Our new commentary rdcu.be/ftx6h in @natecoevo.nature.com written with folks from @inaturalist.bsky.social and @cornellbirds.bsky.social shows that use of AI to manipulate existing or create new wildlife images undermines the huge value of vast citizen science databases. 🌍🪰🪶 #Ornithology 🧵 1/10

Citizen science platforms must mitigate against the threat of generative AI

🐦🌙 Happy to see this big collaborative paper out in @currentbiology.bsky.social! We address a seemingly simple question using geolocator data collected across many species and individuals: how much of bird migration actually happens at night? www.cell.com/current-biol... A short🧵

Critically endangered, the Antioquia Brushfinch is range-restricted to the northern Central Andes in Colombia. In 1971, this small bird was considered extinct but was thankfully rediscovered in 2018. Recent expeditions have found even more viable populations! birdsoftheworld.org/bow/species/antbrf1

Wonderful feature. Thanks!

New story on the Avian Hybrids blog! One gene to rule them all: Reshuffling of genetic variants explains plumage patterns in wheatears avianhybrids.wordpress.com/2026/02/04/o... Based on the Science paper by Dave Lutgen and his colleagues | #ornithology

Happy to share our new paper published in @cp-iscience.bsky.social We deployed 300+ multi-sensor loggers across 17 species to investigate how different species adapt their flight strategies when crossing deserts and marine areas during migration. tinyurl.com/2c8y8xvf #ornithology #birds

Based on thousands of citizen-science observations across Italy, our study shows that many hunted game bird species 🐦 start their pre-breeding migration earlier than reported in the European Commission’s “Key Concepts Document” (KCD) 🇪🇺 www.researchgate.net/publication/...

1/9 New in @science.org www.science.org/doi/10.1126/science.ado8005 How does genetic architecture constrain evolutionary trajectories? To address this question, we inferred the genetic architecture of convergent plumage coloration and its evolutionary history in wheatears.

Very very happy to see my PhD work out! Congrats to the whole team 🎉🎉🎉

🚨 First PhD chapter is out! My work thus far, with @andy2dobson.bsky.social We found that formerly common species have declined the fastest, on average. 📄 North American bird declines are driven by reductions in common species | Science Advances www.science.org/doi/10.1126/...

North American bird declines are driven by reductions in common species

Declines in North American birds are driven not by rare species vanishing but by sharp losses among formerly common species.

Choosing between Cerrado and Chaco: Which corridor connected the Andean and Atlantic forest populations of the Buff-browed Foliage Gleaner?

Genetic study provides several lines of evidence for a Cerrado connection.

Coming soon! A mid-summer special BOW Discovery Webinar on AVILIST - the world's first unified global checklist of birds. Does this sound good? Would you like to join us? Stay tuned for more info. Target is late July. We'll do our best to make this during a globally friendly timeslot.

A monumental taxonomy unification effort has just been published - thanks to all those who've collaborated for years to make this happen! birdsoftheworld.org/bow/news/avi...

The biggest "meta-analysis" ever? - 17 million effect sizes - elifesciences.org/articles/95857 With wonderful @coreytcallaghan.bsky.social and Will Cornwell We question the abundance-occupancy relationships using ebird data - we find ~ zero correlation

Millions of birds nest in the Arctic each year. But did you know they’ve been doing this since the Cretaceous? Can’t believe I finally get to share that our paper on the birds of the Prince Creek Formation is out in ‪@science.org (and on the cover)! 🧵 Art: Gabriel Ugueto ‪@serpenillus.bsky.social

Congrats to Dr. Dave Lutgen at U Bern for a damn fine dissertation defense today! Keep an eye out for some quality wheatear genomics in the near future, avec Reto Burri and Katie Peichel et al.
