O. P. PEARSON 1949 Bitter rootings on a bolt under the little bridge at our Coon Creek Camp. A large [illegible] but disorderly bed of moss on one of the piers may have been remains of a nest. Aug. 30 About 100 traps out, 20 of them new sets, but only 2 spring - yielding 1 Peromyscus. While hunting chipmunks about 10 a.m. saw another Vigry owl perched at top of big madrone. missed. Went batting to Patterson reach in afternoon. Mr. Patterson told of 3 bats roosting in a rock over his bed last night. Could not find them. Set 60 Museum specials baited with walnuts + oatmeal west of the Trinity River on the flats north of the bridge. Most of the traps along a small stream bed, dry in most places, choked for the most part with blackberry willow, sedge, junco, [illegible] + water cress. Saw Meriones? droppings in several places. Blackberries ripe and abundant. One very orange Myotis calif appeared in our camp grove at 6:15. Collected him by the coruscation method. On about half of the dozen occasions when we have shot at bats under the leafy canopy of the maple grove at camp here the bat has been obviously confused and has either fled or spiralled slowly upward. True for both M. calif, and M. volans. Looked specimens for return tomorrow.
