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.
Spur-winged Goose
El pato espolonado o ganso espolonado africano es el pato más pesado del África subsahariana. El macho tiene el plumaje negro iridiscente con el vientre blanco y la cara con carúnculas rojas. Su nombre alude a los espolones que tiene en los hombros de las alas, usados en combate. Habita en ríos, lagunas y pantanos de África, anidando en árboles o en el suelo.
