We know that animals have evolved a variety of patterns to manipulate the perceptions of their predators to afford themselves a modicum of safety. Greater Bower birds utilize ____________________ in the mating domain. Males construct a bower; its function is to provide an arena in which males display to females standing in an avenue that leads up to the bower. The males decorate the avenue with a variety of objects, such as stones and shells. But they do not do so in a chaotic manner. The larger objects are placed closer to the bower and the smaller objects farther away. This creates a forced perspective the opposite of the Cinderella Castle; the bower appears smaller than it actually is. Endler and his colleagues suggested that the male courting in the bower now appears larger and thus more attractive to the female. Data on male mating success collected in the wild supports their hypothesis.
