Is the southern Appalachian black capped chickadee endangered?

Answer 1

The black capped chickadee reaches the southern limit of its range in the Plott Balsam range in the Blue Ridge mountains in North Carolina, occuring at altitudes of 2800 feet or more. It is replaced at lower elevations by the nearly identical but slightly smaller Carolina chickadee, and, where the ranges overlap, some hybridization may occur. Never common in the NC mountains, but considered "fairly common" there, the black capped chickadee is considered a species of "Least Concern" by the IUCN.
