Sussex Caspian Gull recoveries

The Museum and Institute of Zoology of the Polish Academy of Sciences have kindly been in touch to say that a couple of colour-ringed Caspian Gulls that we have encountered in Sussex have been recorded subsequent to leaving Sussex as follows:

First ringed at a Caspian Gull breeding colony in Poland as a 3CY+ male on the 19/4/2011 it was seen in a river valley at Maasbracht in the Netherlands on three dates in August 2011. A year later it was seen at the same site on 28/8/2012 before moving c.40 miles southwest along the river valley into Belgium where it was seen at Lixhe on the 10/9/2012.

We saw it in the Cuckmere on the 16/12/2012 and it then made its third consecutive August appearance back at Maasbracht in the Netherlands on the 6/8/2013 before being seen back at its original colony in Poland on the 29/6/2014.

Showing such spatial site fidelity has it been 'missed' back in the Cuckmere in the last two Decembers, and will it be seen again there in future years...
