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.
Taiga Bean Goose
El ansar campestre es un ganso de cuello largo de color marrón oscuro con el pico negro y naranja. Cría en la taiga y la tundra del norte de Europa y Asia, y migra al sur para pasar el invierno en campos de cultivo y praderas de Europa occidental y Asia oriental. Se alimenta principalmente de hierbas, cereales y raíces en sus zonas de invernada.
