1/ We need you to make sure your local Greenspace is included on our map ready for the Birds in Greenspaces survey! ➡️ app.bto.org/birds-in...
You can use the map to search for mapped greenspaces near you, suggest new sites and changes to existing ones if there's something we've missed!

Longevity record!
Last night, @washwader.bsky.social recaught this Black-tailed Godwit, first caught and ringed 29 years ago.
The metal ring was wearing thin (and was replaced) but the bird is still going strong.
