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.
Tufted Duck
El porrón moñudo es un pato buceador fácilmente reconocible por el largo mechón negro que cae desde la nuca del macho. El macho es de color negro brillante con los flancos blancos; la hembra es de color marrón oscuro con un mechón más corto. Ampliamente distribuido por Europa y Asia, habita en lagos, embalses y ríos de corriente lenta.
