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.
Ashy Thrush
The Ashy Thrush is a Vulnerable thrush endemic to the Philippines, found in the forest understory of Luzon and a few adjacent islands. Weighing about 63g with a wingspan near 22.8cm, it has predominantly grey plumage with scaled underparts. Continuing forest loss on its island range poses a significant threat.
