final sketch made from field sketch and notes on location at Yorba Regional Park.
觀察細節
See sketch and accompanying notes. Vocalization: Flight note soft zeet. Other calls soft, high pitched whistles, and a weak continuous high pitched whistle reminiscent of a Pacific Slope Flycatcher and more repetitious. While I observed the bird, over about an hour, the bird vocalized when it was in the trees, but not while on the ground. Also I noted that the bird pumped its tail as if it was on a hinge, i.e., pumps its tail down, but does not move the rear portion of the body as does the American Pipit.
