Mottled DucksIntroduction To Florida's Mottled Duck
The mottled duck (Anas fulvigula) is a non-migratory, close relative of the mallard (Anas platyrhynchos). The Florida mottled duck (Anas fulvigula fulvigula), often called the Florida duck or Florida mallard, is a unique subspecies found only in peninsular Florida, residing in both brackish and freshwater marshes. The Florida mottled duck spends its entire life within the state and has inhabited Florida for thousands of years. Therefore, the management and protection of this subspecies is primarily the responsibility of the Florida Fish and Wildlife Conservation Commission (FWC). The long-term well-being of Florida mottled ducks is threatened by crossbreeding with feral, domesticated mallards and the FWC is working hard to combat this problem.
Mottled ducks are large and brown in color but appear very dark when viewed at a distance. Mottled ducks are darker than female mallards, but slightly lighter in color than black ducks. Approximately 40 percent of the mottled duck's diet consists of animal matter such as insects, snails, mollusks, crayfish and small fish. The remainder of its diet is composed of grass seeds, stems, and roots; seeds of other marsh plants; and bayberries.
Florida mottled ducks have an intrinsic, aesthetic value and are highly prized as a game bird. Also they are a defining member of the unique suite of species characteristic of the prairie ecosystem of south Florida.
It will take an effort by not only the FWC, but all Floridians, to ensure the continued existence of the Florida mottled duck.
