Looks like Beau is back in West Winnipeg but I only had binocs with me so while it looked like him, I only got very brief glimpses of what I think was a red leg band on his right leg ... Dennis and I will try to get a confirmation on the bird tomorrow if he/she cooperates of course ....
Not a great close shot like Dennis'! It was taken with a small pocket camera zoomed to the max and cropped.
But since I like to ask for photo confirmations 
The bird I saw at the Diner this evening has a head that looks darker than Jules' and looked smaller overall but both Jules and Beau are larger birds, not like our Radisson offspring who are smaller overall. The black on "his" head looked like more than any of our other birds in town at the moment, which is Beau's distinctive feature at least to me since most of our pre-Princess birds had very full black caps.
As for the red band, I just think I saw red. Now whether it was full red or black over red, I can't say for sure. The only other birds we know of in town with red on its band is Jolicoeur and this bird did not look like her ... nor Alice who has stayed/passed through town in previous years. Sandy from Fargo who has visited in the spring in past years also has a black over red band but this bird seemed male sized.
While I was watching, bird's head was on a constant swivel looking for his/her mate. Then a crow came by and protested the peregrine's presence and that set him off and he took off after the crow like it was another peregrine. Seemed like territorial defense to me, another indication that this bird is one of the WW resident pair. After lots of aerial acrobatics and yelling, the crow went one way and the peregrine went north to do a few lazy circles before returning to the Diner to sit in the NE corner in the sun. About a 1/2 hour later, he took off to the north very fast - I suspect to go kill something. And that was the last I saw of him ...
