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.
King Eider
O êider-real é um pato marinho do Ártico com um dos ornamentos faciais mais elaborados de qualquer pato. Os machos têm um escudo frontal laranjas-amarelo proeminente e padrão branco, preto e verde conspícuo. Habita costas árticas e tundra no verão, movendo-se para costas abertas no inverno. É uma espécie circumpolar que nidifica na tundra ártica e é sensível a alterações climáticas que afetam o seu habitat de gelo marinho.
