About These Birds
Belted Kingfisher
The belted kingfisher is unusual in that the female is more colorful than the male, sporting an additional rufous belly band. These noisy birds announce their territory with a distinctive rattling call. They excavate nesting burrows up to 2.4 meters deep into riverbanks using their heavy bills.
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.
