There were grouse everywhere in northern MN where I was camping at Bear Head Lake State Park. I was watching a female ruffed grouse when a male pranced in on display. She was apparently less impressed than me as she hopped up into a tree. He pranced around shaking his feathery mane, lifting one leg and then the other. About 15 minutes later another male came in also displaying. They danced around the tree where she was perched, completely oblivious as I watched and walked around them taking pictures.
