Ducks
are birds. They are also called "waterfowls" because they
are normally found in places with water like ponds, streams
and rivers. They are related to geese and swans. The duck
is the smallest of them all. Ducks also have shorter necks
and wings and a stout body. They can live from 2-12 years,
depending on species.
Ducks
have webbed feet, designed for swimming. Their webbed
feet act like paddles for the ducks. A duck waddles instead
of walk because of its webbed feet. Do you know that the
duck's feet cannot feel cold even if it swims in icy cold
water ? Well, the reason for this is because its feet
has no nerves or blood vessels.
Another
special thing that the duck has is its water-proof feathers.
There is a special gland that produces oil near the duck's
tail which spreads and covers the outer coat of the duck's
feathers, making it water-proof. Beneath the water-proof
coat are fluffy and soft feathers to keep the duck warm.
Ducks
keep clean by preening themselves. They do this by putting
their heads in funny positions and putting their beaks
into their body. They preen themselves very often.
