Despite advances, quantifying complex motion info remains challenging. @jtroscianko.bsky.social @kevinjgaston.bsky.social &co present BehaveAI, a #video analysis tool that sees motion as color, tracking animals & classifying #behavior in complex natural scenes @plosbiology.org 🧪 plos.io/4kTF1wX

Illustration of the framework’s structure. Users can specify primary classes and secondary classes across both static and motion video streams (a–f). The right panel shows examples of static and color-from-motion frames from case studies. The color-from-motion trails create characteristic patterns that reveal movement and behavior. The grass moth (Crambidae) is nearly undetectable from still frames due to its color, and motion blur, but it is highly salient in the motion stream (g). The semaphore fly (Poecilobothrus nobilitatus) example shows how motion information can easily disentangle behaviors that are often identical from static frames (e.g., “fly” and “display” appear identical in the static frame, but different in motion). This example also showcases hierarchical classification, with secondary classifiers determining the sex of the flies (h). Sea slaters (Ligia oceanica) are highly camouflaged when static, and salient when moving, resulting in motion models that make far fewer errors (but cannot detect stationary individuals) (i). Human sperm have been classified based on their swimming movement with either symmetric (typically resulting in fast, straight movement), asymmetric (typically resulting in slow, circling, exploratory movement), or weak (twitching, vibrating etc…) strategies. These swimming strategies can be determined without tracking individuals, which is difficult in complex, debris-filled videos (j).

Last week we had two fantastic speakers join us at the University of Exeter Penryn campus @uniexecec.bsky.social for our annual Darwin Week celebration! Thank you to both @matteosanton.bsky.social and Andrew Hendry for each of your inspiring seminars and workshops. We have loved hosting you!

I wasn’t aware of how cute and interesting cuttlefish could be until @matteosanton.bsky.social showed us his research at @uniexecec.bsky.social Those pattern changes during predation are really mesmerising!🦑

Thank you to @asab.org for a wonderful conference in Liverpool last week. I had an amazing time chatting with ECRs in animal behaviour and listened to some fantastic talks! And thanks to Silverback Films for their engaging workshop on natural history filmmaking.🦕 #ASABSpring2025
