Ducks are very flirty!  Drakes will rise up out of the water shaking their tail and head, flick water or play nip (like a grade schooler poking at the girl he likes on the playground!) or swimming with their neck outstretched.  Both males and females will bob their heads up and down at each other to flirt. Females will flatten their bodies on the surface of the water in a mating pose around males to flirt with ones they are interested in.

They can blow bubbles in their water. Sometimes, they stick their bills into water and breathe out, forming bubbles. They do this to clean anything out of their nostrils.

They sleep with one eye open. Duck’s brains are split in half with one half controlling one eye and the other half controlling the other eye.  So it is entirely possible for them to “turn off” half their brain to rest it while the other half remains alert for predators. Ducks will usually only fully rest both halves if they are in a large group where others can be on the look out.

They are nonviolent. They are quite calm in temperament except when incubating eggs or raising a flock. However, fighting may evoke when a new duck is introduced into an established flock. Such fighting does not last for a long time and hardly results serious injury to any.

Mallard ducks were first domesticated in Southeast Asia at least 4000 years ago, during the Neolithic Age, and were also farmed by the Romans in Europe, and the Malays in Asia.

Ducks are omnivores. They feed on small fish and fish eggs, small crustaceans, frogs, salamanders and other amphibians, snails, worms and mollusks, aquatic and land insects, algae and aquatic plants and roots, grass and weeds, seeds and grain, small berries, fruits and nuts. In addition to these nutritious foods, some ducks will also eat sand, gravel, pebbles and small shells to provide grit that aids their digestion. Grit may also provide trace amounts of critical minerals as part of an overall healthy, varied diet.

It is a myth that ducks like bread. Feeding ducks bread can lead to malnutrition and obesity. To add on, it pollutes their waterways.

The production of eggs is affected by daylight. When there is more daylight, the ducks will lay more eggs. To prevent this from happening, farmers use artificial lighting so that the ducks have about 17 hours of light a day to produce eggs efficiently.

Most duck species are monogamous for a breeding season but they do not often mate for life. Instead, they will seek out new mates each year, choosing the healthiest, strongest, best mate who can help them pass on their genes to a new duckling generation.

They are indecisive animals
