Mallard Nest and Eggs

Remarkably adaptable to civilization, the mallard—the most common duck in the world—will nest in a city park if there is even a small pond. This species usually nests near the water’s edge, but occasionally chooses a site on higher ground.

The mallard’s nest is built on the ground among dead grasses or reeds, often close to water. It can accommodate up to 13 light-colored eggs. To attract nesting mallards, plant hedges and shrubs near water.
