Across the world, a variety of animals that are normally diurnal (active during the day) are starting to increase their nocturnal activity. According to new research published in the journal Science, that’s likely because those animals want to avoid pesky humans.

“Many animals fear humans: we can be large, noisy, novel, and dangerous, and animals often go out of their way to avoid encountering us,” ecologist at the University of California, Berkeley and study author Kaitlyn Gaynor told Newsweek.
