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.
Ruddy Duck
O pato-de-cauda-rígida-americano é um pequeno pato de cauda rígida nativo da América do Norte. Os machos em reprodução têm cabeça preta, bico azul-celeste brilhante e corpo castanho-avermelhado. São famosos por exibições de corte elaboradas onde batem o bico contra o peito para fazer bolhas. Foram introduzidos na Europa onde hybridizam com o pato-de-cauda-rígida-europeu ameaçado. Esta hybridização levou a esforços de erradicação controversos em vários países europeus.
