Sharp-tailed Grouse in Colorado

We spent a week in Colorado where we were fortunate to see this species displaying on a lek near Hayden. There were about 25 birds at dawn
and the displays and noises were amazing. Even more amazing is that every few minutes the entire group would simultaneously stop motionless for about 30 seconds before starting up again. It was as though time stopped for them. The synchronization of the stopping and starting was like nothing I'd ever seen before.
