No its not a gentoo penguin in fancy dress!, this is a different type altogether. Named macaronis after some 18th century English travelers called "Macaroni Dandies" who took on some of the more flamboyant European fashions. Macaroni penguins with their bright yellow crest feathers nest on Antarctic islands, in greatest numbers on South Georgia and Heard Island. They are about 4.2kg in weight and some 70cm tall, superficially they are similar to the smaller rockhopper penguins that they are frequently found nesting nearby.
