Prairie chickens use the same leks each year.
Another term for leks is "booming grounds." The male emits a "booming" sound while strutting around his territory. On a calm day, this characteristic booming may be heard a mile away.
Since 1900, the total number of lesser prairie-chickens has decreased by an estimated 97 percent. Conversion of habitat to cropland was the primary culprit, though market hunting, brush control and overgrazing were contributing factors. Attempts to establish new populations have failed.
