I thought initially that it was a Common Tern but it turned out to be an Arctic Tern,must be more critical with my ID in future (we won't go there either !!)
I was well pleased with the performance of the tern and drove back up to the first bay where the phalarope had re-appeared and Rob was happily snapping away with his big Canon 500mm.
The bird was picking it's way along the concrete apron and I managed a few shots from the road,with these birds having a reputation for being so tame I thought I'd give it a go legging it over the barrier again and down on to the concrete apron.
The tiny bird was not in the least bothered and both myself and Rob were able to get plenty of good shots,at one time it came within 3' of me and for a lot of the time it was too close to focus !!
