About These Birds
Black Swan
The black swan was once considered impossible by Europeans who believed all swans were white, making it a famous philosophical example of inductive reasoning failure. It is the state emblem of Western Australia. Black swans form lifelong pair bonds and both parents share in incubation and care of cygnets.
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.
