Ground display from the same bird as in ML107535261, given about 15 minutes after playback. During the display the bird was perched on fairly dry tundra, and would lift both wings part-way up. It would then flick the wings higher rapidly in time to the clicking notes in the display. This particular display was heard much less often than the flight display, and appeared to be mostly be given at long intervals.
