Mystery Egg

Dear Sir:

I am not a knowledgeable birder, but am hoping to identify the bird we saw nesting high on a canyon ledge near Grand Gulch, UT on 4/18/08. While exploring some remote Anasazi ruins we realized that there were 2 agitated birds, swooping down like they were dive bombing us. We took a couple pictures and left, since we did not want to disturb the nest. It is the first time I've seen a nest on these ledges. Unfortunately they moved so fast I could not see much detail or photograph, but am pretty sure they were not falcons. Looks like some kind of gull or turn. The rangers could not identify using their book on Utah birds. Were light colored, gray or white with dark accents on tips (again, I could not make out much detail). I'm not reporting this an a rare siting, just wondering if you can point me to some resource to identify. In searching the internet I am not finding likely birds that have this purple egg (about the size of a small hen's egg). Franklin's Gull? Forster's Turn? Common Turn (which I read sometimes have odd colored eggs)? There is a lot of water in the canyon, so maybe shore birds might go there. One time we saw Mallard Ducks in Grand Gulch, which made us feel right at home, since they are so common in Seattle.

Thanks

Packrat droppings and mystery egg--I think this photo has very accurate color.
