Hoffmeister 1942 Itinerary 1/4 mi. N & 2 1/2 mi. E Benton Station, 6900ft., Mono Co., Calif. jays to return. However, during the next 35 to 40 minutes, no Calif. Jays appeared and I am sure the adults and remaining young continued to move on south over the ridge. I noted a Hummingbird (kind not ascertained) chasing a Mountain Chickadee. Whenever the Mt. Chickadee attempted to alight, the Hummer would chase it away, the Chickadee took refuge finally several hundred feet away in a piñon. I collected the chickadee. Earlier in the a.m. I flushed a covey of quail from a piñon where they roosted during the night. I did not see them but heard them and am quite sure they where California Quail. June 17 Set out 35 mouse traps in the vicinity of the place I caught the Dipodomys the night before. Caught 4 Peromyscus maniculatus, 1 Peromyscus ttruei, 1 Eutamias (in mouse trap), and 3 Perognathus parvus. Caught 1 Peromyscus crinitus and 3 P. maniculatus around the grub-boxes in camp. Around these same boxes 2 night previous I caught a Peromyscus truei. One gopher set caught nothing. During the day I saw 4 Eutamias along a rocky wash bordered by steep rocky sides to the north and an Artemisia flat to the south. About 5 p.m. I got a glimpse of what I thought was a Citellus lateralis. I set out 3 Schuyler traps
