Yeah, we have a prairie falcon pair every year that nests somewhere between Egg, Teapot Dome, and Chaos Crag. I've seen them at Chaos Crag, Teapot Dome, and Ball Pinnacle so far this year, but as they focus more on a specific site for nesting, I'll let you know. That falcon territory is small enough - and close enough to trails - that I try to give the birds a bit more space. Remind me as summer approaches and we'll see where the birds are at in their nesting schedule.
