Abstract: Lay Summary Male guppies reduced their mating preference for an initially preferred female when being watched by an eavesdropping larger conspecific male rival. Such an audience-mediated decrease in mating preference for a particular female was greater when males had previously exhibited a strong initial preference for that female. Males thus pay attention to the phenotype of nearby potential sexual rivals and adjust their mate choice so as to presumably minimize their risk of sperm competition.Twitter: @heatherlauld
