  • A biologist uses a high frequency audio mcirophone to record the audio signature of a bat that has been tagged with a light emitter. The pulsed light in this long exposure is created by the wing beats of the bat as it flew into the forest. The light emitter will fall off within a few minutes. Ochoco National Forest, Oregon.
