British scientist and lens-based artist Kathryn Cooper explores concepts of deconstructed movement to reveal the self-organised nature of bird flocks. Seemingly coordinated collective behaviour emerges from simple local interactions between individuals. It is a concept that challenges our notion of leadership, and provides a model for how patterns arise in other complex systems, including our own societies. Her work also considers the starling roost in Ripon, North Yorkshire, thinking a lot about how the paths that the flock trace appear to look fluid and ocean-like, engulfing the senses and revealing a nightly dance essential to survival, drawing parallels between avian dynamics and human systems of influence, direction and collective behaviour.
