觀察細節
This bird has relatively well-defined/distinct streaking down the back with a thin moustachial which does not contrast with the rest of the head, supporting A. nevadensis opposed to A. b. canescens. These photos where shown to Chris McCreedy, who does research on sage sparrows, and he said "When you start getting out into creosote bajadas and away from thicker scrub Sagebrush become much more likely relative to Bell's. It is not diagnostic but habitat predicts them fairly well in large portions of the Mojave and Sonoran Desert. I find the habitat associations work least well when you are in Bell's nesting habitats (e.g., around the eastern Sierra in Kern and Inyo) or for not entirely understood reasons near aridland agricultural situations in Yuma). Your location is suggestive of Sagebrush and some of the veg you photographed them in is suggestive of Sagebrush. The second bird looks like an easy Sagebrush." The photos I added are of that second bird.
