About These Birds
Greater White-fronted Goose
El ánsar careto o ganso careto mayor es un ganso mediano de color pardo con una llamativa mancha blanca en la frente y barras negras en el vientre.

A pesar de su aspecto similar al de un cisne, no está estrechamente emparentado con los cisnes verdaderos; los estudios genéticos sugieren que su pariente más próximo es el ganso de Nueva Holanda de Australia. Habita en humedales de Chile, Argentina, Uruguay y sur de Brasil.
