This year @birdsinwales.bsky.social kindly awarded us a grant to purchase trail camera equipment. @naturespy.bsky.social have also generously loaned us trail cameras. These cameras allow us to monitor Willow Tit nests at a landscape scale, gathering important data around the clock.

Our new research shows that HPAI increased Northern Gannet mortality by a factor of ~6 and ~4 at two of the world’s largest colonies. We predict this impact will take almost two decades to recover from. #biologicalconservation #seabirds #hpai Full paper: doi.org/10.1016/j.biocon.2026.111887

Review of the Week: 7-12 April 2026 Spring migration ramped up with some exciting continental overshoots, not least a Sardinian Warbler in Cheshire and a Marsh Sandpiper in Co Durham. Sam Viles reports:

White-billed Diver was the first bird I saw on the sea at Roseisle near Burghead, this afternoon. Hoping for more tomorrow 🤞. #birdingScotland

🚨NEWS: Here’s what you need to know: 🫸 From 1 May to 31 October, pause feeding seeds and peanuts. 🫧 Keep it clean: wash feeders weekly, change water daily, and move feeding spots regularly to reduce disease risk. ❌ Avoid using bird tables, as they can encourage the spread of infection.

🚨NEWYDDION🚨 🫸 O 1 Mai tan 31 Hydref, peidiwch â rhoi hadau na chnau daear. 🫧 Glanhewch y safle bwydo yn wythnosol, newid dŵr yn ddyddiol, a symud y safleoedd bwydo’n rheolaidd i leihau’r risg o glefyd. ❌ Peidiwch â defnyddio byrddau bwydo, gan eu bod yn gallu annog lledaeniad clefyd.

The first Osprey has returned back to Wales and to the Glaslyn Valley after a long journey from Africa. This is the first Osprey to return to a public nest as far as we know. Spring has arrived!🌸🦅☀️ @glaslynospreys.bsky.social

Mae’r Gweilch cyntaf wedi dychwelyd yn ôl i Gymru ac i Ddyffryn Glaslyn ar ôl siwrne hir o’r Affrig. Dyma’r Gweilch gyntaf i ddychwelyd i nyth cyhoeddus cyn belled ag y gwyddom. Mae’r gwanwyn wedi cyrraedd!🌸🦅☀️

Taking a dive into the wealth of data produced by users of @birdtrack.bsky.social and @birdsoftheworld.bsky.social eBird in Wales in 2025 for @birdsinwales.bsky.social Report. Number of users, records and time spent were up almost 20% on 2024. Thank you @btobirds.bsky.social for the data pack.

Valuable and interesting evening hosting, on behalf of @birdsinwales.bsky.social, the first online gathering of county bird recorders in Wales and those who verify records in multiple systems. It's a huge job undertaken by a relatively small group of committed and knowledgeable birders. Diolch!

Great to see effort to maintain co-ordinated annual monitoring of Green Sandpipers following the discovery, a few years ago, of the most important Welsh wintering site, and one of most important in the UK - paper in @birdsinwales.bsky.social journal Milvus. #BirdingWales

Lovely day @birdsinwales.bsky.social conference on Saturday. Lots of interesting talks and catching up with friends. Hopefully lots of people inspired to start doing some bird recording. Check out @btobirds.bsky.social surveys here www.bto.org/get-involved... or just use @birdtrack.bsky.social

Congratulations to Heather and Geoff on their awards today, and their two lifetimes-worth of service to ornithology in Wales.

I love the @birdsinwales.bsky.social conference. The venue, the talks, the food, the stalls, the raffle! All brilliant, da iawn! But I really enjoy the socialising. Break times are scheduled perfectly into the day to catch up, or meet new acquaintances. Annual selfie with BTO’s Gethin Jenkins-Jones!

WOS Conference 2025: 'Hear it! See it! Record it!' Great talks about the importance of monitoring & recording birds and flora & fauna sightings. Fab day👌🏼 @birdsinwales.bsky.social @rivers-disguise.bsky.social @penrhynbirder.bsky.social @cofnod.org.uk @btocymru.bsky.social @rspbcymru.bsky.social

Llongyfarchiadau unwaith eto @birdsinwales.bsky.social Great turn out, and fantastic speakers 👏🏼👏🏼

So well deserved! Both these individuals have played a part in where I am today - Heather via her amazing work on the Welsh Ringing Course (which I attended many moons ago!) and Geoff for entrusting me to monitor his Pied Flycatcher boxes until I relocated to East Anglia.

Diolch i @birdsinwales.bsky.social for letting me return to my Welsh roots and speak about @bto-gbw.bsky.social today. Great to catch up with folks and learn more about #WelshBird recording and how everyone can contribute!

HUGE diolch to ALL who supported and attended Conference. An inspiring, informative & wonderful day. See you next year! Diolch i BAWB am gefnogi a mynychu. Diwrnod ysbrydoledig, addysgiadol a bendigedig. Tan flwyddyn nesaf! @iolowilliams.bsky.social @btocymru.bsky.social @rspbcymru.bsky.social
