About These Birds
Eastern Bluebird
The eastern bluebird is a beloved symbol of happiness in North America. Once declining due to habitat loss and competition from introduced species, populations recovered dramatically thanks to a massive citizen science nest box campaign. These gentle thrushes form loose winter flocks and huddle together in nest boxes during cold snaps.
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.
