When males go to the booming grounds, they go about 25 minutes before sunrise. They stay for about 2 to 3 hours. Males do a dance to attract females.
Males stomp their feet as part of the dance.
They also do the flutter jump to show females how big their territory is. Then they stick out their neck feathers and spread out their tail feathers like a fan. If you have never seen a prairie chicken stomp their feet, it's very hilarious. After the females leave the booming grounds, the males walk around and use confrontive crouching to maintain their territories. This means they squat and stare at each other.
