The
Mottled Duck is a bird of the Gulf Coast in the U.S., found from Florida to
Texas. While they have close relatives in the
Mallard and the American Black
Duck, the Mottled Duck is the only "typical" dabbling duck that summers
and breeds in the far South. Historically, populations were
geographically distinct from the closely related Mallard. However,
with domestication of the Mallard, large numbers of Mallard now also
oversummer in the South, leading to breeding between Mottled Duck and
Mallard populations. Genetically distinct Mottled Ducks are thus
become less common, especially in Florida where Mallard populations are high
in the summer.
Habitat: Found in open marshy habitats, typically ponds, lakes, or marshes with extensive surrounding vegetation. Prefers wet habitats without trees.
Diet: Omnivorous, feeding on a variety of plant and animal matter, including seed and roots of aquatic plants, aquatic and terrestrial insects and their larvae, small mollusks and crustaceans, and occasionally small fish.
Behavior: Forages as do other dabbling ducks, swimming in shallow water and dabbling just below the water's surface with their bill.
Nesting: The nest of a Mottled Duck is a bowl of wetland vegetation and grasses, typically built in wetland vegetation or grassland surrounding a water body. The female alone incubates the eggs and tends to the young after hatching, but the young find their own food.
Song: Quacking typical of the genus
Migration: Considered a permanent resident throughout its range. However, there are some short local movements in response to habitat conditions, and some birds on the western Gulf Coast may move southward into Mexico for the winter.
