Eli Kedstrom Buffo (lonera) ehaul June 13 Deep Springs Valley, 5000 ft, 4 mi. SW Deep Springs P.O., Inyo Co., Calif. Sedges are tall here to 3-4', rocky soil very black. Cattle have trampled adjacent area heavily so the grass is clumped and matted, left only up to your knees many places. 3:45 p.m. Draw bridge found single adult ehaul. We withdrew a hundred yards or so waiting for dusk and the chance to tape record under-tumbled sounds. No calls but store of blackbirds late afternoon. Recording begun 7:15 p.m. A few Buffo notes were mixed in with the bird calls and a couple of spade-foot moles. Call is B. lonera helophilus like but slightly higher pitched - up to 3-4 notes in a second time almost uniformly spaced. No real Buffo chorus heard. Adults and tadpoles not easily collected. Method for getting adults was to walk along parting the sedges and watching for movement. The dark body against the black soil is hard to spot, and the light vertebral stripe was highly disruptive. Was a decrease of activity as darkness set in with a dozen Texas (probably) night-herons catching flying insects, blackbird, and amphibia calls. Air temp 15.8 C. At 9 p.m.: about 14 adult Buffo collected (were - to 25 seen but 10 left there) along with Buffo and Scapherjina tadpoles.
