觀察細節
Annually, seasonally reliable location. Observed one with some daylight remaining, located by typical 'peent' call. Calls heard from four different directions with two birds concurrently displaying in air, wings whistling on ascent with chirp sounds on descent and birds returning to location from which they took flight. Several silhouettes of the birds seen in air. Sound recording:
