Koffmeier 1947 Itinerary June 19 (cont.) 5 mi. E + 1 mi. S Mono Mills, Mono Co., 8300 ft., Calif. on a dead yellow pine log. A golden-mantled ground squirrel was on this same log. I shot 2 Citellus lateralis. These ground squirrels are numerous as much as there are many dead and fallen yellow pine trunks in this forest. I saw 1 litter of 6 young C. lateralis on one such log. Neither I or other members of the party have heard or seen any chickarees. Birds seen or heard in the vicinity of camp include: Steller Jay, Wright's Flycatcher, Violet-green Swallow, Pigmy Nuthatch, White-breasted Nuthatch, Clark Nutcracker, Mountain Chickadee, Sage Thrasher, Cassin Finch, Vesper Sparrow, Cross-bill, Junco. June 20 Set 110 traps along the creek west of camp. This creek is on the average 1 foot wide and 6 inches deep. There are a few willows and aspens growing along it with grass and some marshy areas. Caught 9 Peromyscus maniculatus and 1 Microtus longicaudus. The microtine was caught in a marshy spot beneath an old yellow pine log. Scores of other traps were set in nearly similar situations but caught nothing or only P. maniculatus. Some of the traps were at the water's edge with the hopes of catching Sorex palustris or other shrews. In the thickets, debris, and grass along the creek, there are numerous ticks at this time of year. Mole workings are fairly common along the creek but time did not permit to try to trap them.
