📄New paper out in Behaviour doi.org/10.1163/1568539X-bja10356

🐦 Ambush behaviour is rarely reported among #seabirds. We observed that #MediterraneanShag might employ this strategy to seize fish schools. Our knowledge on seabird #foragingbehaviour is still lacking!

A deceased Puffin lies on its back on the ground. Wording above reads: Please report sightings of all dead birds. A graphic showing an exclamation mark in a triangle features.

⚠️ We've had reports of seabirds washing up. Please report ALL species of dead birds ⬇️

Please keep an eye out for seabirds washing up on beaches - these prolonged storms seem to be having an effect. Report dead birds to Defra/Daera and BTO in the UK, live ones to suitable wildlife rehabbers.

Graphic Displays: An image on an Arctic Tern by Sarah Kelman/BTO next to a map with lines depicting their migration route from the UK to the Antarctic. Caption Reads: Imagine flying from the Antarctic to the UK and back every year for the best part of 30 years. With the longest migration of any Tern and a possible lifespan of over three decades, Arctic Terns can really cover some distance! #seabirds @btobirds.bsky.social @jncc.bsky.social @rspb.bsky.social

Marine pollutants disrupt cellular energy production in #seabirds

Higher mercury levels can make mitochondrial membranes more porous, reducing ATP production; high levels of certain PFAS compounds block a "safety valve", potentially causing a different type of oxidative cellular damage.

Symposia Symposia Each symposium will include a set of talks organized around the same central theme. While we expect a diversity of ornithological topics throughout the scientific program, we are happy to …

The call for symposium proposals for #AFOWOS2026 is open until January 18! A symposium is a set of talks organized a central theme and may be either a half or full day.

Last years field assistant holding a Manx Shearwater on the isle of Rum (under a towel), retrieving a GPS device after a bird has returned from a foraging trip!

We are looking to hire a Seabird Field Assistant for 2026 for our Manx Shearwater research project.

Please share this to anyone who'd like to get out in the field this summer and learn about biotelemetry, bird handling and research into animal behaviour.

Can we communicate our reaserch in more fun and accessible ways? I loved working with Anna @btobirds.bsky.social on her fantastic comic illustrating our recent work using seabird poo to look at their diet!

Graphic displays and image of a Storm Petrel by Joe Pender/BTO with the English and Latin names above it. To the right of the image is a map showing the UK and Africa. An arrow shows where the species breeds and winters, conveying the large distance between the two areas. Caption reads: 'Where to now?! A number of seabirds covered by the SMP are migratory, wintering away from the UK. Storm Petrels are a great example, wintering off the coast of southern Africa in the South Atlantic and Indian Oceans! #seabirds @btobirds.bsky.social @jncc.bsky.social @rspb.bsky.social'

Ocean warming threatens seabirds in the North Atlantic Climate change is causing ocean warming, acidification and loss of sea ice. This, in turn, is leading to shifting biogeographic distribution and in some cases species extinction.
