Ducks are waterfowl popular for their typical way of walking, called waddling. This is because the legs are placed in the backward direction. The male and female members of this species are called drakes and hens respectively. They differ in the amount of plumage they can show while mating. They also have a distinct and different call. Indiscreet terms, the term duck refers to the female member of the species while the males are called drakes.
Females lay many eggs on two occasions in a year. The eggs, feathers and meat of ducks are considered to be precious. These aquatic birds are hunted for these. They are found in freshwater as well as in sea water. Ducks are monogamous when it comes to selecting partners. Most species mate just once a year and lay their eggs in nests. The mother duck is known to take care of her offsprings. It leads them to the water for their first plunge.
Quite contrary to popular belief, ducks don't 'quack'. Instead, they are known to indulge in whistling, yodeling and grunting.
Ducks have quite a few enemies. Ducklings are unable to fly, and this makes them all the more vulnerable to attack by predators. They have predators in the water in the form of large fishes as pike, crocodiles, and herons. Their nests are also vulnerable to attacks from foxes and birds like hawks and owls. Falcons are known to be able to get to ducks despite their ability to fly at a fast speed.
