A systematic review of the mountain chickadee
Behle WH. 1956. A systematic review of the mountain chickadee. The Condor. 58(1):51-70
Being widely distributed over a diversified geographic area and thus being subject to varying environmental influences, mountain chickadees are composed of several populations of subspecific rank. However, the distinctness and geographic limits of some of these races have been in doubt. This study analyzes variation in the principal external characters of the species, determines more precisely the ranges of the races, and inquires as to the degree of differentiation and the relationships of the subspecies.
