuals show white on the throat, though this marking is restricted below the gape, distinguishing it from the much larger great cormorant. Juveniles and non-breeding adults tend to be browner overall, while sexes are otherwise similar in appearance.

Range & Habitat

This gregarious cormorant is found primarily along the inland waters of the Indian subcontinent, ranging from Sri Lanka's northern regions through peninsular India and extending northeast to Assam. Its distribution stretches eastward into Thailand, Burma, and Cambodia, with populations also present in Sind to the west. Rather than coastal waters, the Indian cormorant favors inland rivers, large wetlands, estuaries, and mangrove systems. They breed very locally in mixed-species breeding colonies, typically establishing nests in the forks of partially submerged trees or those growing on islands, often organizing in dense colonies with multiple tiers of nests.

Behaviour & Diet

The Indian cormorant is an accomplished fish hunter that typically makes short dives to capture its prey. Remarkably social hunters, these birds often fish communally in groups, coordinating their efforts to form a broad front that drives fish into a corner, making capture easier for the entire flock. Breeding occurs seasonally, with timing dependent on rainfall and water conditions. In northern India, breeding extends from July through February, while in Sri Lanka it occurs between November and February. Nests consist of twigs arranged in platform structures, with clutches typically containing three to five bluish-green eggs bearing a chalky surface.

Best Time & Places to See It

The best opportunities to observe Indian cormorants are during their breeding season—July to February in northern India and November to February in Sri Lanka—when they gather in visible colonies. Look for them on inland rivers, large wetlands, and estuarine systems throughout the Indian subcontinent, particularly in peninsular India and extending northeast toward Assam. They prefer areas where they can gather in communal fishing groups, making waterbird hotspots and protected wetland reserves ideal locations for encounters. Their gregarious nature means that when found, they are often present in substantial numbers.

Photography Tips

Capture the Indian cormorant's distinctive blue eyes and small, peaked head as your primary subjects—these features are key identification marks. Look for opportunities to photograph cooperative hunting behavior, where groups form broad fronts in the water. The breeding season offers additional photographic interest with birds displaying their short white ear tufts and bare yellow facial skin. Early morning light on inland wetlands will accentuate the bronze-brown plumage and black scalloping. Photographing nesting colonies during breeding season can yield compelling images of the dense, multi-tiered nest arrangements, though approach carefully to avoid disturbing these sensitive breeding sites.
