Our new @science.org paper is out! Cuckoos and hosts are locked in a coevolutionary arms race over egg mimicry.

But how are these egg types inherited, and could this drive speciation? We sequenced hundreds of genomes to find out!

super cool study found human artifacts in Bearded vulture nests, incl. "weaponry like a crossbow bolt and wooden lance, decorated sheep leather, and parts of a slingshot....a shoe made from twigs and grass is ~675-years-old." link to paper: doi.org/10.1002/ecy..... www.popsci.com/environment/... 🧪🌍🦉

The Local Organizing Commitee welcomes behavioral ecologists from across the world and of all career stages to enjoy a five-day meeting rich in top-notch science and ample networking opportunities in Turin (Italy), 20-24 July 2026.

NEW PAPER: Red-breasted mergansers do not move parasitic eggs to cooler nest edges, suggesting limited use of discriminatory incubation against conspecific brood parasitism, though some eggs may be selectively removed.

Our fieldwork on brood parasitism of common cuckoos started well, with so far 11 caught individuals! When catching these charismatic birds, there are usually also interesting bycatches :) @ivb-cas.bsky.social @rytikerttunen.bsky.social @lisandrinamari.bsky.social

It’s all about eggs at BTO right now, but not the chocolate kind! 🐣 We’re busy during the nest monitoring season! 🐦 You can get involved too by watching birds in your garden and submitting records to our Nesting Neighbours scheme. 👉 www.bto.org/nest-mon...

So whose eggs are these? ⬇️ #Birds

The race is on! 📢 Six BTO Cuckoos have touched down in Europe! 🌍 So where are our frontrunners and who will be the first to reach the UK? 👇 www.bto.org/cuckoos #Ornithology #Birds

Birds are just very inventive creatures! 😀😉

We also tracked down a birder, Mr Otis from Reading, who was sitting on the dock of the bay in Southampton and caught a glimpse of a Cuckoo with a tag flying overhead! It must have been Tom cruising along to his Norfolk breeding grounds. What a journey! 🛥️🌍😀

#OIKOSFin2025 conference was great: high quality talks, well organized, nice atmosphere! A big thanks to organizers and all research group members 🙂

I am excited to announce that @neeltjeboogert.bsky.social and I are co-editing a special collection in the journal Animal Cognition on "Cognition in the Wild". Submissions are due by June 15. We are excited to see the amazing work you have been doing! link.springer.com/collections/...
