Range expansion of Hermit and Swainson’s thrushes in the Southern Appalachians.
Westphal M, Simpson MB, Murdock N, Laughlin A. 2008. Range expansion of Hermit and Swainson’s thrushes in the Southern Appalachians.. The Chat. 72(4):126-132
The Hermit Thrush (Catharus guttatus) breeds in the western mountains and from Alaska across Canada to the New England states, and south in the higher peaks of the Appalachian Mountains to the Black Mountains of North Carolina. Recent range maps for the Swainson’s Thrush (Catharus ustulatus) show a similar range, but not extending as far south in either the eastern or western portions. In New England the range is limited to the more northern states and to the Appalachian Mountains. South of New England, Swainson’s Thrush is limited to the higher peaks, with the range extending to West Virginia, and more recently, Virginia. This report documents evidence of range expansion of these two species in the southern Appalachians.
