White-Bellied Sea-Eagle (Haliaeetus leucogaster)
Hawks and eagles are largish to very large, predatory, hook-billed birds with powerful talons or claws, specialized for killing and tearing up vertebrate prey. They differ from the falcons in having generally blunter, more rounded wings and paler eyes (yellow red).
Eagles and vultures are specialized for soaring on air currents and hunt largely from the air, whereas the other hawks hunt from branches, but also sometimes soar; some species even hover over intended prey. Vultures feed mostly on carrion and have long barish necks for probing into carcasses. Members of the family make very large, stick pile nests in trees or on cliffs and the young give characteristic screaming calls.
There are 34 species in the Greater Sundas, including several migrants.

Habits: This magnificent eagle is frequently seen sitting very upright in a water-side tree, or on a cliff, or on fishing platforms. Soars and glides beautifully and gracefully with wings held in pronounced dihedral. Flying with slow, powerful wing-beats, it catches surfacing fish in spectacular dive, barely getting wet as fish is seized with talons. Builds huge nest of branches and twigs in tall tree and often used year after year.
