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.
Falcated Duck
An elegant duck. Males have a large chestnut-and-green crested head, long drooping tertial feathers, and finely vermiculated grey body. One of Asia's most beautiful ducks; declining due to hunting. Breeds in Siberia and northeastern Asia; winters in East and Southeast Asia.
