Bicknell's Thrush
Catharus bicknelli (Ridgway, 1882)

New York State Distribution [-]
In New York, this species occupies mountain-top forests dominated by balsam fir and red spruce at elevations greater than about 3000 ft. in the Catskills and Adirondacks. In the Catskills, breeding is restricted to peaks generally above 3500 ft. within the forest preserve in southern Greene and central Ulster counties (Pierce-Berrin 2001). Occupied mountains in the Adirondacks are clustered around the High Peaks region in northwest Essex county, trending southwest (into central Hamilton county) to northeast into extreme southern Clinton County. The Adirondacks contain the largest area of suitable habitat in eastern North America, harboring perhaps 25% of the known breeding pairs (Atwood et al. 1996).

Global Distribution [-]
The breeding range in eastern North America is naturally fragmented into several "sky islands" of high elevation montane spruce/fir forests at the highest elevations in eastern New York (Catskill and Adirondack Mountains), formerly Massachusetts (Mount Greylock), the spine of the Green Mountains in central and northern Vermont, the White Mountains in northern New Hampshire and Maine, northern Cape Breton, Nova Scotia, higher elevations on the Gaspe Peninsula, and the interior highlands of New Brunswick (Rimmer et al. 2001). The wintering grounds are poorly documented; known from Hispaniola, Cuba, Puerto Rico, and St. Croix. The non-breeding stronghold almost certainly is the Dominican Republic (Rimmer 1996); not known from Central or South America (Ouellet 1993). Migration records encompass eastern coastal states of the U.S. and Bahamas (Ouellet 1993).
