Habitat Comparison
Common Nightingale
Dense thickets, scrub, and undergrowth in deciduous woodland. Prefers areas with thick ground cover near water.
Harpy Eagle
Tropical lowland rainforests, requiring large tracts of continuous forest with tall emergent trees for nesting.
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.
Harpy Eagle
Rarely heard; emits mournful whistled screams 'wheee-oo' and low croaking grunts near the nest. Vocalizations poorly documented given its remote Amazonian habitat.
Geographic Range & Migration

Breeds in Europe and western Asia. Winters in sub-Saharan Africa. A long-distance migrant crossing the Sahara.
Harpy Eagle
Central and South America from southern Mexico through Brazil and northern Argentina. Range is shrinking due to deforestation.

About These Birds
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.
Harpy Eagle
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.
