An isolated skull from Las Hoyas (Early Cretaceous, Spain) informs the early evolution towards elongated rostra in enantiornithine birds (Aves, Ornithothoraces) The fossil record of Early Cretaceous enantiornithine birds from the Iberian Peninsula is the most significant in the world outside of China. Despite its historical relevance, taxonomic diversity, and...

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....

Thanks Emma! Anytime!! Madrid is a good place for macroevolution these days!

Thank you Steve!

Beyond excited to announce that as of today I officially started a Ramón y Cajal 5-year senior fellowship (tenure-track) at University of Alcalá in Madrid, if you are interested in birds & vertebrate macroevolution & you like sun & good food, hit me up to explore postdoc or PhD opportunities!

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

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 🧵

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)! 🧵

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!

Supplemental Feeding as a Driver of Population Expansion and Morphological Change in Anna's Hummingbirds Bird beaks are highly adaptable, with the potential to undergo rapid morphological shifts in response to environmental change such as climatic variation or food availability. Anna's Hummingbirds (Cal...

🚨New paper alert!🚨
We show that hummingbird beaks have changed in shape & size since around WWII, driven by the rise of commercialized feeders! 🧵

Whence the birds: 200 years of dinosaurs, avian antecedents | Biology Letters Among the most revolutionary insights emerging from 200 years of research on dinosaurs is that the clade Dinosauria is represented by approximately 11 000 living species of birds. Although the origin ...

If you want to know what's going in the field of Mesozoic ornithology we published today a review in #BiologyLetters @royalsocietypublishing.org focused on four anatomical systems!

Bird brain from the age of dinosaurs reveals roots of avian intelligence A ‘one of a kind’ fossil discovery could transform our understanding of how the unique brains and intelligence of modern birds evolved, one of the most enduring mysteries of vertebrate evolution.
