Use the following information for the next 5 questions (until you see a solid line): In some species of the grouse family of birds, males display to females in a large group called a lek. During the mating season males compete among themselves, with the most successful males securing positions located near the center of the lek, and less successful males being restricted to the periphery of the lek.
