The Bicknell's Thrush is of very high importance because of its extremely limited range, small overall population, and its extreme vulnerability to deforestation in its limited winter range. Identifying large and stable populations of this species, as well as determining its precise habitat and area requirements, especially sensitivity to silvicultural practices and other disturbances, will be important for conserving populations. Description Male: Upperparts olive-brown with a slightly more reddish tail and primaries, indistinct eye-ring. More

Bicknell's Thrush Habitat and Climate Change We have created a detailed map of the entire U.S. breeding habitat for Bicknell's Thrush. It was published in The Wilson Bulletin, a quarterly, peer-reviewed journal of ornithology in 2005. For the first time, we can reliably predict where this rare bird breeds and where it is likely to be absent. More
