Fieldwork was carried on by the California Museum of VertebrateZoology during 1917 in the Inyo region of eastern California. Ingoing over the collection of birds obtained, the attention of the writerwas arrested by certain peculiarities evident in the Mountain Chickadees.Comparison with series from the Sierras showed the Inyo birdsto be paler colored and longer tailed; and in order to appraise thesedifferences in taxonomic terms it became necessary to assemble materialrepresentative of the entire range of the species, in so far aspossible. The results of the study thus undertaken are presentedherewith.
The material involved in the inquiry has amounted to 464 skinsof the Mountain Chickadee, derived from the following sources otherthan the Museum of Vertebrate Zoology: United States NationalMuseum, through Dr. Charles W. Richmond; United States BiologicalSurvey, through Mr. Edward W. Nelson; and the private collectionsof 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 thesystematic analysis to follow, it may be stated that Penthestes gambeliincluding its subspecies is throughout its range non-migratory, saveas a few individuals in pairs or small companies occasion
