Tree Swallow about to recieve a stinging surprise!!

While attempting to photograph Tree Swallows in flight at Armleder Park yesterday when i noticed that there was a bee chasing them! (they are hard enough to capture on their own but add a bee chasing them into the equation and it was, well, almost impossible lol) So I was going through the images and to my surprise, was lucky enough to capture this swallow that was unknowingly a split second away from a rather big surprise of his own!! (may have to zoom in to see it!)
