Rockhopper Penguin.Calgary Zoo.
With some very colorful feathers on their heads, it is hard to mistake the Rockhopper Penguin for anything else. These crazy colors that are on feathers in all directions remind many people of the punk rock generation. It is due to this distinction that they are classified as crested penguins. They are the smallest in that category, weighing no more than five pounds when they are adults. Original public domain image from Flickr
