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.
