About These Birds
Mallard
The mallard is the ancestor of most domestic duck breeds and the most abundant and widespread dabbling duck in the world. Males perform elaborate courtship displays including head-bobbing and whistle-grunt calls. Mallards are highly adaptable, thriving in both wilderness and urban environments.
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.
