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.

Trumpeter Swan

El cisne trompetero es el ave más pesada nativa de América del Norte y el cisne más grande del mundo. Se reconoce por el completamente negro pico y el cuello muy largo. Cría en humedales del oeste de Canadá y el noroeste de Estados Unidos. Fue cazado casi hasta la extinción para usar sus plumas en la confección de plumas de escribir y su carne como alimento, pero se ha recuperado gracias a la protección.
