Siberian Flying Squirrel: The 300-Foot Leap in Darkness

At 2:17 a.m. on July 14, 2021, a Siberian flying squirrel named Lunokhod launched from a larch branch, sailed across a 300-foot gap, and landed weightlessly on a trunk nobody had ever seen a squirrel reach before. Lunokhod wasn’t just chasing food-acoustic sensors along the forest floor recorded that he hadn’t made a sound, not even on impact. The thermal drones used at Tomsk State University logged the midair path: forty meters off the ground, with zero wind. But hunters had noticed something stranger-some squirrels arrived at specific mossy landing pads on the darkest, moonless nights, timing their glides down to the minute. For two years, researchers tried night-vision cameras, radio tags, even ultraviolet dust on the launch sites, but none explained why squirrels in the same colony picked different routes depending on the weather, or why the youngest gliders made braver leaps than adults. Then in 2023, while imaging Lunokhod’s whiskers after a record-breaking leap, a team found the payoff: Siberian flying squirrels have a special tuft of whiskers packed with nerve endings that sense the movement of air itself, letting them navigate around unseen branches mid-flight-even when they can’t see anything at all. For Lunokhod, those whiskers meant he didn’t just land, he landed on a spot only he could feel.
