Greater sage-grouse disperse to areas surrounding the leks for nesting. Males congregate in leks (display arenas for visiting females). The males are polygamous, and perform courtship displays in leks. Males from traditional territories and leks have different courtship strategies. Males of "V. maculifrons" tend to form loose aggregations, resembling leks, during mating. Males often gather in loose leks, where they sing to attract females. Males display at regularly used sites, each male utilizing several dispersed leks or display areas. Courtship is often facilitated through forming groups, called leks, in flies and many other insects. As females rarely mate outside of leks, it is advantageous for males to form leks. Males gather in leks to court, usually in late February to April. Neighboring males in leks do the same thing when they encounter their borders. There have been several hypotheses proposed as to why males cluster into leks. The leks themselves do not contain resources for the females. Males select hilltops, ridges, or any place with a good field of view for leks. Another way males get to mate with several females is through the use of leks.
