Very noticeable orange abdomen in flight.
No interactions present.
I've added 2 more photos. I was shooting in bursts so all the others I took were duplicates of the 3 now posted.
My first impression was that the abdomen had quite dark markings. Not sure now...unfortunately the other pics don't add much in the way of a different view.
See what Roger thinks...
