A medium-sized diving duck. Males have a glossy black head and breast, white flank stripe, and a grey bill with a white ring near the tip; females are brown. Named for an inconspicuous brown neck ring. Common in North America. Dives for aquatic plants and invertebrates.
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.
