Northern Gannet
Open ocean and coastal waters. Breeds in dense colonies on steep rocky islands and sea stacks.
Song & Call Comparison

Rarely heard; emits mournful whistled screams 'wheee-oo' and low croaking grunts near the nest. Vocalizations poorly documented given its remote Amazonian habitat.
Northern Gannet
Loud, harsh 'urrah-urrah' grunting and croaking at breeding colonies on sea stacks. Also gives a softer 'karrr' in flight. Large colonies are extremely noisy during the breeding season.

Central and South America from southern Mexico through Brazil and northern Argentina. Range is shrinking due to deforestation.

About These Birds
Harpia Kartalı
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.
Northern Gannet
The northern gannet is a spectacular plunge-diver, folding its two-meter wingspan into an arrow shape to hit the water at up to 100 km/h. Air sacs under the skin and a reinforced skull protect it from the impact. Bass Rock in Scotland hosts over 150,000 gannets, the largest single colony of any seabird in the world.
