June 8, 1935 between camp and Mt. Harrison. I spent the morning in camp. Heard and saw the usual birds around camp. Chipping Sparrows is the most evident bird. Its song is frequently heard. Green Tailed Towhees are continually singing from the hot, Artemisia covered canyon bottom near camp. The full song of the Ruby Crowned Kinglet is often heard. Grosbeaks and Robins sing their similar songs from the wooded slopes above camp, and occasionally a Western Tanager adds to this confusing mixture. Warbling Vireo, Mountain Chickadee, Red Breasted Nuthatch, Junco, and House Wren songs are occasionally heard in the distance. Three Rosy Finches flew over, headed toward Mount Harrison, and uttering the common English Sparrow-like call. The call of the unknown, but suspected to be Hammond Flycatcher, is continually heard. The birds are numerous but very inconspicuous. Aldrich returned empty handed, not even having seen a Marmot all morning. After lunch I started toward the ridge, planning to search for Marmots down the ridge, southward from where we had been hunting. Soon after leaving camp I flushed a Sage Hen from an Artemisia covered hillside, and it flew into a grove of Firs nearby. So far I have noticed that every Sage Hen we have flushed up here have flown from Artemisia into trees. A short time later I saw both Sage Thrashers and Sage Sparrows on the slopes approaching the ridge. Brewer Sparrows were also singing on the slopes of the ridge.
