About These Birds
นกอินทรีฮาร์ปี
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.
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.
