It uses wings by jumping up and down to make wind blowing dry leaves floating away in order to keep its own display ground "tidy and clean", for courtship display to females that became interested by calls and paid visit to the lek.

Thanks to Daeng@Krung Ching park ranger who discovered the leks and maintain the safe condition to the birds from hunting pressure.
