Orr 1932 3mi. W Payette L., 5400ft, Adams Co., Idaho. July 4, 1932 A Hermit Thrush was heard singing at 6:30 p.m. Placed out 41 mouse and 4 rat traps along the grassy land by the creek and among the firs. At 9:15 p.m. two Hermed Owls were heard nearby. One gave a low "whoo - whoo - uh-who" and the other would immediately reply or break in on the call of the other with a much higher pitched faster "uh-uh-uh-who - who". This was done a number of times until they seemed to fade away in the distance. July 5, 1932 The 41 mouse traps contained 1 Gapes (captured in a small path in grass next to crk.), 4 Microtus mordax (taken along logs & beneath alders in grass land near creek), and 4 Cootanys (2 jew.). The Red-backed mice as noted the morning before seem capable of existing in several habitats, one being grassy land along the creek and 25 feet from firs, the other being the dense fir thickets were the ground is barren of vegetation. Shot a ? Townsend Warbler near the fir thicket where the Cootanys were taken, also in same thicket & solsta or Audubon Warbler. Back at camp at 7:45 a.m. I shot a Red Squirrel (S. hudsonicus) as it was running across a log in the Lodge Pole Pine area. A Red-tailed Hawk was seen during the morning. This evening I shot a Red Squirrel in some firs. Placed out 55 mouse traps in the canyon to the west over the ridge. Traps placed in among the firs and in dampgrass and mussey banks along a little stream. Collected another Bufo cuton
