1/ We’ve been investigating Swift chick feeding rates using sound! 🔊 Swifts are declining in Wales, so @northwaleswt.bsky.social teamed up with us to research food availability during the breeding season by installing audio recorders at nest sites. 🎥 James Shrimpton #Ornithology #bioacoustics

We’re delighted our raptor monitoring project Cudyll Cymru has been awarded further funding so it can continue for the next three years➡️ www.bto.org/cudyll-cymru This project is funded by the Nature Networks Programme. It is being delivered by the Heritage Fund, on behalf of the Welsh Government.
We're working with @bangoruniversity.bsky.social and @btocymru.bsky.social to map swifts and swift boxes in North Wales! You can help by recording swift sightings: cofnod.org.uk/projects/swift-recovery Or email hrb21gsx@bangor.ac.uk with the location of swift boxes. Please submit records by 31 March
Learning how to nest record safely enriched my birding and completely changed the way I looked at birds and their behaviour in spring. Want so share this experience and gather vital data for @btocymru.bsky.social? This free online event on 17 March is for you: www.bto.org/our-work/eve...
