Great work, Toby 👏. Hope you get some good resightings. You never know, but one or more if them might turn up @theroyalparks.bsky.social 😀

@patriciastoughton.bsky.social It's from Norway! You can submit it here as well post@ringmerking.no

@g76birder.bsky.social Do look out for any of any of 'my' London brds (c/r white U300-U599). Though, I suspect most of mine remain largely within the M25 and the majority seem to come into central London to moult rather than leave it. But you never know... 🤞 @kanebrides.bsky.social

Agree

You did better than me @mothyblackburn.bsky.social . Just 4 Tachystola acroxantha in/around my trap in Ealing this morning.😞

@patriciastoughton.bsky.social 🧵2/2.... If you seen any other metal-ringed birds in future the they can always be reported via app.bto.org/euring/lang/... or colour-ringed birds through app.bto.org/euring/lang/...

@patriciastoughton.bsky.social Here is a the ringing-resighting history of the #blackheadedgull you reported. It seems to show winter site-fidelity, but will leave for its summering area (probably in Continental Europe or Scandinavia) in the next few weeks. 🧵1/2
