Indian Skimmer

The Indian Skimmer is the rarest and most range-restricted of the three skimmer species, confined to river systems of South and Southeast Asia. It shares the family's unmistakable bill shape but has suffered steep declines linked to habitat degradation along its riverine breeding grounds.

Appearance

Adults have a black cap and black upperparts contrasting with white underparts and a white collar around the hindneck, along with a yellow-orange bill tipped in black and orange-red legs.

Key field marks

• Black cap sharply defined against a white collar and underparts
• Yellow-orange bill with a black tip
• Orange-red legs
• Elongated lower mandible typical of skimmers
• Graceful, low flight over rivers while foraging

Similar species

The Indian Skimmer's range does not overlap with the Black or African Skimmers, so geography readily separates them; within its range it is distinctive and unlikely to be confused with any other bird due to its unique bill.

Habitat and range

Indian Skimmers are found along large, slow-flowing rivers, lakes, and estuaries across the Indian subcontinent and parts of Southeast Asia, with strongholds along major river systems in India, Nepal, Bangladesh, and Myanmar. They depend on wide river channels with exposed sandbars for both foraging and breeding.

The species has disappeared from large parts of its historic range due to river damming, sand mining, and pollution, leading to its current fragmented and declining distribution.

Behavior

Indian Skimmers forage in the same manner as other skimmers, flying low over calm river water with the lower mandible slicing the surface to detect and seize small fish.

Voice

Calls are sharp, tern-like notes, given especially in alarm near nesting colonies on exposed sandbars.

Nesting and breeding

Breeding occurs colonially on riverine sandbars exposed during the dry season, with two to four eggs laid in a shallow scrape. Nesting success is heavily threatened by disturbance from fishing, sand extraction, livestock grazing, and unpredictable water releases from upstream dams.
