Sexual selection studies normally measure signal strengths, but signal components and sensory processing may interact to create misleading or attention-capturing illusions.  Male great bowerbirds construct and maintain an extended phenotype that creates a forced perspective visual illusion.  I present evidence that the forced perspective created by males facilitates male mating success, whereby males that produce better visual illusions gain more mates than rival males.  I also discuss the possibility that forced perspective may interact with other aspects of male displays, and discuss the wider implications of these findings.
