About These Birds
Hawaiian Duck
A medium-sized duck resembling a female Mallard, with mottled brown plumage and green speculum. Endemic to Hawaii; hybridizes with feral Mallards, threatening its genetic integrity. Found on freshwater wetlands of Kauai and other islands. Endangered; conservation focus on reducing hybridization.
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.
