About These Birds
White-cheeked Pintail
O pato das Bahamas, também chamado pato pico-branco, é um pato dabbling elegante nativo do Caribe, América Central e América do Sul. Caracteriza-se pelo seu bico cinza-azulado com base vermelha ou rosada brilhante e face e garganta brancas. Habita zonas húmidas costeiras, lagoas salinas e mangais. É comum em muitas ilhas caribenhas e regiões costeiras da América do Sul, com populações selvagens também estabelecidas nas Ilhas Canárias e noutras regiões.
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.
