Size Comparison
Habitat Comparison
Common Kestrel
Open country including farmland, grasslands, moorland, and urban areas. Common along motorways and in cities across Europe.
Harpy Eagle
Tropical lowland rainforests, requiring large tracts of continuous forest with tall emergent trees for nesting.
Song & Call Comparison
Common Kestrel
A shrill, repeated 'kee-kee-kee-kee' or 'kik-ik-ik', especially near nest. Alarm call is a nasal chattering. Generally less vocal than larger falcons. Calls ring clearly in open country.
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 Kestrel
Europe, Asia, and Africa. One of the most common and widespread raptors in the Old World.
Harpy Eagle
Central and South America from southern Mexico through Brazil and northern Argentina. Range is shrinking due to deforestation.

About These Birds
Common Kestrel
The common kestrel is Europe's most abundant falcon, famous for its ability to hover motionless in the wind while scanning for prey. Research has shown kestrels can see ultraviolet light, allowing them to detect vole urine trails that reflect UV. The species has adapted remarkably well to urban environments.
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.
