We deploy digital remote cameras (Reconyx, Inc., Holmen, Wisconsin) at as many of our hair-sampling stations as possible, depending on camera availability. Cameras are aimed at the sampling device such that visiting animals will be detected by the sensor and photographed (see Photo Gallery).
Today’s digital remote cameras are capable of capturing thousands of images before the memory card requires changing, thus minimizing the need for revisits. Furthermore, most units can be programmed to record many frames with a single trigger of the sensor, resulting in a series of images that provide a pseudo-video effect when viewed in quick succession. Such pseudo-videos yield valuable insights into animal behavior, and specifically allow us to evaluate how animals interact with detection devices.
Remote cameras can also detect non-target animals that might not be sampled by our hair-snagging devices—including rare species.
