Size Comparison
Habitat Comparison
Gavião-real
Tropical lowland rainforests, requiring large tracts of continuous forest with tall emergent trees for nesting.
Ruby-throated Hummingbird
Deciduous and mixed forests, woodland edges, gardens, and parks with flowering plants. Migrates across the Gulf of Mexico.
Song & Call Comparison
Gavião-real
Rarely heard; emits mournful whistled screams 'wheee-oo' and low croaking grunts near the nest. Vocalizations poorly documented given its remote Amazonian habitat.
Ruby-throated Hummingbird
Soft, high-pitched chattering and twittering 'chee-dit'. Also produces a thin 'tik' call in flight. Wing beats create an audible high-pitched humming buzz during hovering.
Geographic Range & Migration
Gavião-real
Central and South America from southern Mexico through Brazil and northern Argentina. Range is shrinking due to deforestation.

About These Birds
Gavião-real
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.
Ruby-throated Hummingbird
The ruby-throated hummingbird is the only breeding hummingbird in eastern North America. These tiny birds beat their wings about 53 times per second and can fly backwards, sideways, and even briefly upside down. They make an extraordinary non-stop 800 km crossing of the Gulf of Mexico during migration.
