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.
Scarlet Macaw
The scarlet macaw is one of the most iconic tropical birds with its dazzling tricolor plumage. These highly intelligent parrots form lifelong pair bonds and can live over 75 years in captivity. They play an important ecological role as seed dispersers in Neotropical rainforests.
