About These Birds
Greater Scaup
A medium-sized diving duck. Males have a rounded glossy green-tinged head, white flanks, and black breast; females are brown with white around the bill. Similar to Lesser Scaup but told apart by head shape and nail width. Found on large open water bodies.
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.
