About These Birds
Coscoroba Swan
The smallest swan and the only member of its genus, differing from true swans with a more goose-like head, red-pink bill and legs, and all-white plumage with black wingtips. Found in southern South America. Swims gracefully and grazes shoreline vegetation. Loud coscoroba call is distinctive.
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.
