Continuing the series on Fractal arts. Selected the theme on birds as they have a beautiful and vibrant natural pattern which I have recreated using a form of algorithmic art obtained by calculating fractal objects based on parameters of generative art and evaluation of the resulting image. This series is an interpretation of how fractal art blends with natural patterns we see around us. "Sentinel Owl" seventh one in this series is a fractal art representing this nocturnal bird of prey whose broad head, binocular vision, binaural hearing, sharp talons and feathers adapted for silent flight makes it wisest guard among the bird species.
