THE SUBSPECIES OF THE MOUNTAIN CHICKADEE

BY

JOSEPH GRINNELL

(Contribution From the Museum of Vertebrate Zoology of the University of
California)

Fieldwork was carried on by the California Museum of Vertebrate Zoology
during 1917 in the Inyo region of eastern California. In going over the
collection of birds obtained, the attention of the writer was arrested
by certain peculiarities evident in the Mountain Chickadees. Comparison
with series from the Sierras showed the Inyo birds to be paler colored
and longer tailed; and in order to appraise these differences in
taxonomic terms it became necessary to assemble material representative
of the entire range of the species, in so far as possible. The results
of the study thus undertaken are presented herewith.

The material involved in the inquiry has amounted to 464 skins of the
Mountain Chickadee, derived from the following sources other than the
Museum of Vertebrate Zoology: United States National Museum, through Dr.
Charles W. Richmond; United States Biological Survey, through Mr. Edward
W. Nelson; and the private collections of Messrs. Edward R. Warren,
Joseph and John W. Mailliard, G. Frean Morcom, Harry S. Swarth, and J.
Grinnell.

As of general interest, and in the nature of an introduction to the
systematic analysis to follow, i
