A late Yellow-rumped (Audubon's) Warbler in female-like plumage photographed by Curtis A. Marantz on 27 May 2023 at the Lake Tamarisk community, Desert Center, Riverside County, California.
觀察細節
I saw a well-marked bird in female-like plumage in the heavily flowering Desert Ironwood tree along the northern edge of the park west of Parkview Drive. This bird was foraging actively, which madwe it a little difficult to photograph, but I saw it quite well. I also heard it give the typical, "flat" chip-calls of an "Audubon's" Warbler rather than the drier call of a "Myrtle" Warbler. This was a relatively large warbler with a slim bill that was quite short, a rounded crown on a head of unremarkable size a relatively short neck, a plump body, and a tail that was relatively long for a warbler, slightly flared distally, and weakly notched at the tip. The plumage was a medium to somewhat darker gray on the head and back, but also with a bright yellow rump that contrasted with a dark tail. The face pattern was characterized by narrow crescents of white both above and below the eyes, but no other obvious markings. The throat was entirely a bright, lemon-yellow from the chIn to its junction with the upper breast, but it did not flare at the corners like that of a Myrtle Warbler. The upper breast and I think also the sides to some degree were grayish, but I cannot seem to recall if this bird had yellow patches on the foreflanks. The remaining underparts were a dingy, whitish color and with a few fine, dark streaks on the flanks. The underside of the tail had elongate white spots on either side, but they were framed by a narrow border of black. The wings did not contrast strongly with the back, but they were generally dark, but with narrow, yet well-defined, tips of white to the greater and median coverts and light edges to at least the greater, which produced two, narrow wingbars and a finely striped pattern between them. The remiges were likewise dark-centered, and they too were narrowly edged with light gray to produce a finely striped pattern to the rear part of the closed wing. I thought the bill, eyes, and legs were all dark, but I failed to determinne the colors of each more precisely.
