Field Marks and
Identifying Characteristics:
A small bird flushed from the large pomegranate bush behind the marble Lytle Ranch sign and landed in the large ash tree. I noticed it because of it s rapid tik, tik , tik, tik call note. I had only a brief glimpse before it moved up into the large ash tree and then flew into the cottonwoods before I lost it. I suspected it was a female Black-throated Blue Warbler so I searched the area for another 30 minutes or so eventually relocating it working low in the underbrush near the pomegranate bush where it was originally feeding.

Upperparts rich olive green from head to tail, slightly darker olive wings with prominent white check midway along edge at the base of the primaries. Face dark olive green with a thin pale yellowish supercilium stripe stretching above eye, and a white arc below eye. Upperside of tail dark with a bluish green sheen / edging. Throat, breast, belly, sides, flanks, and under tail coverts buffy whiteish. Eye dark, and legs pale pinkish.
