White-bellied Sea Eagle
White-bellied sea eagles over Sundarbans creeks — identification, behaviour, and raptor neighbours.
Last updated
Haliaeetus leucogaster · IUCN Least Concern
Haliaeetus leucogaster is the flagship raptor of brackish India — a fish eagle that nests in tall mangroves and hunts where freshwater meets the bay. From a boat, adults lifting from a snag are one of the easiest “wow” moments that does not depend on tiger luck.
Where to watch
Scan open bends and dead timber on routes toward Sajnekhali and Sudhanyakhali. Pakhiralay village mornings reward birders with eagles, kites, and kingfishers when forest boats are not yet loud.
Bring binoculars (8×42 is fine). Telephoto from a stable seat beats leaning over the rail.
Raptors you will hear named
Reserve education lists brahminy kite, osprey, shikra, crested serpent eagle, short-toed eagle, and occasional oriented honey buzzard. Each fills a different perch height and prey niche — the Sundarbans sky is layered, not empty.
Ethics
Do not play recorded calls near nests. Flash sparingly. Winter (Nov–Feb) stacks migratory waders and raptors on top of residents — see wildlife overview.
Frequently asked questions
- How do I identify a white-bellied sea eagle?
- Adults are large with white head, breast, and tail, grey wings, and heavy yellow bill. In flight they show broad wings over open water and dead trees. Juveniles are darker and mottled — guides help separate them from brahminy kites at a distance.
- What other raptors share the same boat route?
- Brahminy kite, osprey, shikra, crested serpent eagle, and short-toed eagle are commonly listed for the Sundarbans. Oriental honey buzzard appears occasionally.
