Help us find ticks in Germany! NABU has launched a nation wide effort to understand the range expansion of ticks in Germany. With changing climates, tick species have been able to extend their ranges. You can help by reporting tick images as explained below: www.nabu.de/tiere-und-pf...

“we are trapping 21st-century minds inside 19th-century academic hierarchies.” This essay gets a lot right about problems with German science. I would add that the hierarchies and precarious contracts lead also to systemic abuse and scientific misconduct. open.substack.com/pub/realimag...

This #InternationalDayofWomenandGirlsinScience I would like to say a big THANK YOU to the amazing women and girls I currently have the pleasure of sharing my #ternscience journey with. Onwards and upwards we go! ❤️

A richly rewarding two days reviewing @ifv-whv.bsky.social: thriving under the brilliant leadership of Sandra Bouwhuis & Miriam Liedvogel. An exciting programme of research into avian migration & life histories with many future stars. Outstanding @commonternproject.bsky.social museum by frozen sea!

Are you interested in PFAS and OCPs contamination in birds? In our latest publication, we studied the levels of these contaminants in Great tit eggs from areas with different anthropogenic pressures. Read the paper here for more details👇 doi.org/10.1007/s113...

**PhD opportunity @uniexecec.bsky.social** How is immunogenetic variation maintained in the wild? Why are alleles that increase disease susceptibility maintained in populations, when natural selection should eliminate them?

*PhD opportunity @uniexecec.bsky.social* How does antimicrobial resistance spread through ecosystems? Combine fieldwork (rodent trapping 🐭, habitat surveys 🌳, pheasant sampling 🦤), molecular techniques, GIS, and spatial modelling to understand AMR evolution and spread. 🔬🦠🧪 Please repost!

Out @animalecology.bsky.social today - a paper with David Ewing in which we explore the #HPAI outbreak in the terns. We find bird-to-bird transmission to be the main driver of infection and estimate the probability of mortality to drop from 0.26 to 0.14 from 2022 to 2023: doi.org/10.1111/1365...

With @romain-pigeault.bsky.social and Jérôme Moreau we offer a 6-months internship for a master student to test the effect of pesticides on passerine birds. Follow the link for more. @ecophycebc.bsky.social @univ-larochelle.fr @univpoitiers.bsky.social www.linkedin.com/posts/corali...

When we hypothesised female terns to have lower mercury levels than males due to egg laying, @matteobeccardi.bsky.social et al designed an elegant experiment to prove the effectiveness of this pathway. That proof just got published & the open access paper can be found here: doi.org/10.1016/j.en...

Another excellent paper by @matteobeccardi.bsky.social, with great help from Justine Bertam, @commonternproject.bsky.social, @pablosalmon.bsky.social, @icbm-uol.bsky.social

🚨 PhD alert 🚨 We are looking for a highly motivated student to use 🧬 genomics 🧬 and 🛰️ bio-logging 🛰️ approaches to disentangle cultural and genetic contributions to seabird migration 🐣 Think this is you, or someone you know? Then come to our Q&A session at on 29/09 and check out the ad below!

How can we reform science? I have some ideas. But I am not sure you’ll like them, because they don’t promise much. elevanth.org/blog/2025/07...

Our neighbours at the Banter See are no fan of the terns. Luckily the terns don't give a shit. Oh, or maybe sometimes they do. :-)

Hatching is hard work. ❤️

Happy to share our newest paper in which we investigated the non-breeding distribution of Australasian gannets #seabirds #ornithology @aurore-counilh.bsky.social www.int-res.com/abstracts/me...

Live from the field: the first 4 chicks of 2025 have hatched. ❤️ #babyboom

I am looking for a postdoc wanting to use functional genomics to understand why birds 🐦 struggle with climate warming in @erc.europa.eu project #HotLife. Ideal candidate is a molecular evolutionarybiologist. Join us at @biologylu.bsky.social. Details 👇 shorturl.at/wijEq Would appreciate a re-post!

Last weekend was exciting! Together with @gullbilledterns-de.bsky.social,‬ and thanks to the amazing teams at Druid & Interrex, we deployed the first gull-billed tern with a GPS. It returned to the nest after a quick preening session and for the last 3 days has shared its foraging sites with us.

Really worth a read if you are interested in life-history physiology or mitochondrial function 👇

Now 11 birds recaught 😎 new pressure loggers giving insights into migration I never thought possible, absolutely incredible technology. Wouldn’t be possible without the help of friends here in Georgia, Levan, Sopo, Vano and Natia 🇬🇪 ☺️

Chapter 10 is dedicated to the Banter See common terns, showing how they too have suffered from a population crash following the outbreaks of avian influenza in 2022 and 2023.

meanwhile in #Georgia - where and how long do #blackcaps breeding in this eastern #location migrate? @joewynnbirds.bsky.social @andalgalornis.bsky.social and @oscarvedder.bsky.social are on a mission & have already caught 9 returning #geolocator birds. stay tuned! @ifv-whv.bsky.social

And here's another shout-out to the wonderful tern-and-quail team, which, led by Nathalie and @matteobeccardi.bsky.social, prepared a gorgeous hat for Justine. ♥️

Yesterday, Justine Bertram, the lovely soul in the center of this picture, successfully defended her PhD thesis. As throughout her time with the terns and at the @ifv-whv.bsky.social, she did a brilliant job. I could not be more proud, or sad that she is fledging now.

More loveliness today: half of the F1 joined for the morning observations (and took 267 photos of terns), and we spotted a colour ringed bird. Turned out to be one of our 'own' 2022 chicks, who received her additional bling on migration.

Live from the field: the first egg of 2025 is a fact! Laid by a lovely geolocator lady, while her ringed partner looked proud. Mum is incubating, and dad is off now, presumably to catch her a fish. ♥️ #firstegg #seabirds #ornithology

204 birds have now been registered by the automated registration system. Yesterday, one of our favourites returned too: 11-yr old Dextro, to us better known as our ‘bouncer boy’, because he’s the one that nests just behind the spot where we tie our boat and tries to keep us out of the colony. ♥️

They're back! The first three terns arrived yesterday morning. The very first one was 18-year old Calimero. He was followed by 7-year old Severina and 13-year old Fabrice. All arived between 10:29 and 10:54. ♥️ #phenology #seabirds
