Melodious, repetitive cooing: a series of 'kowee-kowee-kowee' or 'woh-woh-woh-woh' phrases. Male sings from high exposed perches in cloud forest canopy. Evocative highland call.

About These Birds

シロエリハゲワシ

The griffon vulture is one of Europe's largest flying birds and a crucial scavenger in Mediterranean ecosystems. These social birds nest in large cliff colonies and can soar for hours using thermals without flapping. Vulture populations faced a crisis from the veterinary drug diclofenac, which proved fatal when consumed through contaminated carcasses.

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.
