Abstract:Greater Prairie-Chicken (Tympanuchus cupido) lek visitation and stability were examined in 1986-1991 on a $301\text{-km}^{2}$ area in northeastern Colorado. Although 39-47 leks were active during any given year, about 23% of leks disappeared between consecutive years. Twenty of 80 leks were active all six years and 26 leks were active only one year. Relatively stable leks appeared to have greater male visitation than unstable leks. In addition, numbers of males visiting stable leks tended to be correlated with density of leks on the study area. Twenty-one radio-marked males were observed on 286 occasions during peak display periods; 95.1% of those observations were on lek sites. Rates of lek visitation were similar for adults and yearlings captured on leks or during winter.
