Common Scoter still and a Returnee.

 The female Common Scoter was again present for its third day.(24/11)
 It had moved to a more central area of the reservoir and was still busy feeding.
 I first recorded this Black-headed Gull on 16/12/2014. I was able to read its ring using my telescope. The code was 5426233, HELGOLAND, GERMANA.
Today I was reading the ring of this adult Black-headed Gull and realised that it was the same bird. Perhaps it returned to Helgoland to breed this summer and has returned to Thornton for the winter. I will pass on this record to the German ringing scheme. By being able to identify an individual it is possible to discover the movements of bird species, and better understand their conservation needs.
