DUCK FEATURES
Ducks are found throughout the world in a variety of water habitats. Some
ducks live by the sea and dive for fish; others live on small freshwater ponds
and eat microscopic organisms. All ducks however have many similar
features and adaptations used to survive in their watery habitats.   

The bills of ducks are usually long and flat. They use their bills in many
different ways.

Dabbling ducks are filter feeders and strain out various food items such as
seeds, water plants, and small animals.

Diving ducks, normally found in freshwater, swim under the water and
pursue larger food items like fish.

The feathers of ducks are waterproofed by a protective oil that is produced at
the base of the tail and the duck spreads this oil to the rest of the feathers.
This procedure is called preening and this must be done regularly to
straighten and re-oil their feathers.  

In most duck species the males’ feathers are brighter and more colourful.
Male feathers are vivid for a variety of reasons.
•More colourful feathers help males stand out to attract females.
•Males also use brilliant feathers, combined with lots of noise and fluttering,
to distract predators away from females. Females are usually a shade of
brown to help camoflauge (blend) in with ground nests.

Their webbed feet are excellent for paddling and they can streamline their
wings to dive underwater. Ducks are often clumsy on land and due to the fact
that their legs are placed far back on their body. This gives them more power
in the water but results in a unique waddle on land.

Ducks are able to float on top of the water by trapping air within sacs inside
their bodies. When a duck dives underwater, it releases air from the sacs.
