1st winter feeding primarily in the isolated and flowering Toyon tree just north of the Miwok Trailhead, north east of the main lagoon/Shed T1111. Superficially like a Orange-crowned Warbler, but a slightly lighter brighter green, two slight pale wing bars and light cream under-tail coverts. Moved off with a mixed flock of Bushtits/warblers working east up Miwok Trail. Spent about 15 minutes trying to get good views of this bird which eventually came but were very brief! Very poor and cropped photo below.
