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.
Surf Scoter
O pato-fusco-americano é um grande pato marinho com o bico mais colorido e elaborado dos patos negros. Os machos têm plumagem preta com remendo branco no nuca e bico multicolorido com tubérculo. Cria em lagos e pântanos florestais do norte da América do Norte e Sibéria. Hiberna principalmente em costas marinhas ao longo das costas norte-americanas. As populações têm diminuído nalgumas regiões, levantando preocupações de conservação.
