To explore animal groups such as zebras or gelada monkeys, Ben Koger, Blair Costelloe, Iain Couzin, and other researchers from the Max Planck Institute of Animal Behavior, the CASCB at the University of Konstanz, and Aarhus University developed a new method for collecting data about animal behaviour and the animals' surrounding natural physical landscape using drones and computer vision. The researchers use imaging drones to record entire groups of animals in natural settings. Behavioural ecologist Blair Costelloe describes the method: "We created an analytical pipeline that lets us take aerial drone footage and extract information about the locations, movement, and behaviour of the animals. We can measure their spatial distribution and their behavioural states and get rich information about their surroundings, including the 3D-structure of the environment."
