About These Birds
American Black Duck
El pato negro americano es un gran pato de color marrón muy oscuro con una cabeza más clara y un llamativo espéculo alar púrpura. Habita en humedales del este de Norteamérica y se está hibridando cada vez más con el pato de collar introducido en su rango, lo que representa una amenaza para su pureza genética. Prefiere marismas costeras, pantanos boscosos y lagos tranquilos.
Maned Duck
El pato australiano selvático es un pato terrestre peculiar endémico de Australia, donde vive principalmente en pastizales y bosques abiertos, alejado del agua más que otros patos. Tiene la cabeza y el cuello de color chocolate oscuro con un marrón veteado y crema en el cuerpo. Pasta hierba con el pico corto. Anida en huecos de árboles, a veces lejos del agua.
