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.
Papagaio-verdadeiro
The turquoise-fronted amazon is one of the most popular pet parrots in the world, prized for its ability to mimic human speech and its engaging personality. In the wild, these sociable parrots roost communally in large flocks and fly in pairs to feeding sites at dawn. Habitat loss and trapping for the pet trade threaten wild populations.
