It is used to attract females to the lek, and less often after females have arrived at the lek. Displaying males also cluck (also made by females), bark, make a sound like a popping cork, gobble, and whine.Our objective was to evaluate the efficacy of aerial infrared (AIR) technology for estimating abundance of prairie grouse by comparing AIR lek counts with ground-based lek counts of Columbian sharp-tailed grouse T.
