I heard back from Pete Potts the other day that the colour-ringed Sanderling I saw at Southsea Castle on 6th December was indeed on of his. It would appear that any bird ringed with a blue flag will have been ringed in the UK and by Farlington Ringing Group, Pete being the lead ringer. This bird was originally ringed on 18th September 2013, at Eastoke, Hayling Island, Hampshire, so this sighting was only about 10km west of its original capture site. It has been sighted 12 time since it capture, with all of the sightings being on Hayling Island, except two, which were mine and a sighting from Ryde Sands on the Isle of Wight on 17th February 2014.

Out of interest I recently saw that a different colour-ringed bird was recorded at Southsea Castle on 29th November 2014. This bird was originally ringed on 3rd October 2011, and has been recorded every winter since on Hayling Island, with occasional visits to other locations including Ryde Sands, on the Isle of Wight and Gilkicker Point, Gosport.
