About These Birds
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.
Goosander
O merganso-grande é o maior merganso e um dos maiores patos mergulhadores de água doce. Os machos têm cabeça verde iridescente escura sem topete, pescoço branco e corpo predominantemente branco. O bico serrilhado e longo é adaptado para capturar peixes. Cria em buracos de árvore em florestas ripícolas junto a rios e lagos limpos. Hiberna em rios, lagos e costas marinhas. É um indicador da qualidade da água, sendo sensível à poluição e degradação do habitat.
