The origin of the Polish colour-ringed Black-headed Gull

We heard today that Polish colour-ringed Black-headed Gull (blue TJJ7) which was at Pembroke Middle Pond on Saturday was ringed as a nestling at JEZIORO ŁĘGOWSKIE, Wągrowiec (a lake on the western side of Poland) on 20th June. It has moved 1,502km from its natal area. 

There have been records of other ringed BH Gulls from Poland and elsewhere over the years which we hope to add to the online avifauna at sometime in the future. 

Yesterday a merlin was hunting around Frainslake and Freshwater West. Still not very many redwings around here but Annie noted a flock of about 30 in some trees near Little Waddock today.
