As I said, in my humble opinion, they are the greatest bird ever to walk the earth. Collecting penguins is a current hobby of mine. I collect anything having to do with penguins . Some may have a crest and long feathers on their sides. There are some that have brightly colored feathers on their necks.
Penguins have about seventy feathers per square inch.
Penguins have special oil that they spread over their bodies. This makes their bodies water-repellent. Penguins that live in warm climates have pink skin on their faces, legs and feet. This is to help them cool down. There are not one but no fewer than 17 species of penguins , of which only four breed on the Antarctic continent itself.
