The Whistling Kite (Haliastur sphenurus) is a medium-sized diurnal raptor found throughout Australia, New Caledonia and New Guinea. It ranges in size from 50 to 60 cm (20 to 24 in), with a wingspan between 123 and 146 cm (48 and 57 in). Males and females appear similar, with pale buff on the head, breast and tail, with browner wings and black flight feathers, but females are generally larger. It is named for its loud whistling call, which it gives in flight, while perched, and even while in the nest.Photo: Fir0002
