About These Birds
American Robin
The American robin is widely regarded as a harbinger of spring across North America. Despite its name, it is a true thrush unrelated to the European robin. American robins produce two to three broods per year and are among the earliest birds to sing in the morning chorus.
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.
