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.
Bismarck Island Thrush
The Bismarck Island Thrush is a thrush endemic to the Bismarck Archipelago, particularly New Britain and Bougainville. It has warm brown plumage typical of island thrushes in the Turdus genus. It forages on the forest floor and in trees for earthworms, fruits, berries, and invertebrates.
