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. Tiene un amplio rango de cría en la tundra ártica del hemisferio norte y migra a zonas templadas de Europa, Asia y América del Norte para pasar el invierno, donde a menudo se reúne en grandes bandadas en campos agrícolas.

Cría en las turberas de Tierra del Fuego y las Islas Malvinas y migra al norte en invierno hasta las pampas de Argentina. Tiene la cabeza y el cuello de color castaño rojizo brillante. Su población ha declinado drásticamente por la depredación por visones introducidos y la caza.
