Brilliant work by Devi!

Poster for a seminar - Talk abstract: Vagrant birds were historically neglected in migration research due to their rarity and the limitations of early tracking methods. Yet, growing research shows that vagrancy can help us better understand several aspects of bird migration and its consequences. In this talk, I will show how abnormal migratory movements can inform key processes in bird migration, including the colonization of new territories, the emergence of novel migration routes, and the navigation systems of migratory birds.​

This week's seminar will be given by @pauldufour80.bsky.social of @vogelwarte.bsky.social on how we can understand bird migration through the study of abnormal movements such as vagrancy. Lecture held in @biology.ox.ac.uk at 3.30 on Fri 13 March - all welcome; online joining instructions ⬇️

Ancient DNA and spatial modeling reveal a pre-Inca trans-Andean parrot trade - Nature Communications Here, the authors combine ancient DNA, stable isotopes, and computational modeling to study colorful feathers from a pre-Incan tomb in Peru. They identify four species of parrots, which were likely ca...

🦜🏔️ How did vibrant Amazonian parrot feathers end up in a desert tomb on the Pacific coast of Peru 1,000 years ago? Our new paper on @natcomms.nature.com reveals they didn't just trade feathers, pre-Inca societies transported live macaws and parrots across the Andes!👇 www.nature.com/articles/s41...

Oxford friends! I'm giving the @egioxford.bsky.social seminar on Friday. Pop along! egioxford.web.ox.ac.uk/event/adrift...

Led by my talented PhD student @justine-armg.bsky.social we’re running a #meta-analysis of #cross-sex-genetic-correlations in fitness components.

If you have unpublished data or know of studies that might not appear in a systematic search, please reach out, we’d love to include them!

Please share!

Excellent to see Daisy presenting this work at a major network conference

A woman standing behind a desk at the front of a lecture hall. The slide behind her reads how does the pattern of node removal, and way network compensates, affect network metrics? In real world animal social networks

A great privilege to give my first conference talk at #NetSciX2026 in Auckland on some ongoing work with Adelaide (Daisy) Abraham on social compensation strategies when individuals are removed from real-world animal social networks.

Daisy also present a poster on the work which inspired this - on her birthday no less! Preprint is in the works on the responses of great tit social networks in response to experimental sex segregation.

🔈New study!

Microplastics found in 62% of White-throated Dipper broods in Scotland & Basque Country. No body condition effects detected.

Great pre-print led by @davididiaquez.bsky.social discussing possible causes of declines in adult and nestling mass. I suggested it be titled "Weapons of mass reduction"

Thanks, Louis! Yes, selective disappearance is a real possibility. Haven’t tested whether the process within cohorts reflect a within individual change, yet ;-)

Finally, this work wouldn't have been possible without the help of the endless number of field assistants, PhD students, postdocs and fieldworkers that obtained the almost 95,000 measures used in this study and without the support of @biology.ox.ac.uk @ox.ac.uk and @egioxford.bsky.social.

This work, as many others using long-term data, highlights the relevance of continuous systematic monitoring of natural populations to increase our understanding of how phenotypic traits respond to environmental change, and of the complex, life-stage-spanning mechanisms that underpin those responses
