R.E. Johnson 1967 31 Journal June 18 Warren Pk, Warner Mtns., Modoc Co., California Robin, [illegible] Mth Bluebird, & Clarke Nutcracker also present. No birds were seen on the open ridgetops + "meadow" on the west slope. All were in trees below ridge or on rock outcrops. Walked south to point 9053ft (nw of Dusenbery) & returned. Cliffs to east of ridge appear adequate for rosy Finch nesting (ie cliffs + snow) + have abundant melt-out areas below For feeding, However the elevation is probably too low. Conclusion regarding rosy finches: None found on Squaw Pk, Warren Pk, ridge South of Warren to pt. of elevation 9053 Ft. Dusenbery Pk looks no better (is lower) and Eagle Pk appears to have less cliff area. Presence of trees & rock wrens on top of peaks may be indicator that climate is wrong for rosy finches. Dusky Flycatcher sings "du-hic" song From top of White-bark Pine Tree near Cottonwood Lake at 7:15 PM. Another sings "du-hic" song From tree top near camp. It would sometimes sing "du - du - du - du - du-hic" and once it sang "hic" several times in sequence. A White-crowned Sparrow was heard near camp at 8:45 PM. Bats flying around tent at 9:00PM. Still fairly light, but too bed anyway.
