Scientists aren’t sure how they do it. Even complex algorithmic models haven’t yet explained the starlings’ acrobatics, which rely on the tiny bird’s quicksilver reaction time of under 100 milliseconds to avoid aerial collisions—and predators—in the giant flock. The birds tend to flock together for protection and can reach speeds of up to 20 mph.

Vimeo user Sophie Windsor Clive was recently canoeing on the River Shannon in Ireland when she witnessed the beautiful phenomenon.
