About These Birds
Lesser White-fronted Goose
O ganso-pequeno-de-testa-branca é o menor ganso do Paleártico. Assemelha-se ao ganso-de-testa-branca mas é menor, com anel ocular amarelo mais proeminente e mancha branca que se estende mais para cima na testa. Cria em tundra montanhosa na Sibéria. Hiberna principalmente na região do Mar Cáspio e Ponto. As populações sofreram declínios drásticos e está classificado como vulnerável. A caça acidental durante a caça ao ganso-de-testa-branca é uma ameaça significativa.
