Size Comparison
Habitat Comparison
Common Blackbird
Woodland, hedgerows, gardens, and parks. One of the most common garden birds across Europe.
Harpy Eagle
Tropical lowland rainforests, requiring large tracts of continuous forest with tall emergent trees for nesting.
Song & Call Comparison
Common Blackbird
Arguably Britain's finest songster: rich, flute-like phrases with deep, mellow quality. Sings persistently at dusk. Alarm is a sharp 'chook-chook'. Song includes liquid 'pew' notes.
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 Blackbird
Europe, Asia, and North Africa. Introduced to Australia and New Zealand. Northern populations are migratory.
Harpy Eagle
Central and South America from southern Mexico through Brazil and northern Argentina. Range is shrinking due to deforestation.

About These Birds
Common Blackbird
The common blackbird is one of Europe's most familiar and best-loved songbirds, celebrated for its rich, fluting song delivered from rooftop and treetop perches at dawn and dusk. Originally a shy woodland bird, it has colonized urban environments over the past two centuries and become one of the most successful urban adapters.
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.
