Last month this bird visiting different sites in U.K. before reaching North coast of France.
Apparently his name is Bird C 'sterna 2' and has been caught in the Sandwich Tern colony of Banc d'Arguin (Gironde, France) on 3 July 2003.
Ringed as followed: metal ring (FT67249) and 3 plastic rings—one white on the right tarsus, and green above yellow on the left tarsus (J Gernigon). source; birdguides.
This adult male was on a huge beach among the Sandwich Tern group who was relatively shy. Them safety distance was around 80m at least—not good for pictures. Fortunately, late in the evening the hit disappear and I was able to provide this digiscopy.
