About These Birds
Brazilian Teal
A small compact teal with brown plumage, red bill and legs, and males with a distinctive powder-blue speculum. Common in tropical lowland South America. One of the most widespread ducks in Brazil. Found in a wide range of wetland types from flooded forest to open lakes.
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.
