Size Comparison
Habitat Comparison
Atlantic Puffin
Breeds on grassy cliff tops and offshore islands. Spends winter entirely at sea in the North Atlantic.
Gavião-real
Tropical lowland rainforests, requiring large tracts of continuous forest with tall emergent trees for nesting.
Song & Call Comparison
Atlantic Puffin
At burrow gives a low, moaning 'arr-arr-arr' growl. Silent at sea. At breeding colonies produces a series of grunting croaks. Chicks give soft peeping calls.
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
Atlantic Puffin
North Atlantic from eastern Canada and northeastern United States to Iceland, Norway, and northwest Russia.
Gavião-real
Central and South America from southern Mexico through Brazil and northern Argentina. Range is shrinking due to deforestation.

About These Birds
Atlantic Puffin
The Atlantic puffin, often called the clown of the sea, is a charismatic seabird that nests in burrows on northern sea cliffs. Puffins can carry up to a dozen fish crosswise in their beaks at once thanks to backward-facing spines on their palate. Climate change and overfishing are threatening their food supply, leading to population declines.
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.
