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.
Ruby-throated Hummingbird
The ruby-throated hummingbird is the only breeding hummingbird in eastern North America. These tiny birds beat their wings about 53 times per second and can fly backwards, sideways, and even briefly upside down. They make an extraordinary non-stop 800 km crossing of the Gulf of Mexico during migration.
