About These Birds
Red-billed Teal
O pato-bico-vermelho é um pato dabbling de tamanho médio encontrado na África subsariana. É facilmente identificado pelo seu bico vermelho brilhante, que contrasta com a sua plumagem castanha mosqueada. Habita zonas húmidas de água doce, incluindo lagos, pântanos, charcas e rios de fluxo lento. É um dos patos mais abundantes e amplamente distribuídos em África, sendo encontrado desde o Senegal até à África do Sul, com movimentos sazonais.
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.
