Size Comparison
Habitat Comparison
Shared Habitats
None
Common Starling only
Harpy Eagle only
Common Starling
Open countryside, farmland, parks, and urban areas. Forms enormous communal roosts in winter, especially in urban environments.
Harpy Eagle
Tropical lowland rainforests, requiring large tracts of continuous forest with tall emergent trees for nesting.
Song & Call Comparison
Common Starling
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.
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
Common Starling
Native to Europe, western Asia, and North Africa. Introduced to North America, South Africa, Australia, and New Zealand.
Harpy Eagle
Central and South America from southern Mexico through Brazil and northern Argentina. Range is shrinking due to deforestation.

Long, pointed bill — yellow in breeding season, dark in winter

Slate-black upperparts and head with a pale grey breast and white underparts with black barring. A distinctive split grey crest rises when the bird is alarmed.
Massive dark hooked bill, one of the largest of any eagle
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.
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.
