Penguins |
Penguins – their habitat, eating and reproduction
characteristics.
Penguins are birds, they have wings, but
they cannot fly. Instead, they use their wings as flippers to swim in water.
They also paddle with their webbed feet. Penguins are very good swimmers.
Penguins have long, barrel-shaped
bodies. They have short legs and can stand upright. Penguins have dark backs
and white breasts that make them look like men in suits.
Penguins have a funny waddle when
they walk on land. They cannot waddle very fast. When they are on ice or snow,
penguins act like they are sledding. They lie on their stomachs and paddle
forward with their wings. Penguins would rather swim than move about on land.
Penguins habitat
Most penguins live close to
Antarctica, in the southern part of the world. The Adélie penguin and the
emperor penguin live right on the ice of the Antarctic continent. Some penguins
live on the southern coast of New Zealand or nearby islands. A few kinds of
penguins live in warmer regions near the coasts of South America, southern
Africa, and Australia. Penguins in warmer places need to swim in cold ocean
currents to find food.
How Penguins keep themselves warm
Penguins have short, stiff feathers.
The feathers overlap and form a waterproof coat that keeps the birds dry. Some
penguins have another layer of downy feathers for extra warmth. Penguins also
have a thick layer of fat called blubber.
How they eat.
Penguins love seafood and only eat when
they are in the water. They swim near the water’s surface watching for fish,
squid, and crustaceans such as crabs or shrimp. When a penguin spots something
good for dinner, it dives after it.
Scientists have learned that penguins are
fantastic divers. The scientists put special equipment on some penguins. They
measured how deep the penguins dived for food and how long the dive lasted. An
emperor penguin can dive deeper than 1,600 feet (500 meters). That distance is
almost the same as 2.5 city blocks! Some emperor penguin dives can last as long
as 20 minutes. The penguin has to hold its breath the entire time.
Penguins take flying leaps out of
the water to breathe. These leaps are called porpoising because a leaping
penguin looks like a porpoise. Sometimes penguins leap to get away from seals,
sea lions, or killer whales. These animals like to eat penguins.
Penguins reproduction.
Male and female penguins form couples
to raise young penguins, some penguin couples stay together for years. When it
is time to breed, the penguins gather on land in groups called colonies. A
colony of penguins can have thousands of birds.
Some penguins build nests and lay
two eggs at a time. The female emperor penguin lays one egg. The male penguin
puts the egg on top of its feet and uses its belly to cover the egg and keep it
warm. Both parents in other penguin species take turns keeping the eggs warm.
Baby chicks that hatch out of the
egg have only a thin layer of down. The parents use their bodies to keep
newborn chicks warm. Later, the chicks form groups while the parents go off to
find food.
Penguin parents feed their chicks
for 20 to 30 days. By that time, the chicks have grown feathers and can find
their own food. In a year or two, they come back to the colony to find mates
and breed. Penguins live as long as 20 years.
Scientific classification: The emperor penguin is a member
of the Spheniscidae family and is classified as Aptenodytes forsteri. Aptenodytes
translates as featherless or unwinged diver, and forsteri is the
surname of German naturalist Johann Reinhold Forster, who traveled with Captain
James Cook on the HMS Resolution from 1772 to 1775.
