Penguins have a hard time getting out of the way of their predators espcially since they are one of the largest groups of flightless birds. They walk standing straight up and looking quite dignified. Penguins spend a great deal of their time swimming and waddling. We typically think of penguins as being black and white and looking the same but their looks vary according to which species they belong to. Each species may be identified by its members according to a distinct and unique head marking or headband.
Penguins keep warm with layers of insulation.
They also huddle togehter in groups to keep warm. Finally, penguins communicate via sound and body language. Each species has a distinct voice. They also use body movements such as staring, bowing, paddling, pecking, bumping, and crouching. I will also leave another website about the Emperor Penguin and other penguins of Antarctica.
