The Rockhopper Penguins are three closely related taxa of crested penguins that have been traditionally treated as a single species and are sometimes.
They are excellent swimmers thanks to the design of their flippers. They form very large colonies. Social interaction is very common, especially among the young. The chicks form crèches to keep warm and stay protected. The Macaroni Penguins seem to get along very well. They are less aggressive than other types. However, they can be very protective of their young and the females are known to fight aggressively for the attention of certain males that they would like to mate with.
