Key Field Marks
- Size & shape: A huge waterbird, around 5 feet (1.5 m) long with an 8-foot (2.5 m) wingspan, and the massive long bill and throat pouch typical of pelicans.
- Plumage: Mostly white to grayish-white body with a grayish tinge, especially on the neck, back, and wings; a short, shaggy crest on the nape in breeding adults; blackish flight feathers visible in flight, contrasting with paler wing coverts.
- Bare parts — the key mark: The bill is pale pinkish-gray to bluish-gray with a purplish, spotted or blotched pouch, most vivid in the breeding season — the source of the name. Legs are dull pinkish-gray.
- Behavior: Often seen soaring on thermals in loose flocks with neck retracted (S-shaped) in flight; feeds by scooping fish while swimming, sometimes cooperatively in groups.
Separating It From Similar Species
- Great White Pelican — larger, cleaner white plumage overall (especially in non-breeding), with a plain yellowish/orange (not spotted) pouch and pink-tinged legs; mainly found farther west/north and in Africa.
- Dalmatian Pelican — much larger and shaggier-headed, with a grayer overall plumage, an orange-red lower mandible pouch (not purple-spotted), and curly nape feathers; more northern/wintering distribution in parts of Asia.
- The combination of medium-large size, grayish plumage, and a spotted purple-gray pouch is diagnostic for Spot-billed Pelican within its Asian range.
Habitat, Range & Season
Resident and locally migratory across the Indian subcontinent and parts of Southeast Asia, including India, Sri Lanka, and scattered populations in Cambodia and Vietnam (with a much-reduced historical range across mainland Southeast Asia). Favors large freshwater lakes, reservoirs, marshes, and estuaries, often nesting colonially in trees near water. Present year-round in most of its range, with some local dispersal outside the breeding season.
Voice
Generally silent away from breeding colonies; at nesting colonies gives low grunting and bill-clattering sounds typical of pelicans.
