new world quail sp.

Looked like a Gambel's Quail pair. Needed to get closer to make sure lower chest was all white and unmarked with any streaking as it appeared from a distance. Crown appeared bright chestnut instead of brown which could have been due to how it was lit by the angle of the sun's light.

included both heard and one of those seen on top of a rock at the ridge line below the spring.

most of which were Lutescens and one of which was a male Tennessee Warbler look alike except for yellow undertail covetrs. The Tennessee look-alike had gray cap, white sides of face, white supercilium, dark eye-line, white throat, white chest, and white belly. This was a case of looking at the undertail coverts to eliminate Tennessee in what was an otherwise beautiful male Tennessee Warbler! Coming to the water on the ground next to the water trough outside and below the main spring cattle exclosure fence.
