I was surprised to see a Prairie Falcon posing quite nicely for me on a pole along a dirt road I frequently run which is on the east side of Dry Creek Res.
The road is maybe private, it is unclear, but no one seems to mind people walking/running/skiing on it. You could park at the corner of Co Rd 23E and Co Rd 6 and walk north on the road. I saw the bird near where Westhill Dr meets the dirt road.
