About These Birds
Philippine Duck
O pato das Filipinas é um pato dabbling de tamanho médio endémico das Filipinas. Apresenta uma coloração castanha avermelhada com cabeça ruiva e faixa ocular escura. Habita zonas húmidas de água doce, incluindo lagos, pântanos e arrozais em todo o arquipélago Filipino. É classificado como vulnerável devido à perda de habitat, caça e captura para o comércio de animais de estimação, com populações em declínio significativo nas últimas décadas.
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.
