About These Birds
Bar-headed Goose
O ganso-de-cabeça-listrada é famoso pelas suas extraordinárias migrações de alta altitude sobre o Himalaia, atingindo elevações de mais de 7.000 metros. É facilmente identificado pelas duas listras pretas características na cabeça branca. Cria em lagos de alta altitude no Tibete, Mongólia e países adjacentes. Hiberna nas planícies do subcontinente indiano. Tem fisiologia especialmente adaptada para respirar em altitudes extremas com hemoglobina que tem maior afinidade pelo oxigénio.
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.
