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.
Pink-headed Duck
Possibly extinct; a distinctive large diving duck formerly found in the Ganges plains of India and Myanmar. Males had a deep pink head and neck contrasting with dark chocolate-brown body. Last confirmed sightings in the 1940s. One of Asia's greatest bird mysteries.
