In terms of a non-invasive example, chimpanzees have become so effective at hunting red colobus monkeys that rcm populations have been in in decline and could become extinct due to the effectiveness of chimpanzee hunting.
Check out this dissertation titled, "The impact of hunting by chimpanzees (Pan troglodytes) on demography and behavior of red colobus monkeys (Procolobus rufomitratus) at Ngogo, Kibale National Park, Uganda" by then Yale PhD Candidate Simone Teelan https://search.proquest.com/openview/ad5b28c91ebbee41b36f166dfb953ac4/1?pq-origsite=gscholar&cbl=18750&diss=y
