  • A pettersson high-frequency recording/listening device designed to detect bats and record there calls.

  • 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.

  • Humboldt University professor of bioacoustics Joe Szewczak holds a patterson ultra-sonic bat detector and recorder that will automatically record the calls of bats that fly near. The device is set-up in the field after nightfall. The Nature Conservnacy's Dutch Henry Falls preserve in central Washington.

  • The path of a big brown bat (Eptesicus fuscus) is traced in this long exposure. Bat researchers attached a small light to the bat before releasing it to fly so it's high-frequency calls could be recorded by scientists. The light falls off after a few minutes. Ochoco National Forest, Oregon.
