Seasonal Lekking Behavior of the Greater Prairie-Chicken in Illinois
Spring behavior of prairie-chickens (Tympanuchus cupido) has been studied extensively, however there is little information on fall-winter lekking activity. Greater prairie-chickens were observed weekly on a lek from 25 September 1982 to 23 June 1983 during morning and evening hours in Jasper County,...
