Thanks gents.
Bird number two was the icing on the cake that I wasn't expecting.
The seated gent didn't know the bird was behind his shoulder. He didn't realise I was there, either, until after I had taken this and when I was lining up for another shot that might catch any more birds that might be incoming. No more birds were incoming, but all through it, he didn't know he was part of the scene I was photographing.
