About These Birds
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.
Common Blackbird
The common blackbird is one of Europe's most familiar and best-loved songbirds, celebrated for its rich, fluting song delivered from rooftop and treetop perches at dawn and dusk. Originally a shy woodland bird, it has colonized urban environments over the past two centuries and become one of the most successful urban adapters.
