Story of Penguins:
Penguins are
flightless seabirds that live almost exclusively in the Southern Hemisphere.
They are built for swimming, with sleek black-and-white plumage, dense
feathers, and strong flippers. They range from the tiny blue penguin, at about
12 inches, to the massive emperor penguin, which stands over 3 feet tall.
How have
penguins adapted to life in cold Antarctic waters?
Penguins are
built for the freeze. They have thick, waterproof feathers and a layer of
blubber that traps heat, along with solid bones and stiff flippers for diving.
They also huddle together to reduce heat loss by as much as half.
Life is not
always easy for penguins.
**Singing: **
Adults sing to their mates, and chicks sing for their parents.
**Sledging: **
Penguins speed down icy hills on their feet and bellies to get somewhere fast.
Penguins go
surfing, too. They surf through the waves, and sometimes they surf right from
the water up onto the land. A penguin that surfs is called a “hang-ten-guin.”
They swim,
they march, and they slide through the snow. They are penguins, and they are
perfectly suited to life at sea. They have a sleek shape for speed, and a layer
of blubber keeps them warm. Their stiff flippers act like boat paddles to push
and steer, and their big eyes help them see underwater. Their black backs make
them hard to see from above, while their light bellies make them hard to see
from below. But it is their strong, solid flippers that help them escape
predators and get where they want to go.
Penguins can
swim about 15 miles an hour. When they want to go faster, they leap out of the
water as they swim. This is called porpoising, because it is what porpoises do.
A predator is
an animal that eats other animals.
Penguins’
favorite food? Life in the ocean is fish-elicious! Penguins eat a lot of fish.
They have a hooked bill, or beak, to help them grab their dinner, and barbs on
their tongues and in their throats help them hold on to slippery food.
They drink
salty water to go with that fish. Penguins are able to remove the salt from
ocean water, leaving them fresh water to drink while the salt dribbles back
into the ocean.
While penguins
are swallowing their dinners, they must be careful not to end up as dinner
themselves. Penguins are a favourite food of marine mammals such as leopard
seals and killer whales.
Most penguins
lay two eggs at a time, but often only one egg survives. The mother and father
take turns keeping the egg warm. In many cases, the parents keep the chick warm
and fed. After a couple of weeks, hundreds or even thousands of chicks wait
together while the parents go back to the sea to find food. As the chicks wait,
they are in constant danger from skuas, eagles, and other animals. Finally, the
parents return with food, but they must find their chicks in a huge crowd of
baby birds. How do they do it? The baby birds sing special songs to help their
parents find them.
In a few
months, the whole family returns to the sea. For emperor penguins, getting to
their nesting grounds is hard work. Their home is Antarctica, the coldest place
on Earth.
Emperor
penguins nest much farther from the ocean than other penguins do. They must
march for days and nights through snow and wind. After laying her egg, the
female gives it to the male, who keeps it warm in a flap under his belly.
Unlike other penguins, the male emperor cares for the egg by himself while the
female goes back to the ocean to find food. The mother has been gone for more
than four months. The father clusters with other male penguins to keep himself
and his eggs safe and warm. During this time, the father eats nothing but snow.
When the mother returns in July, the father quickly goes to the ocean to find
food. By December, the whole family is ready to go.
