African Pygmy-goose

Tiene plumaje de color verde oscuro y blanco con el cuello de color castaño rojizo. Habita en lagunas tranquilas, estanques y pantanos con abundante vegetación flotante, especialmente lirios de agua, en África subsahariana.
White-headed Duck
El pato malvasía es un pato de cola tiesa en peligro de extinción con el macho de llamativa cabeza blanca y cuello negro con el pico azul brillante hinchado en la base. En el pasado fue cazado intensamente y su hábitat fue drenado, lo que lo llevó al borde de la extinción en el siglo XX. Gracias a esfuerzos de conservación intensivos, sus poblaciones se han recuperado parcialmente en el Mediterráneo.
