A complex mimic: rattles, whistles, clicks, and squeaks mixed with imitations of other birds. Song is a continuous medley. Also gives harsh 'scheer' alarm and chattering.
Đại bàng Harpy
Rarely heard; emits mournful whistled screams 'wheee-oo' and low croaking grunts near the nest. Vocalizations poorly documented given its remote Amazonian habitat.

About These Birds
Common Starling
The common starling is famous for its murmurations — vast swirling flocks of thousands that create mesmerizing patterns in winter skies. An accomplished mimic, it can imitate other birds, car alarms, and phone ringtones. Introduced to North America by a group intent on establishing every bird mentioned by Shakespeare.
Đại bàng Harpy
The harpy eagle is among the most powerful raptors in the world, with talons as large as a grizzly bear's claws. It is the national bird of Panama. Deforestation poses the greatest threat to this species, as each breeding pair requires a vast territory of undisturbed forest.
