We went back and saw a group of birdwatchers way along the bank at Creekmouth. I decided to run as I thought the bird was drifting down river away from us. I puffed up to see the bird through someone's scope and had about 10 seconds before it flew off!! David didn't run and missed it. However, after 25 or 30 mins it showed up again and we got good though distant views. The tide was right out so the birds were quite a long way from the bank. Light also not good as very overcast. The poor thing was constantly chased by black-headed gulls so it was on the wing most of the time. Here are a couple of photos showing the main ID features: black spot behind the eye, relatively clean underwing, black bill and pink legs.

Went back on Sunday to try and get a better shot. I did get a little closer. Here three of the main ID features are shown better: spot behind the eye, black bill and pink legs.
