A. Good 1980 Mt Chickadee N Slope Whaleback, 9 mi. N + 5 mi. E summit Mt. Shasta, 1800 m., Siskiyou Co., Calif. [T. 43N, R. 2W, SE¼ sec. 20] 43 2 July Got here late in afternoon when birds are usually quiet. However there are very large numbers of Chickadees apparent anyway. Probably a function of their preference for small conifers. 3 July Chickadees very common, especially in younger stands of firs mixed w/ chaparral vegetation. Song seems normal although Bob Zink thinks that the last note is a bit higher than the second. This may be true but I can't decide one way or the other. Chickadees vary in their response to pishing, etc. If they see you, they tend to stay farther away than do other spp. such as juncos, warblers, kinglets, etc. A common occurrence is to have them fly back + forth outside of gunshot range in the tops of large trees while scolding. They respond to Pygmy owl imitations interspersed w/ pishing or to a whistled imitation of their song. This varies w/ time of day and, of course, w/ individual. W slope Whaleback, 8½ mi. N + 2 mi. E. Mt. Shasta, 2050 m., Siskiyou Co., Calif. [T. 43N, R. 3W, SW¼ sec. 26] 4 July Chickadees also very common here (only ca. 3 mi from last locality). Song same as last locality. Bob + I separately ran into the same chickadee in the chaparral several hundred m. from the nearest live trees. Lots of dead snags around.
