Colour Ringed Black-headed Gulls

Four colour ringed Black-headed Gulls at Little Marlow GP in five days is not bad.

First of all was "White EA4F" on 19th November.

"White EA4F" was ringed as a nestling on 31st May 2014 at Griend, Holland.  It was first seen at Little Marlow GP in February 2016.  It reappeared in October and November 2016 and after that not again until this week.

Then on 22nd was "Yellow 2PJH" and "Yellow EMJN".   

"Yellow 2PJH" is a bird ringed by the North Thames Ringing Group, so a relatively local bird.  It was ringed in March 2016 as an adult at Pitsea Landfill and subsequently seen at Little Marlow several times between Nov 2016 and Feb 2017.

"Yellow EMJN" was ringed in Zoutleeuw, Belgium, about 420Km distance, on 2nd June 2017 in the nest.  More information on the Belgium ringing scheme can be found on this link.

Finally on 23rd was "Yellow 2KRC" 

"Yellow 2KRC" was ringed by the North Thames Ringing Group at Pitsea Landfill Site 21st March 2015 as an adult.  It was first seen at Little Marlow in January 2016 and also in February and March.  It was then not seen until the following winter when it was seen mant times bewteen November and February 2017.  So a similar pattern again with it being seen this winter once again. 

"Yellow 2KRC" is a Little Marlow Regular. .
