About These Birds
Wood Duck
El pato de Carolina o pato de los bosques es uno de los patos más coloridos de América del Norte, con el macho de plumaje multicolor de vivos colores y una cresta de varios tonos. Cría en bosques caducifolios húmedos cerca de ríos y estanques, anidando en cavidades de árboles. Fue sobreexplotado a finales del siglo XIX, pero se recuperó tras medidas legales de protección.
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.
