The effects of predator size and female receptivity on the courtship behavior of captivebred male guppies (Poecilia reticulata) were investigated. Male guppies exhibited riskreckless courtship behavior in that they did not decrease the amount of time spent performing visually conspicuous sigmoid displays and increase the frequency of attempted forced copulations when large predatory fish were present. Female receptivity (i.e., virgin or non-virgin females) also had no effect on male courtship behavior.
