Well, it's official. After our paper last year (onlinelibrary.wiley.com/doi/full/10....), the Slender-billed Curlew is officially declared Extinct today.

Scientists dream of describing new species, not writing their obituary and epitaph, knowing that they are gone forever #ornithology

Fascinating article making a reasonable case that this neolithic rock engraving from 2000-5000 years ago in Alta, northern Norway, shows a Great Auk (now extinct) being captured. onlinelibrary.wiley.com/doi/full/10....

This is a game changer for marine conservation. Now we need to build on the momentum and designate high seas marine protected areas to conserve Key Biodiversity Areas @keybiodiversity.bsky.social

BirdLife International @birdlifeglobal.bsky.social · 22d

🌊 A historic day for our oceans! 🌍

With 60 ratifications, the High Seas Treaty will now come into force – a milestone for global ocean conservation.
