About These Birds
Mottled Duck
El pato de Florida es un pato de tamaño mediano con plumaje marrón moteado en ambos sexos, similar al pato mexicano. Está estrechamente emparentado con el pato de collar y el pato negro americano, y los tres forman un complejo de especies estrechamente relacionadas. Se encuentra principalmente en Florida y la costa norte del Golfo de México, habitando marismas costeras y humedales de agua dulce.
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.
