What’s wrong with this picture? 2

Two species of pack Ice penguins. These penguins are only found in the Antarctic, where there is sea ice. The difference in size between the Emperor (large) and Adelie (small) Penguins. 3

Adelie Penguins in their natural habitat: walking over ice and snow. 4

This is sea ice. Salt water that freezes in the winter and melts in the summer. It is between 10 -20 ft thick. In ice-covered seas are where Adélie penguins live most of their lives. 5

We live here for 2 months. What would you need to live in a tent for two months? 10

Adelie Penguin. Notice the strong beak and complete feather coverage. 11

Why do you think this Adelie Penguin’s feet are pink? Do Adelie Penguins have long or short legs? 12

Penguins appear to have short legs because most of the leg is hidden under the feathers. Here you can see how long they really are. 13

Penguins have the most feathers per square cm than any other bird. Calculate the density. Compare it to a chicken. There is one bare place, the brood patch, which keeps the eggs warm against the penguin’s skin. 14

In November, the males come ashore, gather rocks and build their nests. They must guard the nest at all times to protect their pile of rocks from other males. 15

The female arrives and the pair form a bond with a unique song. Two eggs are laid and the female returns to the sea to feed. 16

Why does the adult hold the egg on its feet? 19

20

Skuas are the main predator of penguin eggs and chicks. 21

22

Notice how the adult holds the hatching chick 23 on its feet.

Penguin chicks learn how to stay warm. 24

As the chicks get older both parents must go collect food. Chicks huddle together to keep warm in a crèche. 27

This chick is just about to molt its chick feathers for adult ones which will keep him warm and dry in the water. 28

Adelie chicks in the process of molting: adult feathers replacing chick feathers. 29

Tagging the birds allows us to follow their lives. The number on the band tells us which colony they were born in, what year they were born, and who they are (a number instead of a 31 name).
