Watchlist Species Search

As an extreme habitat specialist, the Bicknell’s Thrush has a very limited range, breeding primarily in high elevation stunted montane spruce-fir forests of the northeastern U.S. and southeastern Canada.

The Canada Warbler inhabits shady forest undergrowth year round, making this species vulnerable to forest loss. Canada Warblers spend the majority of the nonbreeding season in the northern Andes, which is among the most threatened in the world, having experienced a 90% loss of forest due to agricultural expansion (cattle, coffee, coca) and fuel wood production.
