A Great Great Black-Backed Gull
The last post about colour ringed gulls on this blog was about a rare movement, a Common Gull chick seen in North West Spain. We have now had another unusual movement to Spain from one of our gull chicks. Not only was it ringed on the same day, but it has been sighted only 7 miles away from our Common Gull! This time however it is a Great Black-backed Gull.
Thank you very much to Antonio for reporting this sighting. You can see more photographs of T:013 and other colour ringed gulls in North West Spain on his blog - http://gaviotasyanillas.blogspot.co.uk/.
We have only ringed 16 Great Black-backed Gulls so far in this project. Despite this small number we have had 3 other birds, all from the same catch, seen abroad; 1 in Germany and 2 in Denmark. Such a high return rate from so few birds really demonstrates the value of colour rings on this species.
The majority of gulls we ring in this project are Herring and Lesser Black-backed Gulls. So far this winter we have had lots of interesting sightings from across Europe and beyond, which will be the subject of the next gull post.
