Environmental Variability Shapes Life‐History Trade‐Offs Within and Between Populations of a Long‐Lived Seabird Life-history theory predicts a trade-off between allocation of resources to reproduction or self-maintenance, yet how environmental variability shapes this trade-off remains poorly understood.

Some ominous footage gathered a few days ago from one of the Willow Tit nests we are monitoring. GSW are the most common predator of WT nests in Britain, and having increased by ~400% since the late 60s, it's not a threat that's going away. Let's hope this one has amnesia... #UKBirding #Yikes

Many Fulmars are now back on territory, including FP96412, ringed in 2011 and still happily residing along Head Dyke. Fulmars are among our longest lived seabirds, with some reaching over 50 years, so this one may be in the prime of its life.

NEW PAPER in #ornithology shows that some #seabirds have increased tremendously over the past decades - and that #UAV monitoring can reveal the full extent of these colonies: buff.ly/ocefm59

Variation in food availability affects the population age structure of Atlantic puffins Fratercula arctica in the Faroe Islands Across their entire Atlantic breeding range, Atlantic puffins Fratercula arctica have experienced decreases in food availability, often leading to population declines. The species is one of the most ....

‼️🚨New Paper Alert! 🚨‼️

Using a decades-long dataset on puffins in the Faroe Islands, we show a change in population age structure and relate the increase in older birds/decrease in cohort sizes to (pre-)hatch year food availability.

Innovative research suggests Bass Rock gannet colony may be stabilising after avian flu outbreak New research is shedding light on the health of one of the UK’s most important seabird colonies, suggesting it may be stabilising after the devastating outbreak of avian flu in 2022.

New research suggests gannet numbers on Bass Rock may be stabilising after a sharp avian flu-related decline. Emily Burton of the Scottish Seabird Centre notes breeding success remains low, so continued conservation is needed. bit.ly/47XFvgf

Investigating the impact of UAV noise on bird activity: A playback experiment

How does UAV noise influence bird behaviour and vocal activity?
We aim to address this using controlled, field-based playback experiments.

We would be grateful if you could take part in our 2026 Diversity and Inclusion survey 💙

Within The Seabird Group, we're tracking our progress and working to build a more diverse, inclusive community 👥

It takes just 5-10 minutes to complete ⏲️

Take the survey here:

Delighted to see our paper out today in Proceedings B @royalsocietypublishing.org! We investigated how kittiwakes adapt their activity patterns across latitudes in response to the changing day-night cycle ☀️🌃 In short - we find that Arctic kittiwakes don't have bedtimes.. doi.org/10.1098/rspb... 🧵1/4

Newly-developed attachment method for bird loggers Short-term tracking of birds often involves glue or tape attachments, which frequently detach prematurely, leading to data loss and potential harm to the birds.

Tracking #seabirds has become increasingly important to collect data about their space use - but how to attach the #loggers? Colleagues from @ninanatureresearch.bsky.social have developed a clamp system, which helps to keep loggers in place for several weeks to months. seapop.no/en/2026/03/n...

Our Belgian chiffchaff recovery is back! 🪶💍

It was ringed on 10th October 2025 in Liège, Belgium, and was re-trapped on 8th December 2025 in Cheshire, UK (669km movement). A small insight into where UK wintering chiffchaffs may breed (although it was likely ringed on migration). #ornithology

Puffins and Shags seem to have been hit hardest by recent storms, with many reports of birds washed ashore. This includes one Isle of May Puffin that was ringed as an adult in 1995, making it at least 34 years old!
