Out now in Movement Ecology: We used multi-sensor geolocators to track myrtle warblers breeding in Alaska and found that they migrated much farther than expected to the Gulf Coast—rather than to the closer Pacific Coast non-breeding area 🪶🧵 link.springer.com/article/10.1...

🚨 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

Important milestone for the project and huge amount of work by @lvandenabeele.bsky.social to set up a pipeline for both investigating the systematics and characterising structuring reticulation events across the diversification of bee orchids (Ophrys): www.biorxiv.org/content/10.6...

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

NEW PUBLICATION on stopover ecology of Songbirds during spring migration: After packmor et al. 2020 (Mov Ecol) found that trans-Saharan migrants react differently to weather for migratory departure, we aked ourselves, whether this is also valid for spring migration? 🐦

Bogong moths use a stellar compass for long-distance navigation at night - Nature Every spring, Bogong moths use the starry night sky as a compass to navigate up to 1,000 km towards their alpine migratory goal.

The Australian bogong moth uses the Milky Way as compass during annual 100-mile journey to cool caves. This is shown by a groundbreaking study also revealing that the Earth's magnetic field plays an important role in the navigation of this mysterious moth. www.nature.com/articles/s41...

Great progress on the sib genoscape project with freshly collected reference samples of Little Buntings (and Red-flanked Bluetails) from the western part of their range. A very nice and successful fieldwork with @joewynnbirds.bsky.social ! #ornithology

Our PhD level course Ecology of Animal Migration at @biologylu.bsky.social is now open for applications! The course will run this November (3-14th) and cover various theoretical and practical aspects of migration ecology.

Two hybrid Coenonympha species inherited most of their genome from one parent species but prefer mating with the other! By analyzing chemical profiles, we show that non-random trait sorting likely drives reproductive isolation, fueling hybrid speciation
