Beautiful New Visitor

[Ken Westlund]

I'm a new member of COBirds and this is my first post.  I live in SW Denver (Marston Meadows) and have had a beautiful new visitor to my back yard in the past several days. Checking my bird books, the closest thing I can find to match is a female Peregrine Falcon.  It is about the same size, 16-17 inches, has a long tail, blue back and crown.  The only reason I have doubts that it is a Peregrine Falcon is that it does not have sideburns. If female Peregrine Falcons do not have sideburns, then I am pretty certain that's what my new visitor is.  I got a great picture of her and wish I could attach it.
