edit: only realized now that I only scrolled halfway the thread and didn't see all other posts in between with more info about the mammals, and the post where you said you arrived! Anyway:
Bears are probably more in the C-Pyrenees (Val d'Aspe and surroundings, if any left, they are on the brink), Pyrenees Chamois, Pyrenees Desman (unlikely unless you prepare / have a good site / contact) and that's it for the (big) specialties.
Further on you have wild boars, wild cats, Isard, Marmots (introduced), Pine Martens,...
These were pleasantly confiding (Aspe valley, July 2021)!
