Lesser Black-backed Gulls pouring back into Guernsey and a Norwegian Great Black-backed Gull
With c 100 LBBG colour ring readings on each of the past two mornings at Chouet, the return migration is probably now peaking. Another nice surprise this morning was another immature Norwegian Great Black-backed Gull - the third seen this month.

Portuguese-ringed LBBG in Guernsey
Amongst 70 rings read on Lesser Black-backed Gulls at Chouet
this morning before work was a foreign metal ringed adult. Fortunately for me
this bird, probably a male due to its size and dominant behaviour, claimed a
position resting on a rock at close range. I managed to read the front four
digits of the ring and a part of the address. Then, less fortunately, the
recycling bins were emptied and the noise flushed the gull. I thought I’d lost
this record...but within 15 minutes the bird was back on the same rock…albeit
very briefly before it flushed again. However…my luck was in today…and I found
it resting on another rock at close range for a few seconds enabling all but the
final digit of the code to be read…so we should be able to narrow this bird down
to within 10 gulls. I’m not 100% certain yet, but I think the words “cempa
estado” on the ring indicate that this is a bird from the Portuguese ringing
scheme. The number was MO2782-
This was all around a lucky morning because the fog was once
again thick…and I feared that no ring reading would be possible.

Wonderful weekend at Chouet
This is just about peak spring arrival time for LBBGs in Guernsey, and it showed at Chouet this weekend. A couple of hours in the landfill produced stunning views of the gulls at very close range - and with c60 colour ring reads taken on each of two days there was plenty of action to enjoy. Many of the birds are freshly arrived back from wintering grounds in Iberia or northern France. The Iceland Gull was apparently seen again on Friday morning. At least five French ringed Great Black-backed Gulls were also present at the landfill.

First Guernsey Great Black-backed Gull Reported from Spain!
My thanks to Antonio Gutierrez and Ricardo Rodriguez for some superb detective work in working out the code on a colour ringed GBBG in Spain. Very careful examination of photos confirmed the bird seen just over the French border at Plaiaundi, Irún, Gipuzkoa, Spain on Saturday 03 March 2012. Yellow 0.FF8 is the very first GBBG ringed in the Channel Islands to be reported from Spain. Until this record the furthest SW of any of our birds had been reported was Vendée, France. Yellow 0.FF8 was ringed as a chick on 22 June 2010 on Crevichon, Jethou. It was seen three times in Guernsey in August 2010, but then not again until its sighting in Spain.
