Sadly we didn't quite get one's in flight, the few that were around were intent just on feeding, taken with buddy Jamie D, perhaps we may get some better opportunities later this month or in March.
I would have preferred the BKG to be more diffused and a lot less distracting, but the distance between BKG and subject wasn't huge, plus Jamie was test driving the 500 before weighing up buying the lens or the 600. When close up, this really are, big birds.
Many thanks to those who posted a reply or looked at the previous image.
