Today spent few min after my work on the Miedzyzdroje's beach. Despite a storm on the sea there were lots of BHG and Common Gull. I read one Estonian, white PP67 and controlled Swedish Common Gull!!! As you can see on the picture i added it a brand new red plastic ring T515 from our Polish project. From now it should be more recognizable and may get more recoveries.
