Bowerbirds: Optimization, The Evolution of Aesthetics, and Art
Sophia Brueckner
Native to Australia and Papua New Guinea, bowerbirds’ uniquely curatorial behavior has long fascinated ornithologists and evolutionary biologists, who cannot explain their creative process. Different birds choose and arrange objects in surprisingly different ways. They are often described as the artists of the animal world because their creations are as difficult to understand as those of human artists. Their arrangements demonstrate a sensitivity to scale, composition, texture, and the interaction of color. There is no way to express their process as a step-by-step algorithm or optimization problem. Like human art, their compositions transcend easily measurable metrics like efficiency, quantity, and strength. Bowerbot is a robotic bowerbird that transforms an empty gallery space by arranging colorful objects such as flowers, leaves, and trash. Visitors will offer Bowerbot objects, which it might accept or reject. Using artificial intelligence (AI) trained on photographs of bowerbirds’ elaborate bowers, Bowerbot will learn how male bowerbirds create “artworks” to attract a mate.
