NOTES: (Background Sounds: traffic, train; Species Sound: constant; Breeding Status: territorial, territorial paired, breeding?; General Climate: arid; Cover Density: open; Strata in Habitat: song perch; Filtering: yes - Nagra filter on step 2) Copied at LNS onto AGFA PEM468, then edited by RSL. Male "made the rounds" of its territory over a period of about 1 hour, singing for 10 minutes or so from one fencepost before moving to another or to the top of a sagebrush clump. At least 1 female was within this territory; at one point I flushed both birds from sagebrush as i tried to get closer to the male. This is the same bird that Greg Budney recorded on the fence during this same period of time. Part A: 6:13, Part B: 9:54
