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.
Mandarin Duck
The mandarin duck is widely considered the most beautiful duck in the world. In East Asian culture, mandarin ducks symbolize love and fidelity because they form strong pair bonds. Unlike most ducks, mandarins nest in tree holes up to 9 meters above the ground, and day-old ducklings must leap to the ground.
