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.
Red-breasted Merganser
O merganso-de-crista é um pato mergulhador de tamanho médio com um topete duplo desgrenhado que lhe dá uma aparência característica. Os machos têm cabeça verde iridescente com o topete desgrenhado, peito ruivo mosqueado e flancos cinzentos. É mais costeiro do que outros mergansos, criando frequentemente em costas marinhas e estuários. Hiberna em costas marinhas ao longo da Europa, Ásia e América do Norte. É amplamente distribuído no Hemisfério Norte.
