About These Birds
Labrador Duck
An extinct sea duck from eastern North America; the first North American bird to go extinct after European contact. Males had boldly contrasting black-and-white plumage with an unusual flattened soft-edged bill adapted for filter-feeding on mussel beds. Last confirmed sighting in 1878.
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.
