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.
Andean Slaty Thrush
The Andean Slaty Thrush is a medium-sized thrush with a 21.4 cm wingspan, weighing around 54 grams. It inhabits humid montane forests along the Andes of South America. Males are dark slate-grey overall, while females are browner with streaked underparts.
