I saw a single Yellow-Rumped Warbler at Vasona Lake County Park this morning, quite an early arrival! It seems to be a FOS for the park, and maybe one of the first of the fall migration season for the county as well? I saw it in a large tree (what I believe to be a Western Sycamore) a bit past the red bridge on the west side of the lake, near the benches to the south of the boat launch.
Exact coordinates were around 37.24093° N, 121.97022° W. I've attached the best photo I was able to get that shows a good amount of identifying features.
