About These Birds
Egyptian Goose
El ganso del Nilo o oca egipcia es un grande y agresivo pato del África subsahariana y el Valle del Nilo. Tiene plumaje leonado con manchas marrones en el pecho y las alas, y un llamativo parche marrón alrededor del ojo. Ha sido introducido en Europa, donde ha establecido poblaciones silvestres en el Reino Unido, los Países Bajos y Alemania. Es muy territorial durante la cría.
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.
