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.
Eurasian Magpie
The Eurasian magpie is one of the most intelligent animals on Earth and the first non-mammal demonstrated to recognize itself in a mirror. These bold corvids build elaborate domed nests of sticks and have a well-known attraction to shiny objects, though this reputation may be exaggerated.
