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.
Musk Duck

El macho tiene un lóbulo de piel negra colgante debajo del pico que se agranda durante la estación reproductora, siendo único entre los patos. Es un buceador experto que se alimenta de invertebrados acuáticos. Los machos realizan demostraciones de cortejo elaboradas con salpicaduras y sonidos.
