One Smiling Duckling

The mottled duck (Anas fulvigula)[note 1] or mottled mallard is a medium-sized species of dabbling duck. It is intermediate in appearance between the female mallard and the American black duck. It is closely related to those species.
There are two distinct subspecies of the mottled duck. One subspecies, the Gulf Coast mottled duck (A. f. maculosa), lives on the Gulf of Mexico coast between Alabama and Tamaulipas (Mexico); outside the breeding season, individual birds may venture as far south as Veracruz. The other, the Florida mottled duck (A. f. fulvigula), is resident in central and southern Florida and occasionally strays north to Georgia. The same disjunct distribution pattern was also historically found in the local sandhill cranes. Individuals of both subspecies were introduced into South Carolina in the 1970s and 1980s, where the birds of mixed ancestry have greatly expanded in range, extending through the Atlantic coastal plain of Georgia into northeastern Florida.

The adult mottled duck is 17–24 in long from head to tail. Weigh is 30.9–43.8 oz, with a wingspan of 34.3 inches.
It has a dark body, lighter head and neck, orange legs and dark eyes. Both sexes have a shiny green-blue speculum (wing patch), which is not bordered with white as with the mallard. Males and females are similar, but the male's bill is bright yellow, whereas the female's is deep to pale orange, occasionally lined with black splotches around the edges and near the base.

The plumage is darker than in female mallards, especially at the tail, and the bill is yellower. In flight, the lack of a white border to the speculum is a key difference. The American black duck is darker than most mottled ducks, and its wing-patch is more purple than blue. The behaviour and voice are the same as the mallard.

Mottled ducks feed by dabbling in shallow water, and grazing on land. They mainly eat plants, but also some mollusks and aquatic insects. The ducks are fairly common within their restricted range; they are resident all-year round and do not migrate.
