3. Location Live in the Southern Hemisphere Abundant on temperate and sub-antarctic islands Live in areas where their inability to fly is not detrimental to their survival (not many land predators)

4. Characteristics: Aquatic, flightless birds Highly adapted to life in the water Countershading: a form of camouflage that helps keep them safe in the water (they look like they are wearing a tuxedo)

5. Size: Emperor Penguin = largest – 3.7 feet tall, 60-90 pounds Fairy (Little Blue) Penguin = smallest – 16 inches tall, 2.2 pounds

6. Population Species with the highest population is the Macaroni Penguin (23,308,000) Species with the lowest population is the endangered Galapagos Penguin with only between 6,000-15,000 left

8. Galapagos Penguin

9. Behavior Can spend up to 75% of their lives in the water Do all of their hunting in the water Catch prey in their beaks and swallow it whole Some only leave water for molting and breeding

10. Diet Krill Squid Fishes

11. Hunting and Collecting Food Feed at sea Find food within 50-60 feet from the surface, so they do not need to dive very deep Rely on their vision while hunting

12. Fasting During breeding season, penguins fast Fun Fact: Male emperor penguins may fast 90 – 120 days during courtship, breeding, and incubation of the eggs

13. Reproduction Each penguin has a distinct call, allowing individual penguins to find their mate and their chicks in large groups Most breed during spring and summer King and Emperor penguins lay only one egg –all other species lay two eggs Eggs take between 1 month and 66 days to develop and hatch, depending on the species

14. Flippers and Feathers Instead of wings, penguins have paddle-like flippers Each flipper is covered with short, scale-like feathers Flippers used to propel Penguins through water

15. Flippers and Feathers

16. Why are the feathers still there?

17. Feathers help keep water away from the skin Penguin feathers are highly specialized: short, broad, closely spaced

18. Penguins lose their feathers once per year, a process called MOLTING

19. Movement Swim quickly because if their flippers and webbed feet Walk slowly using short steps or hops When traveling on ice, Antarctic penguins often use toboggan on their bellies –use flippers and feet to slide their bodies forward along the ice
