Song & Call Comparison
Common Myna
A noisy, cackling chatter and melodious whistling mixed together. An accomplished mimic of other birds and sounds. Gives repeated 'mee-ow' and harsh 'quarr' alarm 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.

About These Birds
Common Myna
Maina-comum (Acridotheres tristis) — 23-26 cm. Pássaro da família dos estorninhos originário do sul da Ásia, introduzido em numerosas regiões tropicais onde se tornou espécie invasora problemática. Plumagem castanho-escura com cabeça negra e marcas brancas nas asas. Vocaliza com grande variedade de sons. Onívoro oportunista extremamente adaptável.
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.
