The breeding and mating behavior is quite elaborate with the male sitting on his hocks, moving his wings up and down while throwing his head from side to side. During this time the male will usually make a thumping sound and will inflate his neck area and create a loud booming noise. The receptive female walks with her head down, popping her beak and shaking her wings ("clucking"). When approached, the female will sit, allowing the male to mount from the back.
