song in display flight from a bird over high quality tallgrass prairie. During the prolonged display flight the bird was fluttering high (at the limit of my sight, maybe 70m) above the prairie. When it would sing it would glide, then after singing it would flutter and move slightly before singing again. The whole display lasted about 15-20 minutes before it would plummet to the ground for a short rest and begin displaying again.
