P. PEARSON 1949 63 June left at Caves Campground along Hot Creek. Several small bats flew early dusk last night. This morning a dipper was feeding its young along the stream only 15 feet from our sleeping bags. A single parent was attending a single young, which appeared as large as the parent. The young could fly, swim, and feed in shallow water. It kept up a high squeaking accompanied by bobbing motion. The parent did most of her feeding along the edges of the creek, but occasionally dove out in the middle; a little later it developed that this parent (or another) was feeding two young. Looked into the 2 Ice Cave and Parrelh Cave and the single chamber cave 1.6 mi. W. of Subway. No bats in any of them* but considerable ice in both Ice Cave and some in Parrell Cave. Drove to Cassel after lunch, looking in barns on the way etc. Only bat seen (and collected) was in the attic of the big house at Cassel (a * Corynorhinus). It was awake enough to fly. Camped at the Cassel Creamery. Several night hunters hunting over the lake at Snake and many bats—sometimes 2 dozen right at once. Started night hunting about 9 p.m. and did 4 collections in the creamery and in the big house. Many Myotis young on each trip, especially in the upstairs hallway * of the big house and the refrigerator room of the creamery. As many as 25 in the latter at one time. Stored all in butter tins and socks overnight.
