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.
Spotted Whistling-duck
El pato silbador moteado es un pato silbador de Indonesia, Filipinas y Nueva Guinea, fácilmente reconocible por el plumaje marrón oscuro con manchas blancas en los flancos. Habita en bosques húmedos tropicales con estanques, pantanos y arrozales. Como todos los patos silbadores, tiene un llamado silbante característico y postura erguida. Está clasificado como casi amenazado.
