How do flying squirrels use echolocation?

Flying squirls use echolocation more proficiently than their biological cousins, the flying squirrels, which effectively emit sounds in short bursts and listen carefully to the echo in order to determine the location, the size, and possibly the density of the objects that the sound waves bounce off of. The only thing that flying squirls do is make noise, ignore the echo, and crash into random and easily avoidable objects.
