Observation details

When I first spotted it at a distance it struck me as being rather small, such as a Bell's Vireo. Upon getting closer views it was clearly an empidonax, often with an upward tail flick, and acting typical for a flycatcher. It had a shortish bill, with an extensively yellowish lower mandible. The primary projection was rather short, and there was a thin nearly concentric eye ring. It was mostly white underneath with some yellowish near upper flanks/breast. Greenish/olive cast on the back. It did seem to be mostly quiet, certainly without singing. I perhaps heard one or two "pip" like calls, but not heard all that well. It was working the north edge of the riparian strip. I first had it at GPS 34.023482, -117.188660, and watched it move east where I lost it after about 100 yards. We eventually did relocate it, and intermittely saw it ranging as far east as GPS 34.022491, -117.186718. Below is a map screenshot. The yellow is the general range of where the bird favored, and the red is the actual location where I saw it. https://photos.app.goo.gl/fAAxzphnQNfg3BFX6 At first I thought this was a candidate for a Least. After helpful input from Jim Pike and Peter Pyle, they both agree that it is a Dusky Flycatcher.
