About These Birds
Belted Kingfisher
The belted kingfisher is unusual in that the female is more colorful than the male, sporting an additional rufous belly band. These noisy birds announce their territory with a distinctive rattling call. They excavate nesting burrows up to 2.4 meters deep into riverbanks using their heavy bills.
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.
