About These Birds
兀鹫
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.
Raggiana Bird-of-paradise
The raggiana bird-of-paradise is the national bird of Papua New Guinea, featured on the national flag and coat of arms. Males gather at traditional display trees to perform elaborate courtship dances, hanging upside down and shaking their spectacular flank plumes. Alfred Russel Wallace first described the species in 1873.
