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.
オウギワシ
ハーピーワシは世界で最も強力な猛禽類の一つで、ハイイログマの爪ほどの大きさの鉤爪を持つ。パナマの国鳥。大規模な未撹乱の森林の生息地を必要とするため、森林破壊がこの種の最大の脅威。
