Thermal IR video showing bats emerging from Davis Cave.
Thermal IR video shows Brazilian free-tailed bats emerging from Davis Cave. These cameras have an automated image analysis system that detects, tracks and counts bats that emerge from the cave. In the video, first the original infrared data appears, then the detected bats are shown with white dots, and finally the tracked bats appear with colored trails.
