The family of penguins have 18 species.
They lost the ability to fly and their wings turned into paddles which they use
in the water. They are great swimmers and diving specialists.
On land they waddle and look like
waiters with their white front and black back and head. They all look almost
the same but for the variation of beaks, white or yellow marking on their
faces. Some also have eye crests. They differ very much in size. The emperor
penguin is as tall as a child while the blue penguin is the size of a parrot.
Their webbed feet are at the end of their body and it is used like rudders for
steering.
The Southern Hemisphere, in the
ice-cold Antarctic zones, is where most penguins live. The jackass penguin is
the exception. It breeds in Africa and feeds in cool waters at the tip of South
Africa. Also the Galapagos, Magellanic and Humboldt penguins live in the
tropics fed by the cool current from the Antarctic.

They live most of their time at sea
but come ashore at breeding time on isolated coasts which are along the
Antarctic current. These currents are rich in squid, fish, krill and others
which are the penguin's diet.
The penguin’s feathers are perfect to
protect them in those icy cold waters. They are long, thin and turn down
towards the bottom. At the bottom of the feather is a fluffy tuft, this
mat together and give a wind- and waterproof layer. They are feathered from
head to down their legs. The Adelie penguin has even a feathery beak.
Furthermore, a layer of blubber
underneath the coat protects them from the cold as well as when they jump out
of the water and crash-land on the ice or rocks. They are very good at leaping.
The Adelie penguin leaps up to 2m.
ADELIE PENGUIN |
The female has one or two eggs. She
lays it in a scrape on the ground or on pebbles with sticks and bones to
prevent it rolling off. It also keeps it from the ground of melting
ice. In the more northerly area they put the eggs on tussock grass. The eggs
are incubated for 1-2 months. The chicks are ready to leave after 10 weeks. The
king penguins' chicks are ready to leave after 13 months.
The skuas and other predators take
the penguins' eggs and/or attack chicks
EMPEROR PENGUIN |
Emperor penguins are the biggest.
They can weigh up to 16kg. The larger the penguins the better they keep their
body heat. Emperor penguins breed on the coldest of the sea ice and shores
of the Antarctic. In March the adults come ashore and travel to their breeding
grounds. They mate and lay their eggs in complete darkness of Antarctic winter.
The male incubate the eggs on top of
their feet under a fold of skin to prevent it to freeze. The several thousands
of penguins which are there huddle together to preserve their body heat. They
don't while they are on the egg and live off their fat. To preserve their
energy they sit there and huddle together for warmth.
Male emperors do not have a territory
and therefore do not fight with each other. The gentoo, chinstrap and adelie
penguins are territorial. Their huge breeding colonies are very noisy because
they always squabble.
When the female comes ashore with a
peak full of squid to feed the chicks; the male leaves to feed himself. The
female regurgitates the food at first to feed the chicks and later on they both
feed them. The chicks are ready for the open sea in December.
The huge, vicious leopard seal lurks
under the ice edge to get hold of one penguin or two.
Penguins have always fascinated me. Not sure why but I adore them
