Male's Display :
A male puffs out the white rump geathers "to form a remarkable white ball, then bows, droops vibrating wings, and spreads tail. He makes short 'butterfly' flights with the puff expanded, and may drop vertically through the air with raised wings. Courting birds audibly click their wings" (Zimmerman et al 1996).
