Whistling kite is a very vocal bird, it can whistle in flight or while perched on a branch. Pairs constantly call to each other.
They are graceful gliders often flying low searching for live or dead prey. They sometimes take fish from the surface of the water. They also catch reptiles, insects, and small mammals.
The whistling kite takes prey in its talons and then transfers it to its bill to eat.
