The mottled duck (Anas fulvigula) 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, and is sometimes erroneously considered a subspecies of the former.
Along the Gulf of Mexico coast, the mottled duck is one of the most frequently banded waterfowl. This is due in part to the fact that it is mostly non-migratory. Approximately one out of every 20 mottled ducks is banded, making it an extremely prized and sought after bird among hunters.
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...

Rare
Under 5% of wildlife watchers report a Mottled Duck sighting in Big Cypress National Preserve on a given day, based on 54 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 109th most-seen of the 199 birds we can rate there. Over three days the chance rises to about 10%, if each day is a fresh chance.
June
In that month about 10% of wildlife watchers report a Mottled Duck in Big Cypress National Preserve on a given day, against under 5% in July to May, the lowest months. That is one of Big Cypress National Preserve's wettest months, with about 260 mm of rain against 40 mm in March.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Mottled Duck sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
3rd of 4
Of the 4 parks where we can rate Mottled Duck sightings, Big Cypress National Preserve ranks 3rd at under 5%. The best odds are in Merritt Island National Wildlife Refuge (United States, about 30%) and Padre Island National Seashore (United States, about 20%).
GBIF citizen-science records
It is estimated from how often the Mottled Duck is recorded against all the birds logged in Big Cypress National Preserve (54 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
