Antioquia Brushfinch - Atlapetes blancae - Birds of the World Species accounts for all the birds of the world.

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!

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) 🇪🇺

Exciting science news on plumage colouration and genetic variation from our colleagues!

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

Experimental test of the fitness effects of divergent marine–freshwater chromosomal inversions in stickleback under different salinity conditions - Heredity Heredity - Experimental test of the fitness effects of divergent marine–freshwater chromosomal inversions in stickleback under different salinity conditions

Really excited to share my first PhD paper about fitness effects of chromosomal inversions!

Using an experimental approach we explored if inversions involved in ecotype divergence in threespine stickleback affect fitness-proxies 1/🧵

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.

🚨 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.

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.

Birds of the World - AviList: A Unified Global Checklist of the World’s Birds is Now Available AviList, a unified global checklist of birds, that provides the most current and authoritative taxonomy of birds around the world was released today by experts in taxonomy, nomenclature, and bioinform...

A monumental taxonomy unification effort has just been published - thanks to all those who've collaborated for years to make this happen!

We question the abundance-occupancy relationships using ebird data - we find ~ zero correlation

Stunning 😍

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)! 🧵

Thanks a lot Dave, it was a real pleasure to have you as my opponent. I thoroughly enjoyed our discussion ☺️

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.
