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...

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.

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)! 🧵

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!
