FERAL 1.0 is out! Just to remind you: FERAL is an open-source toolkit for supervised animal behaviour segmentation directly from videos with no pose estimation needed. We made it much easier to install and run FERAL First, to install FERAL: pip install feral www.biorxiv.org/content/10.1... 🧵

🦍 Camera-trap footage of chimpanzees & gorillas (PanAf500) We pushed FERAL to handle multi-species, multi-behavior field recordings: day and night, dense vegetation, variable lighting. FERAL achieves strong accuracy even for visually rare but distinct behaviors like climbing up/down.

A special issue of Science explores the complex and close associations rats share with humans—from their ubiquity in the human environment to their crucial role as biomedical models. 🐀 Learn more on #WorldRatDay: scim.ag/3E7Xo04
This photograph shows a female standard fancy rat—a domesticated variant for the pet trade. That rats make good pets is not surprising when considering the long history of their close associations with humans. Although brown and black "wild" rats do spread some infectious diseases, we have recently learned about more-positive attributes, including quite how adept, adaptable, and even fun-loving they are.
