We have a new group logo - honouring one of our key study species, the northern wheatear ๐Ÿ˜

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 canยดt see them on the bird ๐Ÿ˜‰

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 ๐Ÿงญ
in Northern Wheatears together with @annikapeter.bsky.social

Meet Matteo!

Our new @sfb1372.bsky.social songbird orientation fellow

With a background in waterbirds, he is excited to dive deeper into migration research

Originally from ๐Ÿ‡ฎ๐Ÿ‡น, he is strongly motivated to contribute to various research activities & firmly believes that lunch should never be rushed

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!

Weโ€™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

1. Yellow-browed Warbler tagged in 2025! ๐Ÿคฉ

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!

Meet Lasse,

Heโ€˜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, heโ€˜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 songbirdsยด droppings contain #microplastics

Meet Melanie: sheยดs 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.

Finally some fieldwork! It was great fun to support @giovannasandretti.bsky.socialยดs project tagging & sampling Northern Wheatears on the island of Norderney ๐Ÿ˜Š

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 methodsโ€”bird ringing and taggingโ€”with statistical modeling using Bayesian inference frameworks in Julia, R, and Stan.

Meet @giovannasandretti.bsky.social

She moved from Brazil to start her PhD on the autumn migration of Northern Wheatears using #Motus tracking. Her passions include ecology and conservation, especially with birds.

She is excited to her first field season on Norderney in the coming weeks!

You wonder what is our research about? See this word cloud, we collected, about our perspective of scientific fields and topics.

Meet Heiko, our group leader! Since kindergarten, he has been fascinated by #birds and has developed a deep passion for their spectacular journeys across continents. This amazing phenomenon motivates him to study their #ecology. He believes such research is essential for protecting #MigratoryBirds

We are happy to introduce our lab members - today: Annika @annikapeter.bsky.social!

She studies songbird navigation skills for her PhD & is fascinated by all kinds of birds & enjoys observing their behaviour, both at work & in her free time.

Wheatears have a special place in her heart โ™ฅ๏ธ
