Here males occasionally crowd around a perched female; they make no effort to defend an exclusive mating territory but instead attempt to copulate by displacing rivals from the female. In this work we describe this spatial-nuptial system, which entails site fidelity without territoriality, unisexual swarms, common patrol routes, collective sexual approaches, and "scramble competition polygyny.” Mating success is evaluated in relation to the familiarity with flight paths ("routine patrollers” versus "newcomers”), to the type of sexual approach ("single” males versus "in- group” males), and, in the laboratory, to the individual activity level.
