Observation details

Male found by John Green in a strip of willows and mulefat along the Santa Ana River trail between the 10 and 215 freeways. This was a fairly active warbler, generally staying low among the mulefat as it foraged methodically, gleaning insects from the leaves and branches, but occasionally venturing higher into the willow. It had a habit of pumping its tail downward, much like a Palm Warbler, although somewhat less regularly or consistently than that species does. The crown and upper parts were olive, with faint brown (rufous?) streaks on the back. The under parts were bright yellow, with black streaks on the sides of the breast and flanks. The face was yellow as well, with a bold black eyeline and black semicircle below the eye, creating a bold pattern of a yellow supercilium and a broad yellow arc immediately below the eye. The tail was generally blackish, but with extensive white in the outer tail feathers. The bird called a few times during our observation, giving a rather emphatic "chick".
