観察結果の詳細
Struggled with this ID, as BCGN was more expected at this spot (right at the Warsaw canyon-Cali Gulch confluence), but settled on BGGN after sending photos around for review by a few experts. Black above eye is a long straight line rather than crescent, tail is less graduated than typical BCGN, foraging was very active, no brownish seen in upperparts. Unfortunately, we did not record song, but we studied it and compared it with recordings of both BCGN and BGGN in the field, and this was what made us most confident that it was BGGN at the time, as it appeared to match western BGGN calls spot-on (Bzzzzz - bzz bzzp). Bill length seems more consistent with BGGN, though possibly within range for BCGN.
