Observation details

Heard calling from the bushes behind the Brush Rabbit Straight sign at 37.6159800, -121.2062335. I got the briefest of glimpses of a small yellow warbler moving around in there, but not long enough to pick up any other field marks. Attaching a couple of sound recordings. It sounds like a good fit for a Wilson's to my ears, and, FWIW, Merlin consistently ID:ed the call as a Wilson's. But other opinions are more than welcome -- this species is obviously not expected this time of year (...though I see now that it was reported last winter as well).
