Gannet Central...

...at RSPB Bempton Cliffs. I  rarely even try to get a bird in flight, but there were so many obliging candidates, it seemed rude not to try.  I managed a not quite sharp Albatross too, but that's just a record shot for me. More Gannets in extras as they are so photogenic. I gave up with the converter on the 300mm lens, but used it with much better effect with a 70-200mm. Heavier, but more accurate.
