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.
Alpine Thrush
The Alpine Thrush is a large thrush weighing nearly 94 g with a 27.7 cm wingspan, found in high-altitude forests and scrub across Asia. It forages on the ground for invertebrates, berries, and fallen fruit.
