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.
Keel-billed Toucan
The keel-billed toucan is the national bird of Belize and one of the most recognizable birds in the Neotropics. Its oversized bill, which can be a third of its body length, is actually very light due to its hollow honeycomb structure. Toucans roost communally, with up to six adults squeezing into a single tree cavity.
