Watch the World’s Largest Bat Colony Spiral Out of a Cave and Fill the Sky

Here’s some amazing nature footage captured with GoPro cameras by filmmakers Cristian Dimitrius and Fran Hutchins, who traveled to Bracken Cave near San Antonio, Texas. The cave is the summer home of the world’s largest bat colony, with millions of Mexican free-tailed bats living there for about 6 months of each year.

“The emergence of these millions of bats, as they spiral out of the cave at dusk for their nightly insect hunt, is an unforgettable sight,” writes Bat Conservation International. And that’s the sight that was captured in the video above.
