About These Birds
Egyptian Goose
O ganso-egípcio é um pato-de-terra grande e marcante nativo da África subsariana e Vale do Nilo. Tem plumagem castanho-mosqueado com uma mancha castanho-escuro ao redor do olho e um remendo escuro no peito. Foi sagrado para os antigos egípcios e frequentemente retratado em arte egípcia. As populações introduzidas estão agora estabelecidas em muitos países europeus, especialmente no Reino Unido e Países Baixos. Habita zonas húmidas, pradarias e áreas agrícolas.
