The wing-tips almost reach the all dark tail helping to distinguish this species from the larger Gray-headed Fish-Eagle. The lack of contrast between its gray head and brownish mantle also supports the identification as a Lesser Fish-Eagle. The light eye and plain upperparts indicate this is an adult. Classified as "near threatened" this Fish-Eagle has an uncertain world population currently estimated at 10,000-50,000 adults. However the species is uncommon throughout its range and appears to be declining. Habitat loss and pesticides are possible causes of its decline. Two subspecies are recognized. Birds in India are I. h. plumbea. The smaller nominate race replaces it in extreme Southeast Asia. Canon PowerShot SX50 HS.
