A fundamental challenge in behavioral ecology is the collection of high-quality datasets on animal spatiotemporal positions. Recent innovations in tracking technology have made it possible to collect the quantitative data on movement and behavior of animals such as mammals, birds, fishes and insects. Particularly, an automated video tracking system using barcode tags to track all individuals enables us to decipher the spatial and temporal interactions between individuals in social insect colony. In our talk, we will review recent studies using tag-based tracking and then introduce our tracking setup for ant colony using Bug tag (Robiotec Inc.). Using this data, we address how ant rhythmic behaviors are organized by various social interactions. At the end, we will discuss the impacts of the tracking technologies on the studies of animal behavior and ecology.
