A drumming grouse is a male game bird who, in the spring, stands on a stump, log, or something that gives him a perch as a place to proclaim his territory. He then beats himself on the chest with his wings, very slowly at first but with increasing speed until he sounds like a snare drummer going as fast as he can.
Why would a male do this - why to call a female for breeding of course.
Sometimes you’ll also hear a young males will do this in the fall for practice.
See the link below if you’ve never heard it in the woods (and couldn’t identify it). This will give you a chance to add to your book of what strange things males do.
