It is that time of the year again and animals are beginning to mate. The grouse is no exception and the males have begun their unique way of attracting a female. The male Ruffed Grouse will sit on a low log, stump, or rock and create a deep, thumping sound that starts slowly and builds to a blurred crescendo as the bird rapidly rotates his wings back and forth. This drumming sequence can last 8–10 seconds, with the wings beating to 50 times. The best time to hear drumming is just before and after sunrise, although they can be heard other times also.
