Our comparative analyses with @bksandercock.bsky.social and colleagues is now included in July issue of Oikos, and is making the cover, with a stunning picture of one of my great friend Verca. Read the paper here: nsojournals.onlinelibrary.wiley.com/doi/full/10....

Predator‐guild‐specific parental responses mitigate higher predation risk on ground nests close to forest patches in a mosaic landscape
Predation increases close to habitat edges, but how animals cope with local predation variations remained poorly studied. In a mosaic landscape, lapwings were compensating for increased nest predatio...

My mini-review in JAB on brood parasite adaptation and speciation was recognized top-cited article for papers published in 2024. Thanks to @avianbiology.bsky.social for the ERC Mini review contest and this opportunity #broodparasite #speciation nsojournals.onlinelibrary.wiley.com/doi/full/10....

Active defence mechanisms in brood parasitism hosts and their consequences for parasite adaptation and speciation
Obligate brood parasitism is a peculiar behaviour found in some bird species. The costs for their hosts can be high, generating selection for active defence strategies including foreign egg and chick....

I was very happy to present the study we performed (a bit less about the emergency baby poster 🐣) that would not have been possible without the work of @justinedelautre.bsky.social @ankitha-jayanth.bsky.social @ckecz.bsky.social #lapwings #behaviour at #EOU26 @eoufledglings.bsky.social

New article in Oikos with a global review of annual survival for waders comparing estimation methods and phylogeny. Survival increases with body mass but decreases with migration distance and during past 40 years. Team led by @dillensegerg.bsky.social. #ornithology #waders doi.org/10.1002/oik....

The Andean Altiplano in South America represents a remarkable mountain ecosystem with unique wildlife. However, knowledge of breeding ecology for birds inhabiting Andean Altiplano is scarce, relying ...

#iwsg2025 Is over, and I already missed it. Happy that so many people wanted to chitchat with me about my vaporware poster about 3D nest morphology, or about our( @dillensegerg.bsky.social ) project about Andean shorebird breeding timing! See you next year @waderstudy.bsky.social !

Throwback to 2021, when me and @dillensegerg.bsky.social had the honor to be invited to participated in the chaccu, the roundup of the vicuña to shear the wool. It was hard to chase them while running at >4.500 meters of elevation near Arequipa!

[Please RT] Our collaborative project #BDBORS exploring the link between nesting phenology and substrate property, is still ongoing, with collected data in Asia and America. You monitor ground-nesting birds in tropics? Then consider joining us! Contact me :) #ornithology #birds #tropicalecology

Justine Delautre, M1 student in our team from @master-rainet.bsky.social, successful defended her thesis on risks and consequences lapwings are facing when nesting close to forests. We hope to share soon the results with you #ornithology #conservation #PhD #lapwing #shorebird

Curlews eavesdrop on prairie dog alarm calls to avoid danger. Prairie dogs = "keystone information producers" 💚 This thread explains the study outcomes, and the photo of the "badgerinator" used as a predator proxy is just the icing on the cake. 🧪🌏 Paper: www.sciencedirect.com/science/arti...
