Very happy to see this finally out! Thanks to all my amazing co-authors for this multi-year effort that we manage to wrap up! Coordinated transformations of the labyrinth and occiput during the dinosaur–bird transition | PNAS www.pnas.org/doi/10.1073/...

Un nuevo estudio ha redefinido la historia evolutiva de los canales auditivos de los dinosaurios que posteriormente evolucionaron a las aves modernas. Su reestructura no fue una adaptación para el vuelo sino que fue moldeada por la reorientación de la articulación cráneo-cuello.

Does the shape of the inner ear really make a difference to flight? It doesn't seem so! Congrats to the authors on this super cool work. Another example of ecomorphological relationships not being straightforward to understand👂 🐦 🦢 🦤 #oxipotangos

New paper today in @pnas.org, led by @gnavalon.bsky.social. We test the widespread assumption that changes in inner ear shape are a consequence of powered flight during bird origins. Turns out the orientation of the skull-neck joint explains changes from dinos better. www.pnas.org/doi/10.1073/...

Quite an updated and deep outlook on the main problems (and potential solutions!) in avian phylogenetics, past and present, stem and crown! Also very well written & nice to read, congrats you both (J. Benito is not in bluesky yet)!

This is soooooo cool! 🐦 🎶 Something that always made me wonder when birding in a tropical place is how different the bird songs sound to temperate places. Amazing work!

I have been hacked in X/Twitter so all my contacts if they receive some weird DM is not me! I am trying to get it back!

Great paper! A huge amount of effort went into the makings of this awesome work on passerine bird skeletal evolution, congrats everyone 🐦

Welcome Gorgonavis! First longirostrine enantiornithine out of China!

New paper out! 🐦📊 We realease AVONICHE, a global dataset with detailed information on the proportional use of 32 foraging niches, combining dietary categories with the behaviours and substrates used to access resources. Openly access the paper and data in GEB: doi.org/10.1111/geb....

Bowerbirds are Australo-Papuan birds engaging in some of the most flamboyant displays among vertebrates, and they might have been in New Zealand - Aotearoa in the Miocene too! Amazing descriptive research with a tinge of quantitative flair lead by @lizzysteell.bsky.social Check it out! 👇

This research mahi on the St Bathans bowerbird was led by the amazing @lizzysteell.bsky.social of the @fieldpalaeo.bsky.social lab. She is one of the up and coming palaeontologists working on passerines (songbirds) and definitely one to watch.

Welcome to the world Aevipertidus gracilis - the gracile one from a lost age. 14-19 Mya ancient #NewZealand appears to have had a bowerbird. Check out this amazing research mahi led by Elizabeth Steell (www.tandfonline.com/doi/full/10....). Artwork by Sasha Votyakova/Te Papa CC-BY-SA. 1/9 🧵

Sweet-looking postdoc with Chris Cooney (who is awesome) on perceptual bias and animal communication signals. FWIW, Sheffield seems to be a genuinely great place to live. www.jobs.ac.uk/job/DPB994/r...

🚨Anyone want a job?🚨 We have two #postdocs up for grabs! 🧪 - cell developmental biology/#evodevo/#neuroevodevo - bioinformatics and molecular biology Both working on brain evolution in Heliconiini butterflies Details below! Please repost 🙏 1/n

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

Exciting news at Cambridge! We are launching the Darwin-Hamied Centre to promote research at the intersection of biodiversity and economics christs.cam.ac.uk/news/darwin-.... We are advertising two 5-year Senior Research Fellowships—application deadline 22nd June! christs.cam.ac.uk/vacancies-ch...

Excited to share an invited commentary about the fantastic and ambitious work by @nicmalexandre.bsky.social and colleagues in @globalchangebio.bsky.social on Anna's Hummingbird beaks. It was a joy to write about, congratulations on a super cool study! onlinelibrary.wiley.com/doi/10.1111/...

🚨New paper alert!🚨 We show that hummingbird beaks have changed in shape & size since around WWII, driven by the rise of commercialized feeders! 🧵 📄 Paper: dx.doi.org/10.1111/gcb.... #ornithology #evolution #GlobalChangeBiology

Congratulations everyone involved, super beautiful specimen!

Congratulations, Lizzy!

Congratulations to @lizzysteell.bsky.social for the publication of her PhD magnum opus🥳🥳🥳New index to evaluate homoplasy in morph. datasets & tons of fun read about the effects of levels of homoplasy in macroevolutionary patterns! #homoplasyisnotdusty #superproud #doseefig6

Macroevolutionary integration underlies limb modularity in the origin of avian flight royalsocietypublishing.org/eprint/TNYK5...

A complete and dynamic tree of birds - out today in PNAS! Teamwork with @eliotmiller.bsky.social and others at @birdsoftheworld.bsky.social and Open Tree of Life to put together current relationships across all birds. www.pnas.org/doi/10.1073/...
