Any thoughts from more experienced wader ring readers - seems to match the Norwegian Barwit project on IWSG register, but not listed on www.ringmerking.no/cr/?
Red cr on left tib, engraved flag YN(EEH) on right tib.

Thanks to all at ECOTOP & @theseabirdgroup.bsky.social for organising such a great conference. Lovely to catch up with old friends, meet new ones, & learn more about the amazing breadth of seabird research going on around the world!! Also enjoyed my first poster session #CoimbraSeabirds

Lots of Puffins and Kittiwakes around to welcome us back to the Isle of May for the summer field season. Great to be back on the island and see it start springing back to life after a tough winter for many of our #seabirds.
