Grey-headed Fish Eagle

Scientific Name: Haliaeetus ichthyaetus
Malay Name: Helang-Kanguk Besar
Chinese Name: 灰头鱼雕

Resident from the Indian subcontinent through southeast Asia, Sulawesi and Philippines.


Size: 69-74 cm

Adults with prominent greyish head, brown belly, brownish upperparts. Sub-adut browner with less distinct contrast. Distinguished from sub-adult White-bellied Sea Eagle by the presence of the distinct white vent and undertail coverts. Told apart the extirpated and highly unexpected Lesser Fish Eagle (a species that still resides in Johor that is reliant on pristine forest and big streams) by its bigger size and the presence of a white tail base.
