About These Birds
Lesser White-fronted Goose
A small compact goose resembling Greater White-fronted Goose but with a more extensive white blaze, yellow orbital ring, and smaller bill. One of Europe's most endangered geese; wild population now extremely small. Breeds in Arctic Scandinavia and Siberia; winters in the Middle East and eastern Asia.
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.
