Opportunity! We have an #internship offer through the RISE program. This applies to undergraduate students studying at North American, British or Irish Universities. If you are interested in doing fieldwork with us next spring/summer, have a look at the RISE website: www.daad.de/rise/en/rise...

In our new study, we investigated correlates of reproductive timing in Northern Wheatears on Norderney. Our results highlight the importance of conserving natural dune habitats, maintaining rabbit populations, and avoiding further expansion of anthropogenic areas. doi.org/10.1007/s103...

Last weekend, we joined #EOU26 in Gdańsk, sharing insights and results from @thiemokarwinkel.bsky.social and @giovannasandretti.bsky.social, with travel support from the @dornitholges.bsky.social Great atmosphere with lots of discussions and exchanges!

Session 8 at #EOU26 focused on biologging Thiemo Karwinkel, Susan Ellen McKinlay, Giovanna Sandretti da Silva, Ryan Boswarthick and Trevor MacLaurin on tracking movements, flight behaviour, survival, and tag effects. A lot of insight from these approaches—what stood out to you?

We have a new group logo - honouring one of our key study species, the northern wheatear 😍 And of cause, this bird is also tagged with a transmitter - but the tracking devices we use for our studies are so tiny, that you can´t see them on the bird 😉

A warm welcome to @mguidotti29.bsky.social who joined our lab now as an @sfb1372.bsky.social fellow In the next 10 months he will work on orientation 🧭 in Northern Wheatears together with @annikapeter.bsky.social

In cooperation with RWE, we proudly announce the installation of the first #MOTUS station in an offshore wind farm (Amrumbank West) in Germany and in Europe. This will help to fill key knowledge gaps in offshore environmental monitoring. We were supported by our colleagues from Wind Energy Systems

A skylark I tagged last autumn in northernmost Germany with a #Motus transmitter (to study #pesticide effects) was now detected near our University in Oldenburg - we @migecol.bsky.social col.bsky.social now have data from 3 migration seasons for this bird! motus.org/dashboard/#e... #birdmigration

We’re hiring a doctoral researcher in the area of migration ecology. The work will focus on the question of how and when migratory songbirds learn where their home is using #Motus. Part of the Cluster of Excellence NaviSense and linked with @sfb1372.bsky.social uol.de/job788en #ornithology

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? 🐦 a thread 🧵 on 7 hypotheses:

the 5 study species: Dunnock, Northern Wheatear, European Robin, Common Redstart, Garden Warbler

1. Yellow-browed Warbler tagged in 2025! 🤩 On September 24, @annikapeter.bsky.social tagged the first Yellow-browed warbler (Phylloscopus inornatus) on Helgoland in 2025 to study its migratory behaviour. Stay tuned for fascinating bird tracks! #Motus #Tracking #Birdmigration

Meet Lasse, He‘ll support the working group as a volunteer for the next year, hoping to learn and observe scientific work in the process. While his interests lay elsewhere beforehand, he‘s become curios about the groups work and likes to try to think along :)

This week we were at #BESMove2025, where @giovannasandretti.bsky.social presented our results on the overlooked pre-migratory flights. The conference title of this year was "Understanding Migration", and she came back home full of fresh insights and great new connections!

Great fun to teach students how to catch and handle #birds for scientific studies and how to collect and analyse fecal samples together with @giovannasandretti.bsky.social - but shocking to see how many songbirds´ droppings contain #microplastics

Meet Melanie: she´s the good soul of the working group and our secret star. Nothing works without her & everything works with her. Our technician can do everything & saves the rest of us from putting our foot in our mouths. She is also into plant conservation: www.youtube.com/watch?v=-_0W...#isoetes

We are happy to announce that the excellence cluster navisense just got funded - one of the biggest achievements possible in German research funding! We will contribute to the interdisciplinary understanding of bird orientation and navigation from social perspectives, to ecology and physics.

Introducing Georg: Ornithologist and movement ecologist in our group, specialising in passerine migration, with a passion for warblers and chats. His work combines hands-on field methods—bird ringing and tagging—with statistical modeling using Bayesian inference frameworks in Julia, R, and Stan.
