What’s wrong with this picture?

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.

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.

18
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
25
26
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.

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).
32
Adelie chicks getting ready to swim for the first time.

Hungry Adelie Penguins returning to the sea for
food.
