The length of non-disrupted copulations videotaped at lek
10/11 ranged from 3 to 7 s (n = 9) versus 4 to 6 s (n = 6) at other leks
Where females can compare white and yellow males simultaneously, the yellow males do a lot better than white males, but only with high numbers of other yellow males independent of lek
size," Uy said.
In 2001, 60 active or previously active leks
were selected and located with assistance of personnel from the Bureau of Land Management and New Mexico Department of Game and Fish.
The results of this study suggest for the first time that variability in spacing of Gryllotalpa major burrows within a lek
may be related to specific botanical attributes of the grasslands in which these leks
During the 1990-92 breeding seasons (last week of March to the third week of April), we observed male sharp-tailed grouse at six leks
, each located less than 75 km from the others.
Beginning in 1985, several active leks
were observed (Smith et al.

Males at three neighboring leks
in southwestern Manitoba, Canada (49 [degrees] 10'N, 100 [degrees] 13'W) were captured in 1986 and 1987 before females regularly visited leks
But, especially when males display together, and females go to the leks
to window shop, they're a huge advantage.
Between 3am and 4am, the males gather at communal lek
sites - the dance arenas of the bird world - and at dawn they perform their mating displays to attract as many females as possible.
Schroeder and Braun (1992) hypothesized that male greater prairie-chickens attending satellite leks
