This is a body feather as there is a downy tuft at its base. The inner vanes are irridescent. The feather matches in appearance breast feathers of Greater Roadrunner. The habitat is appropriate. Hopefully one will be seen at this location soon.

Description

Slender tree, with one main trunk, around 4 meters tall, growing within and up through the canopy of a mature and large Malosma laurina in lower Johnson's Pasture, Claremont Hills, San Gabriel Mountains foothills. Had to weave my way through a hell of a Malosma thicket to access this thing (see photo # 10) - super well hidden. No true leaves present on the plant, with only phyllodes remaining. The phyllodes are lanceolate, to narrowly elliptical, to oblanceolate in shape, and have a glabrous feel, with few, fragile, dainty, white hairs, mostly nearer the base, not sticky or glandular. Phyllodes with a weak resinous smell. Young inflorescences starting to form in the axils, apparently single-branched, paired, with two emerging at each axil. Coin used for scale is a US quarter dollar (¢25 piece), 24.26 mm, 0.955 inch in diameter.

This plant already observed by Nancy Hamlett (@nvhamlett), I believe with use of a telephoto lens, and this observation was made to provide some closer photography and inspection.

Two individuals of this species were crawling near two mating Lytta auriculata beetles, which repeatedly moved, apparently to avoid them. The red and black insects appeared to attempt to pierce the beetles with their mouth parts. Unfortunately, the photos are not strong enough to see clearly what is happening. I'd welcome hearing any thoughts on it.
