 Audubon: Field Notes
The Bicknell's thrush is one of 202 species that have fallen into the threatened red category, victimized in recent years by acid rain, deforestation, and development.
"The Bicknell's thrush has only an islandlike distribution in a sea of fir forests." The proposed ski expansion would mean the removal of about 55,000 trees from the thrush's habitat, which has already been designated an Important Bird Area (IBA) by Audubon New York.
Not surprisingly, the thrush has landed in the "red" zone on Audubon's 2002 WatchList, a roster of North American bird species.

 Audubon WatchList - Bicknell's Thrush
Bicknell's Thrush breeds in northeastern North America from the northern Gulf of the St. Lawrence and easternmost Nova Scotia southwest to the Catskills of New York in mountaintop forests dominated by balsam fir.
The Bicknell's Thrush is a medium-sized thrush with a heavily spotted breast and an olive-brown or brown back that contrasts with the hint of chestnut on its tail and wings.
Bicknell's differs from other spotted eastern thrushes as follows: Hermit has an all-red tail which it raises slowly when alarmed and a whiter eye-ring; Swainson's has cold olive-brown upperparts and a buffy face with buff-colored "spectacles"; Veery is uniformly reddish brown above, and is less spotted.

Related or Similar Species: Related or Similar Species: The thrush family is large, including the American Robin, all the spotted thrushes (Wood, Hermit, Swainson's, Gray-cheeked, Bicknell's, Veery), the Bluebirds (Eastern, Western, and Mountain), Varied Thrush, Townsend's Solitaire, plus the vagrant Rufous-backed Robin, Clay-colored Robin, Aztec Thrush, Fieldfare, Dusky Thrush, and Eye-browed Thrush.
The highly spotted juvenile American Robin can also be mistaken for the rare Aztec Thrush in southern Arizona, but such a rarity deserves a close look that reveals the overall mottled plumage and white patches on the folded wing.
Many other members of the thrush family occur in Europe and have not yet strayed to North America.

The result of Hale's work will be maps of suitable Bicknell's thrush habitats, which can be used for research on the bird's reproduction, migration and also as a baseline for future research.
Thanks to a $4,000 grant from the Garden Club of America, Hale and a contingent of assistants will visit the region's spruce fir forests, which Bicknell's thrush prefers for nesting.
Hale and his team will not only measure forest characteristics -- going so far as to count individual trees in an area -- but also match what they find with existing satellite imagery charts, thereby assessing what changes, if any, can be found in the state's spruce fir regions.

Ten years ago the 300 Club (300 bird species tallied in New Brunswick) had but 12 members, however things have changed dramatically in the last decade and now that number is probably somewhere between 50 and 100.

 Report #2 of the Massachusetts Avian Records Committee
Recent taxonomic changes by the American Ornithologists’ Union in its 1995 A.O.U. Checklist Supplement ( The Auk 112:819-830) have further resulted in the addition of Bicknells Thrush (split from Gray-cheeked Thrush), Spotted Towhee (split from Rufous-sided Towhee), Nelson’s Sharp-tailed Sparrow (split from Sharp-tailed Sparrow), and Bullock’s Oriole (split from Northern Oriole) to the state list.
This tabulation provides observers with a list of those species that require written, photographic, video, or sound recorded documentation whenever they are reported to regional compilers at Bird Observer or Bird News of Western Massachusetts.
Included with the June 1994 issue of Bird Observer was a copy of the Massachusetts Avian Records Committee State List that listed 450 accepted species for Massachusetts.
