Our energetic and inquisitive African blackfooted penguins are visitor favorites.

Watch carefully and you might even see them communicating with each other. When penguins flap their wings or bow their heads, they're telling each other how they feel. Throwing their heads back and wings out means "I'm happy." Leaning forward and opening their beaks means "Go away."
