Bat Chat e-Download

Now in digital format and available as an instant e-Download! One of the most remarkable of bats' abilities is their biological sonar system called "echolocation." To chase down flying insects and avoid collisions in the dark, bats emit high-frequency beeps and analyze the echoes that come bouncing back. This PowerPoint presentation explains how echolocation works and how bats use it so effectively. Includes audio examples of actual echolocation calls.
