Smiley and Joli are still playing house at the Radisson - she had breakfast on the ledge about 0930h but don't know if Smiley caught it for her, I suspect he might have because I spotted him after she'd left with the head which is the best part of the bird for the peregrines so I can't imagine she would have left it for him if she'd had it.
In any case, they tend to hang out on the nestledge side of the building though they will drop by the nestbox but it appears not for as long which is interesting since the nestbox was their preferred location in the spring and was possibly part of the reason that Princess chose the ledge in the end.
I don't think Joli is going to "leave" Cowboy if he returns next spring, I suspect that she is like Ivy, a bit of a "flirt" (to put it mildly) and her default is the "date" whoever is around. Joli "dated" Ivy, then Smiley then Cowboy. Ivy dated Jules, then Joli then Princess. Next spring may be very interesting ...
