觀察細節
Field views were pretty poor. It was feeding mostly along the river (i.e., back) side of a row of Russian olives in poor light. When it finally flew up into the sycamore tree (last 2 photos, below), in better light, I just snapped a couple of last photos rather than view it through binoculars. A moderately bright and almost uniformly yellow warbler with a fairly short tail and straight sharp bill with a thick base. Pink legs. Kind of a plain "blank-faced" head pattern with a slight seemingly-complete eyering but lack of dark eyeline or eye-arcs seen in orange-crowned. Large dark eye stands out against otherwise plain face, the way id does in Yellow Warbler. Wings a bit darker than body with boldly-contrasting tertial edges. The undertail was mostly or fully yellow including all the way down the center of the folded undertail. Silent. Loosely associating with a group of golden-crowned kinglets and a couple of YRWA (though a YRWA seemed to chase it off at one point. Face pattern, undertail pattern/color, white tertial edges, and bill structure rule out the alternatives (of which OCWA and WIWA seem like the only options).
