Downward tail-pumping behavior is shown.
觀察細節
Great find, Kyle. And thank you for relocating it today, Andrew. Now some other species has the chance to become my official Multnomah County nemesis bird. ... The two videos here show the diagnostic downward tail-pumping behavior (rather than the quick up-flicks or up-&-down flicks of most other Empid species). The first photo shows the tail in the "up" position. The second photo shows the tail in the "down position". The bird was giving "whit" calls from time to time, and on one single occasion I heard a single song bout: "chi-bit".
