O. P. PEARSON 1949 6 Spent the night at Trinidad looking for bats. Saw none in the old store at the crossroads at 9:30 p.m. but some flying in attic of the old Holy Trinity church at various times between 9 and 11. Because of great numbers of 1x12" roof supports and several holes in the roof, shooting and setting were difficult. No specimens. Checked buildings again 5:30-6:00 a.m. but saw no bats. Aug. 19 Looked under north end of Wood River Bridge again and found 5 Epterenius at 6:30. Several other nicely timbered bridges had nothing. Trapline along stream in sparse older woods north of Big Jagoon Bridge had 2 Peromyscus maniculatus, 2 Zapusia, [illegible] 1 Sorex trowbridgii, and 1 Sorex terdini. 46 traps in short grass in marsh again caught nothing. No marmots or cows either. Left before lunch for Orick, thence southeast up to the bold tops or "prairies". Now camped at French Camp, 3100 ft., near one of the prairies and amid Douglas fir plus some incense cedar. Put out 50 museum specials along trickle in meadow, through clear-floor fir woods, and in broken clearing. While setting saw rabbit droppings, gopher droppings, long straight [illegible] mole tunnels, deer droppings, lead chipmunks, and saw 1 tree-mouse nest: Saw one bat flying high and fairly straight east at early dusk, too large for Myotus californicus. Others in camp saw a few others. Traps started snapping at bat-flying time and I took 6 Peromyscus out of my first ten traps before 9:30 p.m. One trap went off about 7:45 followed by a few agonized squeaks audible 75 yards away. Probably A. fuscovacca.
