About These Birds
Lesser White-fronted Goose
El ánsar chico o ganso careto chico es el más pequeño de los gansos árticos y está en peligro de extinción. Tiene el mismo patrón que el ánsar careto pero más pequeño, con un anillo ocular amarillo llamativo. Cría en la tundra del norte de Eurasia y migra al sur para pasar el invierno. Su población ha declinado drásticamente en las últimas décadas por la caza excesiva y la pérdida de hábitat.

Tiene plumaje de color verde oscuro y blanco con el cuello de color castaño rojizo. Habita en lagunas tranquilas, estanques y pantanos con abundante vegetación flotante, especialmente lirios de agua, en África subsahariana.
