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.

Thanks to @emmaroddicksnp.bsky.social for raising the impact of fireworks on animals at First Minister's Questions. The delay to the licensing aspect of the Fireworks Act is hugely frustrating. The suffering animals continue to endure is deeply upsetting: www.onekind.org/blog/firewor...

As a county bird recorder I can honestly say that the best and easiest way for you to make your birding count, is to upload them to either eBird or BirdTrack. Doing so contributes directly to #ornithology and bird #conservation at both local and national levels.

We're incredibly concerned about the welfare of two satellite-tagged golden eagles, Tarras and Wren, that have recently disappeared in Dumfries and Galloway.

Anyone with information should contact Police Scotland.

A Manx Shearwater, which was found under a hedge in a Haddenham garden last Tuesday, was successfully released yesterday at Hunstanton. It was launched off the cliffs and flew out to sea. @cambsbirdclub.bsky.social #ukbirding

Swift conservationists seem to be pretty much unanimous: 2025 was an excellent year for nest numbers, brood productivity, and activity levels around colonies.

The main reason seems to be long spells of warm weather without much rain.

It's been a lot of fun watching Swifts nesting in my boxes for the first time this year. The first pair fledged 2-3 young in July but surprisingly a second pair started late and have just fledged 1-2 young in the last few days. Fingers crossed they are back next year @cambsbirdclub.bsky.social

Great piece. Swifts really are the best birds!
I’ve started writing on substack! Will be a lot of bird stuff, but also whatever comes to mind. For now I have posted a piece I wrote for friends at the beginning of summer about my favourite bird. A big piece about seagulls on the way for anyone interested… 🪶

Found a juvenile Cuckoo feather at the Research Park this weekend. Hopefully part of its moult before it begins the long migration south. The other photo was taken a few weeks back at the same site; juvenile waiting to be fed by Reed Warbler foster parents @cambsbirdclub.bsky.social #ukbirding

Amongst those arrested in London for peacefully protesting the genocide in Gaza is this blind person in a wheelchair.

Staggeringly embarrassing and shaming for Starmer.

Turkey reached 50.0°C for the first time in recorded history today (preliminary)

This isn’t just a heatwave, It’s the edge of human survival. In low humidity just 30 minutes of exposure risks heat stroke. Increasing humidity shortens that time.

This is climate change, and it’s accelerating.
