About These Birds
Red-billed Teal
A medium-sized teal with a distinctive red bill, dark brown cap and back, pale cheeks, and fine barring on the flanks. Common in sub-Saharan Africa, especially eastern and southern Africa. Nomadic; follows seasonal rainfall. One of Africa's most abundant ducks.
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.
