Swarm of bees : #5 of the season

This is the fifth swarm we've had in our yard this year.  Number 4 was either just before or just after this one.  Jamie saw it, I didn't. He said it was high up in the trees and by the time he could call me to come out it was already moving on. 

Our friends Tom and BJ need a swarm and if one is withing a retrievable height I'm to call them right away.  Number 5 for the year was too high to retrieve.  

Jamie was the first to notice this swarm.  I really hope it's not any of my bees...but only because that would mean I'd have an unmarked Queen left in my hive and my marked Queen would be on her way to her new palace.
