Size Comparison
Habitat Comparison
Gavião-real
Tropical lowland rainforests, requiring large tracts of continuous forest with tall emergent trees for nesting.
House Sparrow
Closely associated with human habitation. Found in cities, towns, farms, and any built environment. Rarely found far from people.
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.
House Sparrow
Monotonous series of chirping 'cheep' and 'chirrup' notes. Male gives 'chilp' song repeatedly. Flocks produce constant chirping chatter. No melodic song; purely functional calls.
Geographic Range & Migration
Gavião-real
Central and South America from southern Mexico through Brazil and northern Argentina. Range is shrinking due to deforestation.
House Sparrow
Native to Europe, Asia, and North Africa. Introduced to every continent except Antarctica, making it the most widely distributed wild bird.

House Sparrow
Males have grey crowns, chestnut napes, black bibs, and streaked brown backs. Females and juveniles are plain buffy-brown with a pale eyebrow stripe.
Short, stout, conical bill — black in breeding males, yellowish in non-breeding
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.
House Sparrow
The house sparrow is perhaps the most successful bird in the world at living alongside humans. Introduced to New York in 1851, it spread across North America within decades. Despite its global abundance, house sparrow populations have declined significantly in parts of western Europe.
