What type of nest does a mallard have?

Mallard ducks typically build their nests on the ground, often in tall grass or reeds near water sources. The nest is a shallow depression lined with down feathers, grasses, and other plant materials for insulation and comfort. Females usually select secluded locations to help protect their eggs from predators. After laying 8 to 13 eggs, the female will incubate them for about 28 days until they hatch.
