Whistling Kite

The whistling kite is a medium-sized diurnal raptor found throughout Australia, New Caledonia and much of New Guinea. Also called the whistling eagle or whistling hawk, it is named for its loud whistling call, which it often gives in flight. Some authorities put this species in the genus Milvus, despite marked differences in behaviour, voice and plumage between this species and other members of that genus.
