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.
White-winged Duck
El pato blanquibronceado o pato silvestre es una especie en peligro de extinción del sur y el sudeste de Asia. Tiene el plumaje negro brillante con la cabeza y el cuello de color blanco en el macho. Habita en densos bosques tropicales con ríos, lagunas y pantanos en India, Bangladés, Myánmar, Laos, Tailandia, Vietnam e Indonesia. La deforestación lo ha reducido a pequeñas poblaciones.
