- Not Used
**Quite surprised to detect this species - first detection so far this year here, and seems quite late. 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. Given the lack of a visual or any further vocalizations, I decided that I would have to leave this one unidentified and did not even take notes in the field (these notes are based on memory the day after, 10 Oct). However, upon checking my recording, I did indeed capture one of the vocalizations, and it strongly reminds me of ROWR. I don't know of any other species that make a similar call. 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 Grama, Liatris punctata, Opuntia polyacantha) mixed with introduced Cheatgrass (Bromus tectorum). As mentioned, there is a minor rocky outcrop visible upon cursory examination at the draw; vegetation there includes Rhus trilobata, Toxicodendron rydbergii, and Phlox sp.
