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.
Resplendent Quetzal
The resplendent quetzal was considered divine by the Maya and Aztec civilizations, associated with the feathered serpent god Quetzalcoatl. Its iridescent green plumage and long tail streamers make it one of the most beautiful birds in the world. Guatemala's currency is named after this bird.
