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.
Ringed Teal
A small ornate teal. Males have a pink-chestnut breast, grey flanks, and grey-brown back with dark green speculum; females are brown with distinctive white eye-ring and spotted flanks. Found in subtropical forests of South America. Nests in tree cavities. Perches and roosts in trees.
