song and mechanical wing noises from a male bird in a flight display over wet tundra. During the display the bird flew low (about 0.5m) off the ground in a horizontal flight with it's chest inflated and drooping down while giving the low hooting song and the weird mechanical wing noises, before suddenly undulating three or four times up as high as 3m and then swinging back around to where it started. After the horizontal portion of the display the rest of the display was completely silent.
