Oyster Catchers Only

I have been trying to photograph this species for some time now, and then on the the 26th of December, I had some success. The weather was fine with plenty of available light that allowed fast shutter speeds.

My camera settings on my Nikon D300 was as follows, aperture f8, exposure compensation for the flight shots was -0.7 and for the others was -0.3 and perhaps should have been -0.7, ISO 500,all that resulted in a shutter speed of 1/2000th of a second.
Location was at Marazion, Cornwall, in and around Chapel Rock.
