About These Birds
Southern Pintail
O pato-dos-kerguélen é um pato dabbling pequeno restrito às ilhas subantárticas de Kerguélen e Crozet no Oceano Índico sul. Assemelha-se a uma versão menor do pato-real mas com plumagem mais escura. Existe como espécie isolada nestas ilhas remotas. Enfrenta ameaças de ratos e gatos introduzidos que predam os ninhos e filhotes. As populações são pequenas e limitadas a estas ilhas remotas, tornando a espécie vulnerável a qualquer catástrofe local.
African Pygmy-goose
O pato-pigmeu-africano é o menor pato africano e um dos menores da família dos anátidos. É encontrado em zonas húmidas tropicais de África subsariana. Os machos têm plumagem brilhante verde-escuro iridescente no dorso com flancos castanhos avermelhados e remendos brancos nas asas. Habita lagos, pântanos e áreas com vegetação aquática flutuante. Nidifica em ocos de árvore perto da água. A sua distribuição está ligada à presença de plantas aquáticas específicas.
