Yesterday I was on the road with a bird-ring-recording enthusiast
from Leipzig. We went to a bone meal-dumb on which where about
500 forageing Gulls – in fact:
European Herring Gull Larus argentatus
Lesser Black-backed Gull L. fuscus
Caspian Gull L. cachinanns
Yellow Legged Gull L. michahellis
Common Black-headed Gull L. ridibundus
Mediterranean Gull L. melanocephalus

For all kinds of senses it was an amazing – maybe odd – experience
to appreciate these gulls in that gloomy surrounding!
