About These Birds
Red-breasted Goose
El barnacla cuellirrojo es un pequeño ganso con el plumaje llamativo de color negro, blanco y rojo-ladrillo. Cría en la tundra siberiana y migra al Mar Negro y el Caspio para pasar el invierno, con la mayor parte de la población invernando en Bulgaria y Rumanía. Está clasificado como vulnerable, con declives en sus poblaciones invernantes atribuidos a la caza y los cambios en el uso del suelo.

Habita en bosques húmedos tropicales con estanques, pantanos y arrozales. Como todos los patos silbadores, tiene un llamado silbante característico y postura erguida. Está clasificado como casi amenazado.
