They do make noise though and can be heard making a variety of grunts, whistles and even yodels. Ducks are omnivores so feed on a variety of plants and animals. Diet depends on a range of factors including species and habitat. For example, dabbling Ducks the tipping Ducks tend to feed on plants and insects, while diving Ducks, which are better suited for deeper water, favour fish and crustaceans.
In the UK, feeding ducks bread is a popular activity, but not one that you should take up. Bread is actually bad for ducks — read about why in our blog post. While we see them mostly in the water, Ducks are excellent flyers. Every year, during the autumn months, they migrate to warmer countries.
As you might imagine, finding such food requires superb diving skills. Indeed, sea ducks are among the most accomplished divers of all waterfowl, with some reportedly diving to depths of feet. Perhaps the best way to understand how sea duck life history differs from that of other ducks is to contrast them with the familiar mallard.
Of course, there is the obvious difference—mallards spend their winters on land and not at sea. Mallards typically breed during their first year.
They also rely on seasonal wetlands, which may dry up during some years, and mallards are, therefore, well adapted to moving into new areas when habitat conditions change from one year to the next.
Mallards generally breed each year and they lay fairly large clutches of nine to 12 eggs. Their nest success is low, but duckling survival is moderate, with mallards relying on multiple nests renesting in the event of failed nesting attempts each year to increase their chances of hatching ducklings. They typically live to be about 2 years old. In contrast, sea ducks have delayed maturity, breeding for their first time at two to three years of age or even older.
Sea ducks typically rely on stable environments with predictable food resources during the breeding season. This allows the warm blood going from the body into the feet to warm the cooler blood re-entering the body from the feet, and the blood going to the feet is cooled enough that the cold does not bother the duck.
All birds have this circulatory system in their legs and feet. A duck has water-proof feathers. This tiny gland produces oil which the duck uses to coat its feathers.
The duck picks up the oil with its head and beak, and then smears it all over its body to make the outer feathers waterproof. Without this protective barrier, a ducks feathers would become water-logged and because they spend their whole lives around and in water, this water-proof barrier is extremely important. Beneath the water-proof coat are fluffy and soft feathers which keep the duck warm.
The ducks mouth is called a beak or bill. The lamellae helps the duck to grip its food so that it will not slip off. However, ducks beak comes in different shapes and sizes.
The shape of the beak and body determines how the duck will hunt for its food. Ducks keep clean by preening themselves. Ducks do this by putting their heads in funny positions and putting their beaks into their body.
Ducks preen themselves very often. Preening also removes parasites, removes scales which cover newly sprouting feathers and also involves the removal of spreading oil over clean feathers. Many species of duck are temporarily flightless while moulting. Ducks seek out protected habitats with a good food supply during this period.
They usually moult before migrating. Ducks are found in wetlands, marshes, ponds, rivers, lakes and oceans. This is because ducks love the water. Some species of ducks migrate or travel longs distances every year to breed. Ducks usually travel to warmer areas or where the water does not freeze so that they can rest and raise their young. The distance may be thousands of miles away.
