Royal Penguins are often confused with Macaroni Penguins (Eudyptes chrysolophus) (Barham & Barham date unknown). In fact, both of these species were at one time considered to be the same species (Kerry and Clippindale 1997). They are the largest of the crested penguins standing about 70 cm in height. Females are usually slightly smaller than males. Both have yellow/orange and black crests that run from their sides all the way to the tops of their heads. The one distinguishing difference between Royal Penguins and Macaroni Penguins is that Royals have white chins and the Macaroni Penguins have black chins (Kerry and Clippindale 1997).
