Size Comparison
Habitat Comparison
Blue Jay
Deciduous and mixed forests, parks, and suburban areas. Highly adaptable to human-modified landscapes.
Harpy Eagle
Tropical lowland rainforests, requiring large tracts of continuous forest with tall emergent trees for nesting.
Song & Call Comparison
Blue Jay
A harsh, ringing 'jaay-jaay-jaay'. Also mimics Red-tailed Hawk and other species convincingly. Gives soft, liquid 'bell' calls and gurgling whispers in flocks.
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
Blue Jay
Eastern and central North America from southern Canada to the Gulf Coast. Some populations migrate irregularly.
Harpy Eagle
Central and South America from southern Mexico through Brazil and northern Argentina. Range is shrinking due to deforestation.

About These Birds
Blue Jay
The blue jay is a bold, intelligent member of the corvid family known for its striking plumage and loud calls. Blue jays are important dispersers of oak trees, as they cache thousands of acorns each autumn. Their complex social behavior includes mimicking the calls of hawks to scare other birds from feeders.
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.
