Song & Call Comparison
águia-de-cabeça-branca
High-pitched, chattering whistle: a rapid 'kleek-kik-ik-ik-ik'. Surprisingly weak and thin for such a large raptor. Also gives a lower 'kwit-kwit' call near the nest.
European Robin
Exquisite, melancholic melody of thin whistled phrases, rising and falling softly. Rich, warbling song year-round; both sexes sing. Alarm call is a sharp 'tic-tic-tic'.

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.
European Robin
The European robin is one of the most beloved birds in Britain, where it is the unofficial national bird. Despite its friendly demeanor toward humans, robins are fiercely territorial against their own kind, singing year-round to defend territory. Their distinctive song is one of the first to be heard at dawn.
