About These Birds
Madagascar Teal
El pato de Madagascar es una especie en peligro crítico de extinción endémica de Madagascar, donde persiste únicamente en unos pocos humedales costeros en el noroeste de la isla. Tiene plumaje marrón rojizo moteado con la cabeza rayada y un pico azulado. La destrucción del hábitat de los manglares y los humedales costeros, junto con la caza, ha reducido drásticamente su población.
African Pygmy-goose
El pigmeo africano o pato enano africano es el pato más pequeño de África y uno de los patos más pequeños del mundo. 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.
