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.
Pink-footed Goose
El ansar piquicorto es un ganso mediano de color gris-marrón con el pico corto de color negro con una banda rosada y las patas de color rosado-naranja. Cría en Islandia, Groenlandia y las islas Svalbard y pasa el invierno en las costas y campos cultivados del noroeste de Europa, especialmente en el Reino Unido y los Países Bajos. Es una especie de cría colonial en zonas montañosas.
