Holding a wing horizontal: Roles for muscles of the pectoral girdle other than the main two flight muscles

open access: yesJournal of Anatomy, Volume 248, Issue 5, Page 830-842, May 2026.
This report explores which muscles of the pectoral girdle are employed to allow birds to hold their wings horizontally with a level aerofoil surface during a glide. Abstract Whilst many birds glide briefly with wings held horizontally, some species maintain this posture for extended periods during soaring.

Sedimentary Metagenomics Reveal Avian Community Transitions From the Last Glacial Maximum to the Holocene

open access: yesEcology and Evolution, Volume 16, Issue 4, April 2026.
We used sedimentary ancient DNA shotgun metagenomics to reconstruct past bird communities in northern high‐latitude environments. By using long time series and data collected across a large environmental gradient, we contributed in a unique and explorative way to the understanding of palaeoecological dynamics between birds and their habitat on the ...
