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.
