Mallards: (Anas platyrhynchos)

Their courtship starts in the fall, and by midwinter pairs have formed. Mated pairs migrate northward together, heading for the female's place of origin. The male stays with the female until incubation is well underway, then leaves to join a flock of other males to begin the annual molt. Normally shy, Mallards become tame in city parks and on reservoirs, where they can fed by hand, they often interbreed with domestic ducks and produce a variety of odd-looking hybrids. They feed on seeds and insects from the water surface, diving for water-weeds and sunken acorns, grazing on land-grasses, plant roots and seeds and shaking invertebrates from among the foliage.
