The throat looks white on my monitor. Face pattern is wrong for
Philadelphia which has a triangular black lore stripe, widest at the eye.
It looks like a Warbling Vireo to me.

Coming from the midwest, that questionable vireo (esp image #ML117683161)
looks good for a Philadelphia. The yellow is uniform
from the chin through to the belly while Warbling (in the midwest at least)
have a whitish throat. The delicate head and bill also contribute to it
being a Phillie. Some of the images tagged for Vireo Sp (e.g. ML117683241)
look to me to be Warbling. Do "western" Warbling have yellow throats in
Grayslake, IL (I miss California!)

I had several vireos yesterday at Fort Mason, that I initially assumed
were all Warbling Vireos (other than the Hutton's), but at least one
doesn't look quite right for a Warbling. They are on my eBird checklist at
<https://ebird.org/view/checklist/S48950384> Today I couldn't find any
vireos at all, but the CLAY COLORED SPARROW continued in the garden, there
was a OLIVE-SIDED FLYCATCHER in the Battery (which also had at least two
BLACK-THROATED GRAY WARBLERS, a YELLOW WARBLER, several TOWNSEND'S WARBLERS
and many YELLOW-RUMPED WARBLERS). A NASHVILLE WARBLER and a SPOTTED TOWHEE
showed up in the garden, and five NORTHERN PINTAILS flew by heading west
over the Bay.
