🚨 PhD offer (please share) Fascinated by bird migration and movement ecology? 🦜🌍 Join us at @vogelwarte.bsky.social to study annual cycle energetics with multi-sensor loggers in multiple species Deadline: 20 Feb 2026 Starting: June 2026 Supervision: Martins Briedis & me Info: tinyurl.com/2dbv9nzh

Happy to share our new paper published in @cp-iscience.bsky.social We deployed 300+ multi-sensor loggers across 17 species to investigate how different species adapt their flight strategies when crossing deserts and marine areas during migration. tinyurl.com/2c8y8xvf #ornithology #birds

Winter means.. communal roosts! 🦅🐦🦜 But why do birds form such roosts? In red kites, young single males are the most frequent visitors. Once paired, birds roost more solitarily, often together as a pair. 📢 Now online: tinyurl.tools/98e9279e @animalecology.bsky.social @vogelwarte.bsky.social

Happy to have contributed to a new paper on the wonderful Yelkouan shearwaters, highlighting just how vulnerable this species is to human-driven threats 🌊

Our team analysed the correlation of N deposition with numbers of territories of 112 Swiss breeding birds species. Insectivous and herbivorous species were more negatively associated with N deposistion, as well as ground-nesting species. Read more here: doi.org/10.1111/cobi...

Yesterday a game keeper asked me to safe a young kite that was stuck up a tree. It had one claw entangled in plastic. In eight years of ringing 1200 kites, I’ve seen every year chicks with ligaments entangled. Some 1-2 % already dies in the nest due to plastic. This one was ‘lucky’ to have fledged.

Spent a week in and around the forests with a nearly invisible beauty of a honey buzzards nest in a silver fir as the highlight of the week. These birds (and their social wasps) seem to have quite a good year.

Over the past 10 years I’ve climbed and controlled some 1000 red kite nests. Here a nest with two chicks that had an apple for lunch. Nutrient wise a useless prey but these birds bring all kinds of human refuse on their nests.

Somehow silly to endlessly keep debating about the basic consensus that the climate is warming due to human caused greenhouse gas emissions. Anyway, quite an insightful 🧵 here.

Raptor rapture in Georgia Ian Lycett discusses a memorable few days at Batumi in September 2024, where tens of thousands of birds of prey filled the skies:

A reminder to keep fighting for a better world. A healthy, inclusive environment doesn’t come for granted. Not even a million Nobel prizes are worth to maintain a toxic system.

How do ecological factors influence site selection in a Northern Wheatear (Oenanthe oenanthe) population in the Swiss Alps? Y. Rime et al. found that birds were attentive to exposure, slope inclination, and the presence of rockpiles. More on doi.org/10.1007/s103... #ornithology

Observing nests with camera's yields quite some fascinating by-catch. Here we see a wood mouse - Apodemus sp. on a nest in a tree crown at 22m. After the birds fledged, this mouse visited it almost every night. It shows that the used habitat of this animal doesn't just consist of the forest floor.
