Analysis of bird and bat flight with computer vision algorithms provides a new perspective on how animals move through threedimensional space. This is important for understanding the intricacies of flight and the interactions of airborne animals that fly in groups. Results can be applied to a large array of tasks, for example, bio-inspired engineering of airplanes [3] and censusing of populations of bats [1], [2], [6]. Censusing populations of bats is imperative for quantifying the ecological

Colonies of Brazilian free-tailed bats are of particular interest because they represent some of the largest aggregations of mammals known to mankind. It is challenging to census these bats accurately, since they emerge in large numbers at night from their day-time roosting sites. We have used infrared thermal cameras to record Brazilian free-tailed bats in California, Massachusetts, New Mexico, and Texas, and developed automated image analysis methods that detect, track, and count emerging bats [1].
