About These Birds
Ruddy-headed Goose
O ganso-de-cabeça-ruiva é o menor e mais raro dos gansos-da-patagónia, encontrado em prados úmidos da Terra do Fogo e nas Ilhas Malvinas. Tem cabeça e pescoço castanho-avermelhados característica que contrastam com o corpo barrado. As populações sofreram declínios severos, principalmente devido à predação introduzida de raposas e colonização de raposas nas Malvinas. É classificado como vulnerável com esforços de conservação focados na gestão de predadores.
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.
