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.
Bicknell's Thrush
Bicknell's Thrush is a vulnerable, secretive thrush that breeds in dense montane spruce-fir forests in the northeastern United States and adjacent Canada. It has brown upperparts, spotted buff-white underparts, and a faint yellowish base to the lower mandible. It winters in the Caribbean, particularly Hispaniola, where it is threatened by habitat loss at both ends of its migration.
