These trajectory data enable us to study behavi oral states and identify ecologically significant foraging zones. However\ , modeling how environmental variables (like wind\, sea surface temperatur e\, or currents) shape these trajectories remains largely unexplored. Traj ectory simulation using generative artificial intelligence has shown great promise in fields like autonomous driving and human motion modeling. Insp ired by these advances\, we introduce a novel approach in movement ecology by adapting DiffTraj (Zhu et al.\, 2023)\,a pretrained diffusion model or iginally developed for vehicle trajectories. We then adapt and fine-tune t he model on seabird movement data\, so that it supports multi-species\, mu lti-site simulation\, with the aim of environmental conditioned generation \, and improving state-of-the-art seabird trajectory simulation.\n\nSeabir ds\, Trajectories\, Environmental variables\, LabéliséHallesIA ATTACH;FMTTYPE=image/jpeg:https://isdm.umontpellier.fr/wp-content/uploads/ 2025/06/ml-mtp.png END:VEVENT BEGIN:VTIMEZONE TZID:Europe/Paris X-LIC-LOCATION:Europe/Paris BEGIN:DAYLIGHT DTSTART:20250330T030000 TZOFFSETFROM:+0100 TZOFFSETTO:+0200 TZNAME:CEST END:DAYLIGHT END:VTIMEZONE END:VCALENDAR
