If you can read the ring number, then this can be submitted here: app.bto.org/euring/lang/... Somebody will then be able to get back to you with a history of the bird.

Graphic displays three images of Great Black-backed Gulls, one standing on a rock, one with a large fish it has caught, and one in flight. Text and labels highlight the species' bulbous bill and black back, which contrast with their surrounding white feathers.   
Caption reads: With a wingspan up to 1.66 meters, Great Black-backed Gulls are the largest species of gull globally. They're also the most predatory, often eating crustaceans, fish, and birds. 

Head to the coast for the best chance of sightings!

Incredible ringing recovery this AM by Stour Ringing Group of a Kestrel caught near Arne which was carrying a Dutch ring and a sat-tag. Well done for getting the data so quickly. Amazing movement for a bird that typically isn’t considered to move large distances. @dorsetbirdclub.bsky.social

Birds in Greenspaces | BTO About Birds in GreenspacesBirds in Greenspaces is a new, UK-wide citizen science survey of birds that use our public-access greenspaces. These spaces play many important roles for both birds and people, particularly in urban areas. For birds they offer resources and shelter that cannot be found in the surrounding built-up environment, and for people, are important hubs for socialising, exercise, and cultural activities. For many they are also the only accessible place to connect with the natural world, something which can be very beneficial for mental health.

Sign up to take part in Birds in Greenspaces and to receive updates via our newsletter at www.bto.org/greenspaces πŸͺΆ

This project starts in April and we need you to help tell us what birds can be found in your local greenspaces. 🐦🌳

A Long-tailed Tit perches holding a feather in its bill.  The bird shows pale underparts contrasting with darker wings and a long tail, distinctive black stripes on an otherwise white head, and blush pink on the breast, wings and eye-ring.

A Long-tailed Tit nest has been made to nestle in the meeting point of two branches in a spiky dense bush. It shows lichen camouflaging the nest, with a small open hole for the birds to come in and out of.

Did you know that Long-tailed Tits use thick layers of moss to build their nest, binding it together with spider webs to give an elastic effect? They also cover it in lichen to camouflage it from predators & fill the nest with over 2,000 feathers! πŸͺΆ

A fact box reveals more facts: their weight range (360g-480g), average age (11 years), diet (fish), number of eggs laid (1-2), when to see in the UK (year-round), and number of pairs in the UK (20k). 
The caption reads: Where would you rank the appearance of Black Guillemots alongside other UK seabirds? Their distinct black, white, and scarlet features certainly catch the eye!
