The grey-headed fish eagle (Icthyophaga ichthyaetus) is a fish-eating bird of prey from Southeast Asia. It is a large stocky raptor with adults having dark brown upper body, grey head and lighter underbelly and white legs. Juveniles are paler with darker streaking. It is often confused with the lesser fish eagle (Icthyophaga humilis) and the Pallas's fish eagle. The lesser fish eagle is similar in plumage but smaller and the Pallas's fish eagle shares the same habitat and feeding behaviour but is larger with longer wings and darker underparts. Is often called tank eagle in Sri Lanka due to its fondness for irrigation tanks.
The grey-headed fish eagle was first described by Horsfield in 1841 as Falco ichthyaetus. It is included in the order Accipitriformes and the family Accipitridae, which includes most birds of prey except for the ospreys and falcons. Lerner & Mindell placed the grey-headed fish eagle in the subfamily Haliaeetinae, which includes the genera Haliaeetus (sea eagles) This paraphyletic group forms a close sister relationship with the subfamily Milvinae, based on the shared trait of basal fusion of the second and third phalanges found only in these two groups...

Possible
About 30% of wildlife watchers report a Gray-headed Fish-Eagle sighting in Yala National Park on a given day, based on 383 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 69th most-seen of the 220 birds we can rate there. Over three days the chance rises to about 70%, and over a week to about 90%, if each day is a fresh chance.

GBIF citizen-science records
It is estimated from how often the Gray-headed Fish-Eagle is recorded against all the birds logged in Yala National Park (383 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
