In Spring, males occupy individual singing grounds, openings near brushy cover from which they call and perform display flights at dawn and dusk, and if the light levels are high enough on moonlit nights. The male's ground call is a short, buzzy peent. After sounding a series of ground calls, the male takes off and flies from 50 to 100 yards into the air. He descends, zigzagging and banking while singing a liquid, chirping song. This high spiralling flight produces a melodious twittering sound as air rushes through the male's outer primary wing feathers.
