About These Birds
Blue-winged Goose
O ganso-de-asa-azul é um ganso médio endémico das terras altas da Etiópia. Tem plumagem cinzenta com remendos de asa azuis, verdes e brancos marcantes, visíveis principalmente em voo. É encontrado em prados montanos, zonas húmidas e margens de lagos em altitudes entre 2.000 e 4.000 metros acima do nível do mar. A espécie está classificada como vulnerável devido ao seu alcance restrito, perda de habitat e perturbação humana. É facilmente perturbado e evita áreas com alta presença humana.
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.
