A lot of the maps have random carcasses scattered about in different areas (I usually can't tell what they are, but there are dead Gargwas at the Misty Peaks map). Some monsters eat them. I've only ever seen Great Jaggi/Wroggi/Baggi do so, though. The bigger monsters tend to catch their own food rather than scavenge.
