About These Birds
Campbell Teal
A tiny flightless teal with dark brown plumage in females and males with greenish-black head. Endemic to Campbell Island, New Zealand. Nearly extinct; reintroduced after eradication of Norway rats from the island. Nocturnal; feeds on invertebrates at freshwater sources.
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.
