To catch a skimming bird

My main aim on the beach this year was to snap a black skimmer skimming.  I don't think they really feed here, but it was evident some would have a quick skim as they flew in.  Cleaning their bill?
They are fairly cool looking birds anyway so I was happy to snap away in the hope that every so often there would be a chance of that low flying one dipping that  bit lower still. 

The morning light enhanced the experience but for the smaller in frame shots a letterbox crop looked best.

They should look better bigger so click on one of the pics for a larger view.
