True to its name, the grey-headed fish eagle feeds primarily on fish, but it will also take other prey, including reptiles, depending on local availability. To hunt for its fish prey, this eagle will usually perch on bare branches overlooking a body of water, before executing a short flight to snatch its prey once observed near or at the surface. Should the fish eagle’s catch be too big and heavy to be flown off, it will drag its prey onto the bank (2) (3) (5) (7).
The breeding season of the grey-headed fish eagle generally takes place between November and May. During this period, the grey-headed fish eagle is known to be rather noisy, often calling out at night (2) (3).The nest, which is constructed from sticks and lined with green leaves, is usually reused for several years in succession, and can be up to 1.5 metres wide and 2 metres deep. The nest is situated high up in the trees, (between 10 and 30 metres), and always near water. Usually one or two, occasionally three, pure white eggs are laid per mating couple. Incubation of the eggs is undertaken by both the male and female (2) (3) (5), and is likely to last between 45 to 50 days (8).
