Stunning footage from a Ugandan national park shows a surprising scene—predators like snakes and birds feasting on fruit bats, which are notorious carriers of viruses like Ebola. Scientists think this messy buffet might explain how deadly pathogens jump from bats to other animals (and eventually humans).

Editor’s Note: Most people don’t picture a snake snacking on a bat as a public health concern, but these predator-prey interactions could be a missing link in how viruses spill over into new species. Understanding these chaotic moments in nature might help us predict—or even prevent—future outbreaks.
