About These Birds
Black-headed Nightingale-thrush
The Black-headed Nightingale-thrush is a medium-sized, secretive thrush with a black head, gray body, and bright orange bill and eye ring. It inhabits humid montane forests from Mexico through Guatemala and Honduras to Nicaragua, typically at elevations from 1,000 to 2,500 meters. It forages on the forest floor and in low undergrowth for fruits, berries, and invertebrates, producing a beautiful, melodious song.
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.
