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.
Wandering Whistling-duck
El pato silbador vagabundo es un pato silbador de distribución amplia en las regiones tropicales de Asia y el Pacífico, desde Borneo e Indonesia hasta Nueva Guinea y Australia. Tiene plumaje castaño con blanco y negro en los flancos. Habita en humedales tropicales, pantanos, lagunas, estanques y arrozales. Es una especie nómada que sigue las lluvias en busca de humedales.
