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 Black Duck
El pato africano moteado es un pato de tamaño mediano de color marrón oscuro con motas blancas en el pecho y los flancos. Habita en ríos de rápido caudal, cascadas y arroyos de montaña en África central y meridional, siendo inusual entre los patos por su preferencia por aguas corrientes y turbulentas. También se encuentra en altitudes elevadas en las zonas montañosas de África oriental.
