Observation details
In the field, I heard a repeated vocalization several (4? 5?) times that strongly reminded me of Rock Wren. I was able to record the last iteration before the bird fell silent. I recorded for another minute and waited for several minutes afterwards, but did not hear anything more. No visual. When I heard this, I was standing near the dry rocky draw which drains into the stream from the north. I was ca 5-10 meters north of a Chokecherry thicket mixed with Skunkbush Sumac (Rhus trilobata; south of it were alders along the creek. The call seemed to be coming from east or northeast of me. The habitat in this area is short native grassland (spp. include Bouteloua gracilis, Liatris punctata, Opuntia polyacantha) mixed with introduced Cheatgrass (Bromus tectorum). UPDATE, October 2020: after thinking for several years that this call could be nothing except for Rock Wren, I heard a NSHR make a similar call this fall. Upon careful study of this record and comparison with calls of shrikes and ROWR, I conclude that this can not be a ROWR. The wren's calls tend to be a bit higher-pitched with a wider frequency and a rapid trilled quality. Although this bird was not seen, it is fairly safely within the expected season for NSHR and outside the season for LOSH (i.e. NSHR has been documented in early October on this site, and LOSH has never been documented later than September in Lewis and Clark County).
