Grouse are just about non-existent these days, but some are still around. Now is the time they begin their courtship drumming and a good time to get a feel how many there are. if you are out in the woods and hear their drumming and are so inclined, post it in this thread. If your unfamiliar with the drumming sound, you can go to the link below and hit the button under the drumming label.
