Mate choice on leks.

In lek-breeding animals, males defend tiny territories clustered into arenas, where females come to mate. Typically, most lek males secure relatively few copulations while a small number are highly successful. Recent studies suggest that the skewed distribution of matings seen at leks may be the result of females using a variety of criteria to select particular mating partners. Nevertheless, the possible benefits to females of mate choice at leks, where males offer neither resources nor paternal care, remain obscure.
