The Little Egret N6 that has been at the Gann since at least 21st July is one of the Mid-Wales Ringing Group's birds. From Tony Cross "the bird in question was actually the only one I have ever ringed (out of over 400) that wasn’t at Penrhyn Castle in Bangor! It was ringed as an adult at Llanon, Ceredigion on 30th April 2022. I caught this one unexpectedly whilst dazzling Whimbrel, it literally dropped out of the sky in front of me! Any future sightings of this or any of our other colour-ringed birds would be greatly appreciated and can be input at https://mid-walesrg.shinyapps.io/mwrg_sightings/ This will generate an immediate automated response containing ringing info, details of any subsequent sightings and a map showing all movements of that individual to date."
The Great Black-Backed Gull W230 posted previously is a local - from the Skokholm wardens "W:230 (MA37844) was ringed as a breeding adult in 2018. It has bred on the same rock here for five years but this year failed to fledge any young. It was last seen here 10 July and has been seen at Dale airfield in the winter of 2019-20 and at the Gann in the winter of 2020-21."
Ringers are very grateful for any information on sightings especially after the risks they take in handling birds like GBBs. It is only by monitoring ringed birds that so much has been learned about lifespan, breeding productivity and movements. The gulls roosting on the beach at the Gann recently have been a bit more relaxed and some even standing up to show their rings, unlike the one above. There are often one or two red-ringed local gulls in the beach roost or on the river gravel banks. The email if you see one is skokholmwarden@gmail.com
European colour-ring Birding is a good place to start for other ringed birds - https://cr-birding.org
