There are not exclusive names for the female penguin, but they have been called hens. Most of the time they are simply referred to as the female penguin.
Penguins primarily communicate vocally, but they also communicate through body language and posturing. Penguins all look virtually identical, which makes individual recognition very difficult. To overcome this, penguins have evolved different sounding voices and the ability to recognize the individual voices of their mates or chicks. This allows the birds to recognize and find their important conspecifics amid the masses, which all look the same.
According to Falklands Conservation, penguins can swim at speeds of up to 17 mph; however, they normally average between 9 and 15 mph. Penguins can also dive further and swim faster than any other bird.
