About These Birds
Yellow-billed Pintail
O pato amarelo-castanho é um pato dabbling encontrado na América do Sul e nas ilhas da Geórgia do Sul. Apresenta uma plumagem castanha mosqueada com a cabeça estriada e um espelho alar verde-dourado marcante. É amplamente distribuído em zonas húmidas andinas e patagónicas, desde a Colômbia e Venezuela até à Terra do Fogo. As populações das ilhas da Geórgia do Sul são isoladas e foram propostas como subespécie separada.
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.
