A new study has revealed the devastating long-term impact of bird flu on Gannets ⚠️ Two of the world's largest Gannet colonies, including Bass Rock, are not expected to recover until 2041 after adult mortality soared during the 2022 outbreak. Discover more: www.rspb.org.uk/whats-happen...

1/ The latest Winter Gull Survey revealed that over the two decades since the last count, the total number of gulls wintering in the UK has decreased from 3.9 million to just under 2.5 million! 📉 #Ornithology #Seabirds 📖 Read the report www.bto.org/WinGSReport

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

The 2025 #seabird breeding results are in from the Isle of May: Razorbills fledged 0.63 chicks per pair - right on the long-term average. Even better: 91.2% survival, well above the long-term average of 83.9% Strong productivity + excellent survival = a really encouraging year for #Razorbills. 💚

Yesterday the Puffin army returned, creeping closer and closer which allowed us to do a whole-island count. A staggering 13,174 were counted rafting, the highest number since 1934! Today, they made their first 2025 landfall, two days earlier than the 2013-2024 first birds ashore mean. Welcome home!
