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.

Worrying reports of bird flu (avian influenza) are coming in, including an outbreak in Whooper Swans in the Fens. Other waterbirds are also being affected, and cases are rising.
