Hyla
In some Hyla frogs, the male frogs fight and compete. Male H. versicolor frogs show up where the females like to go. This behavior, called lekking, is common in many species of Hyla. In order to sing clearly, the males need to be a certain distance apart from each other. When one male gets too close to another male's singing place, the two males may fight or do something else that is like fighting. Male H. versicolor sometimes show off to each other before they fight, so they can see whether they are likely to win first.
