Description

The whistling kite ranges in size from 50–60 cm (20–24 in), with a wingspan between 123–146 cm (48–57 in). Weights range from 380–1,050 g (13–37 oz) an average of 600g-750g for males and 750g-1000g for females. As with most raptors, females are larger and heavier than males; though there is considerable overlap between the sexes, females can be up to 21% larger and 42% heavier. Southern birds are also larger than those found in the tropics. Male and female plumages are the same. Adult birds are a pale buff on the head, breast and tail, with browner wings and black flight feathers. Immature birds are a heavily streaked reddish-brown with prominent pale spots on the wings. Throughout their lives, whistling kites have bone-colored legs and feet, which are unfeathered. Overall, the whistling kite looks small-headed and long-tailed, with wingtips falling well short of the tail tip when the bird is perched. Though its legs are short, the bird walks easily on the ground. Whistling kites soar on slightly bowed wings, with their long flight feathers often well-splayed. The striking pattern on their underwings is distinctive.

Whistling Kite consume a wide range of prey including mammals, birds, fish, reptiles, amphibians, insects, and carrion. They adapt by scavenging or hunting, taking food from ground, water, or air, and even pirating from other birds. Whistling Kite exploit various opportunities like roadkill and fires to find meals.
Habitat
Whistling Kite primarily inhabits open or lightly wooded areas, favoring environments in proximity to water sources. These birds are common across a range of elevations, from sea level up to 1,400 meters, although they mostly reside below 800 meters elevation. Their preferred habitats include terrestrial and marine wetlands, as well as human-modified landscapes like paddocks and airstrips, provided there is water nearby. Whistling Kite nests in various woodland types, often near rivers and in monsoon rainforest regions. While largely sedentary, certain populations exhibit nomadic or migratory behaviors within broad geographical regions, particularly in response to seasonal changes.
