Focus On: Gull-billed tern

Gull-billed Tern (Gelochelidon nilotica) can be found in Arabia most of the year and has bred here since the mid 90's. They are found throughout the world and occasionally find their way to the UK.

The flight shots below were taken with a Canon pre set which I've listed at the bottom of the page (for 7D). They are quite as sharp as they could be but that's more because of my technique which I'm hoping to improve on.
