Size Comparison
Habitat Comparison
Great Cormorant
Coasts, estuaries, lakes, rivers, and reservoirs. Nests in colonies in trees, on cliffs, or on the ground.
Gavião-real
Tropical lowland rainforests, requiring large tracts of continuous forest with tall emergent trees for nesting.
Song & Call Comparison
Great Cormorant
Deep, guttural grunts and 'karrr' calls at colonies. Bill-clicking and hissing in threat displays. Silent at sea. Colonial noise can be deafening during the breeding season.
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.
Geographic Range & Migration
Great Cormorant
Very wide range across Europe, Asia, Africa, and Australasia. One of the most widespread cormorant species.
Gavião-real
Central and South America from southern Mexico through Brazil and northern Argentina. Range is shrinking due to deforestation.

About These Birds
Great Cormorant
The great cormorant is one of the most widespread seabirds in the world. Unlike most waterbirds, cormorants lack fully waterproof plumage, leading to the iconic pose of standing with wings spread open to dry. In Asia, cormorants have been used by fishermen to catch fish for over a thousand years.
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.
