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.
Black-billed Thrush
The Black-billed Thrush is a medium-sized, plain thrush widely distributed across northern and central South America from Colombia and Venezuela south to Bolivia and Brazil. It has olive-brown upperparts, streaked brownish-white underparts, and a distinctive dark bill. It inhabits forest edges, secondary growth, gardens, and open woodland, feeding on earthworms, insects, and berries.
