Female-type foraging in peppers, alders, maybe sycamores, and some exotic trees near the parking lot by the beach club. It looked like a Townsend’s Warbler at first glance, but I quickly noticed how pale it was. Instead of bright yellow, it was ghostly whitish. This bird shows a similar facial pattern to TOWA - yellow eyebrow mark and mirroring stripe underneath the dark eye patch. However, the posterior portions of these two lines fade from lemon-yellow to white. And while the dark face patch does not connect broadly to the nape, the yellow-white lines bordering it both above and below still do not converge towards the back of the face, as would be the case in Townsend's. Also note the faint upside-down pale crescent underneath the eye, giving it the inverse "eyebag" appearance of a TOWA, not the completely masked appearance of BTYW. In the 1st, 4th, 5th, and 6th, photos, there is a noticeable "cape" of gray on the nape and upper back (BTYW), in addition to the streaked olive back (TOWA). While the lighting is altered in the last three images, some of the intermediate marks (upside-down eye crescent, pattern of stripes above and below, etc.) are still visible. This may be a bit more of an anecdotal mark, but the last photo seems to show a bill larger and blunter-tipped than TOWA. Note: some people have said the photos taken were of different birds. Just to clarify, all of the attached photos show the same bird. It was one of the only passerines foraging in the area, the others being a kinglet, YRWA, and an adult male Townsend's, none of which this bird associated with at any point during my observation.
