觀察細節

Beautiful hatch-year warbler found around 11:15am with a large mixed flock in the crown of the large valley oaks near the FA2 gate. It was seen briefly (but identifiable) and photographed poorly here before the flock dispersed and we lost it. About an hour later at 12:20pm, we relocated the flock and found the CSWA foraging at eye-level in some willows and cottonwoods. The flock contained ~3 YEWA, 2 BTYW, 2 WAVI, and a CAVI, and was last seen around these coordinates: (38.5140635, -122.0745866). This was a very crisp warbler, plain white below brightest near the vent and undertail coverts with a slightly grayer wash to the upper breast and face. It had a circular while eyeing and a spectacular lime-green wash to the top of the head and back, along with two bright yellow wingbars. The tail was relatively short and especially thin, which coupled with the plain underparts made it stick out of the flock from below. Lifer for Julian and Ethan! Photos to be added.
