  1. Indian Black Eagle – Ictinaetus malayensis - World of Birds of Prey Says:

    [...] Other than hawk conservancy trust, wikipedia also provide some good information about indian black eagle. wiki discribe this eagle asa large raptor at about 70-80cm in length. Adults have all-black plumage, with a yellow bill base (cere) and feet. The wings are long and pinched in at the innermost primaries giving a distinctive shape. The tail is also long, and shows faint barring. The wings are held in a shallow V in flight. Seen on hot afternoon, scouring the treetops for a nest, this bird is easily spotted by its jet black colour, large size, and a ‘characteristic’ slow flight, sometimes just above the canopy. Sexes are similar, but young birds have a buff head, underparts and underwing coverts. The wing shape helps to distinguish this species from the dark form of Changeable Hawk Eagle (Spizaetus cirrhatus). [...]
