As a breeder in Massachusetts, the Bicknell’s Thrush was historically restricted to the summit of Mount Greylock, the highest mountain in the state. The mountain remained an active center of Bicknell’s activity at least into the 1950s, when as many as ten nests were found, but that population had its apparent last gasp in 1972 (Veit & Petersen 1993). Though it had not yet been awarded full species status at the time of Atlas 1 and was still counted as a subspecies of the Gray-cheeked Thrush, the Bicknell’s Thrush was sought after at its traditional haunts among the fir trees on the summit of Mt. Greylock. Unfortunately, no Bicknell’s Thrushes were recorded during Atlas 1. During Atlas 2 a single singing Bicknell’s Thrush recorded in Barre was the only one recorded during Safe Dates in Massachusetts. This species appears to be extirpated as a breeding bird in Massachusetts.
