In the spring, male Ruffed Grouse perch on fallen logs and make a low-pitched drumming sound by opening and closing their wings in rapid succession. The thumping starts slow but quickly gains in speed, and the rapidly beating wings turn into a complete blur when the drumroll reaches its peak.

One might think the thumps are produced by the beating of the wings against the chest, but in actuality the thumps are little sonic booms created as air suddenly fills a vacuum made when the wings are thrust outward from the breast.

  • Holyy cow. i turned the speakers so loud then all the sudden, "VIRUS DATA BASE HAS BEEN UPDATED" scare the crap outta me.

  • Awesome video . . . thanks for sharing with us. I take it this is a homebrew video camcorder setup. I am interested in what camcorder you used for this footage. Best quality that I have seen. Would like to build one with same camera. Please respond with camcorder info. Thanks

  • My boys love this video!

  • I heard this sound while camping. The noise was so low it was almost inaudible. The sound seemed to be coming from the ground and I thought it was some type of seismic event. I never would have suspected it was bird! Awesome footage! and thanks for solving this mystery

  • i hate grouse when hunting they fly like 9000mph

  • Absolutely amazing footage!

  • I've been trying to figure out what the brown bird that ran next to be on a logging road hike last spring was, making a deep "oooooooo ooooooooooo" sound. This answers that, thanks :)

  • Oh my god! What kind of camcorder opr camera did you use for these awesome videos? Congratulations, there's lot of work with a video like this.
