James D's Penguins facts

I found these interesting facts :

• Penguins are birds that cannot fly.
• They are great swimmers and divers.
• Their wings work as paddle for swimming.
• The torpedo shape of their body helps them swim at high speeds.
• They can also waddle on land.
• Penguins have two eggs.
• They are born with a gland closer to their breaks.
• When they saltwater, water passes by and salt is stored in the glands.
• When the salt storage completely fills the gland, penguins go to a rock and knock his beak.
• This allows him to empty the salt content.
• Male penguins take care of their chicks.
• Parents take turns warming the egg.
• Female penguins go for searching foods.
• In cold places, males balance eggs on their feet and cover with belly flap to keep them warm.
