About These Birds
White-cheeked Pintail

Distribuido por el Caribe, América del Sur y las Islas Galápagos, habita en lagunas costeras salobres, marismas y estanques de agua dulce.

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.
