Song & Call Comparison

A loud, whistled 'weet' or 'weeeet'. Males whistle a melodic series; contact call is a high nasal 'ny'. Capable of mimicry in captivity. Song is relatively simple but pleasant.

About These Birds
águia-de-cabeça-branca
The bald eagle is the national bird and symbol of the United States. Once endangered due to DDT pesticide use, it made a remarkable recovery and was removed from the endangered species list in 2007. These powerful raptors build the largest tree nests of any bird, some weighing over two tons.
caturra
The cockatiel is the smallest member of the cockatoo family and one of the most popular pet birds globally. These gentle, intelligent parrots can learn to whistle tunes and mimic sounds. Wild cockatiels are nomadic, traveling in flocks following food and water availability across the Australian outback.
