Teesmouth Bird Club

This was the response from one of my pictures of a Sanderling from Marske beach.

It was colour-ringed with a Green flag on the right Tibia (G2) and Yellow,White on the left Tarsus, Green,Red on the right Tarsus.

I have observed two other Sanderlings marked G1GWWY and G2YGYW on Marske/Redcar Beach.
