Song & Call Comparison

Common Nightingale
Considered Europe's finest songster: an extraordinarily rich, loud, flute-like melody of bubbling trills, slow whistles, and a distinctive crescendo 'lu-lu-lu'. Sings day and night.

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.
Common Nightingale
The common nightingale is celebrated as one of the finest songsters in the bird world, inspiring poets from Homer to Keats. Males sing complex phrases of over 250 different types, often at night during breeding season. Despite its famous song, the nightingale is a plain-looking bird that skulks in dense vegetation.
