Very impressed Sam!
Med Gull yellow ATHT was at the Gann on 17th January, see here for more details: https://pembsbirds.blogspot.com/2020/01/gann-gulls.html.
I had another new Med yesterday at the Gann, red ZHT4, which was ringed as an adult in the Czech Republic in 2019 and this was the first ever re-sighting of it. I also saw white ringed 3LX9 again yesterday, and another which I believe was 3VAR but couldn't be sure...
