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.

New large-scale study based on SEAPOP data shows that #ocean #warming threatens #seabirds in the North Atlantic

Loggers attached to birds can affect foraging behaviour Loggers have become a central part of research on seabirds and other groups of animals over the past 20 years. In seabird research, loggers provide very useful documentation of diving behaviour…

#biologging #research is booming - but do #loggers actually impact the birds? Yes, they do - depending on the mass and attachment location. If you work with biologging, you should read our latest publication seapop.no/en/2025/11/l...

Seabirds are more likely to ‘divorce’ in bad weather Wild seabirds are more likely to split up in windy weather, according to a new study involving the UK Centre for Ecology & Hydrology.

Importantly, birds that remained with the same partner tended to lay eggs earlier, which is strongly tied to how many chicks they rear 🐣.

Seabirds in crisis: Plastic ingestion induces proteomic signatures of multiorgan failure and neurodegeneration Plastic consumption in seabirds causes blood signatures of widespread organ damage including brain, stomach, kidney, and liver.

🍽️🐦 Proteomic studies reveals that #Seabirds with plastic in their stomachs had signs of neurodegenerative disease, kidney and liver disease as well as damage to the lining of the stomach

☠️While not always lethal, microplastics will undoubtedly have long-term effects on populations.

To protect wildlife as offshore wind grows, we need the best ecological data. Monash University researchers created a practical guide to seabird flight—how high, how fast & when they fly.

Avec l'accord de Marine Joumard, la fabuleuse illustratrice de "l'éthologie (presque) facile", j'ai eu envie de vous présenter les étapes de création de la couverture du livre. Et pour fuir les algos, je l'ai écrit sur MON BLOG (ET OUAIS): www.leniddepie.com/2025/02/07/u...

Je crois qu'il devient clair que nous, scientifiques, avons un rôle majeur à jouer pour former et informer les citoyens. Il faut plus de culture scientifique !

I don't know who are the 2 partners in 2024 but I have never recorded before such small egg for 1st time breeders aged 3 years old
I think it's due to environmental conditions especially with warmer SST
