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.
Red-breasted Goose
El barnacla cuellirrojo es un pequeño ganso con el plumaje llamativo de color negro, blanco y rojo-ladrillo. Cría en la tundra siberiana y migra al Mar Negro y el Caspio para pasar el invierno, con la mayor parte de la población invernando en Bulgaria y Rumanía. Está clasificado como vulnerable, con declives en sus poblaciones invernantes atribuidos a la caza y los cambios en el uso del suelo.
