Identifying gulls is difficult and I am no expert. But this one has an easy to read number on the ring and I reported it as a Caspian Gull (Larus cachinnans, 🇩🇪 Steppenmöwe, 🇵🇱 mewa białogłowa), second calendar year. I will see if my ID was right :) #birds #birdphotography #birdsofmastodon #birdwatching #nature #naturephotography #vogelflausch #ptaki
