Steve describes how he concluded that 'hybrid' seems the best solution for this intriguing bird:
"The gray underparts, gray face, dull supercilium and eyering, and nape streaking all favor Brewer's Sparrow.  The bill size, white throat, strong malar and moustachial, and bit of buff on flanks fits Clay-colored Sparrow.  This combiantion doesn't fit with Timberline Brewer's Sparrow, which is somewhat intermediate between typical Brewer's and Clay-colored Sparrow, leaving Clay-colored Sparrow x Brewer's Sparrow as the best solution."
