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.
Plumed Whistling-duck
El pato silbador plumudo es un llamativo pato silbador australiano con largas plumas terciarias de color rosado que sobresalen de los flancos y crean un efecto plumado. Es de color ante-rosado con el dorso oscuro. Habita en praderas inundadas, pantanos y márgenes de lagos en el norte y el este de Australia. El macho produce un distintivo silbido durante el cortejo.
