Bands of feral rhesus macaque monkeys are roaming Central Florida. Last month, a video went viral of several monkeys charging at a family at Silver Springs State Park in Marion County. Scientists estimate there are nearly 200 primates in Silver Springs State Park alone. Another 72 have been spotted from Franklin County in the Panhandle down to Sarasota County. The monkeys, who live in groups, or troops, usually avoid people, but they can become aggressive if they feel their turf is threatened.
