Sorry for the delayed response Andy, I`ve been off line for a couple of days.
Thanks for the compliment, the Terns were taken at the shorter end of the zoom as they were mobbing people & the Puffin was taken at full zoom as it approached me at an oblique angle. I find with the Sport mode that even if you get the tracking focus spot on the bird & hold the shutter down until you hit the buffer you`ll still get several shot that are out of focus, but usually one or two that are good enough to keep. Here`s a couple more.

I'm liking the look of those additional results! Can I push you for confirmation that you are using Sport mode with Tracking focus. I don't appear to have the option of Tracking focus in Sport mode :C
