We are happy to announce that the next EOU Conference will be in Brno, Czech Republic in 2027! Check our website eounion.org and follow us on social media for regular updates! #ornithology #EOU2027

Hester and myself with her PhD hat.

Happy and proud of the next fledgling of the Flack flock. Dr Hester Brønnvik @hbronnv.bsky.social defended her PhD thesis today. She has done a wonderful job. I could not be happier! @imprs-qbee.bsky.social @animaltracking.bsky.social @mpi-animalbehav.bsky.social

🚀 Guess who’s back? 🛰️🥳💫
ICARUS, our global wildlife-tracking system, returns to orbit aboard the GENA-OT satellite, which launched from Vandenberg SFB today 🎉
This is step one for ICARUS 2.0: full global coverage, smaller sensors, near-real-time.
Congrats @animaltracking.bsky.social + team ICARUS

After the Ngogo chimpanzee group killed 21 members of neighboring groups and expanded their territory by 22%, female birth rates more than doubled and infant survival increased sharply—showing clear fitness benefits from intergroup killing. In PNAS: https://ow.ly/TKmf50XuPjY

Take three minutes to look at pretty birds, explore radar data, and see how we connect the structure of skies to MacArthur's ideas of niche partitioning. 📡🐦☁️🎧

More bad news for butterflies. Our new paper led by Wendy Leuenberger shows common species are declining even more rapidly than rare ones. @ZipkinLab

I found this in the forest next to my house today… any idea what on earth this could possibly be??? I am a biologist - but come on… this is sick!! I am sure these are 👾 that have arrived here without anyone noticing!!? 🤯

Es ist doch einigermaßen erstaunlich, wie ein komplett haltloser Vorwurf eines angeblichen Plagiats den Ruf und die Karriere einer Richterin bedroht, während ein ehemaliger Gesundheitsminister, der Milliarden versenkt, völlig unbeschädigt weitermacht, obwohl es Belege und heftigen Widerstand gibt.

In our new paper led by Ursula Heize, we show that >90% of #WhiteStork nests have anthropogenic materials (plastics, paper, etc). Ropes are particularly dangerous: ~12% of the chicks became entangled on ropes, particularly on baler twine!

2/5 We tracked 151 storks over up to 8 migrations (at 1 Hz!) to ask whether they improve their soaring skills to migrate efficiently. We identified > 55,000 soaring & > 6,000 flapping events that allowed us to compare flight across ages & seasons.

If there is an optimal behavior, why is there so much variation in the world? We found that, for white storks, context is everything. @anflack.bsky.social @mpi-animalbehav.bsky.social
