Similarly, Doubleup Ducks, a creation of Eyecon, brings the same feeling again through a collection of loveable toys. The slot is made up of items you would naturally find at the fair. With a simple pale blue background, Doubleup Ducks consists in vibrant reels and symbols. Let’s revive our childhood by checking this game out. A very familiar looking elephant, who just happens to be pink, is Wild and substitutes for all symbols (except the Duck Shooter) and doubles the prize when it appears on a winning line. With a double or nothing Gamble feature and line wins up to a staggering x 95000 for five of those fluffy pink elephants, you’d have to be quackers not to.

The mottled duck (Anas fulvigula)[note 1] or mottled mallard is a medium-sized 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 considered a subspecies of the former, but this is inappropriate (see Systematics below).

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.[2][3]

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.


In Florida, U.S.

The adult mottled duck is 44 to 61 cm (17–24 in) long from head to tail. 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. The breeding habitat is coastal marshes. The nest is built on the ground amongst vegetation, such as bull-rush and marsh grass.


  • Male:
    • Length: 19.7-22.5 in (50-57.2 cm)
    • Weight: 30.9-43.8 oz (876-1241 g)
    • Wingspan: 32.7-34.3 in (83.1-87.2 cm)
  • Female:
    • Length: 18.5-21.0 in (46.9-53.4 cm)
    • Weight: 24.7-40.6 oz (699-1151 g)
    • Wingspan: 31.5-327.2 in (80-83.1 cm)


The Floridian population, which occurs approximately south of Tampa, is separated as the nominate subspeciesAnas fulvigula fulvigula and is occasionally called the Florida mottled duck or Florida mallard. It differs from the other subspecies, the Gulf Coast mottled duck (A. f. maculosa) (etymology: maculosa, Latin for 'the mottled one'), by being somewhat lighter in color and less heavily marked; while both subspecies are intermediate between female mallards and American black ducks, the Florida mottled duck is closer to the former and the Gulf Coast mottled duck closer to the latter in appearance; this is mainly recognizable in the lighter head being quite clearly separated from the darker breast in Gulf Coast mottled ducks, but much less so in Florida mottled ducks. As the subspecies' ranges do not overlap, these birds can only be confused with female mallards and American black ducks however; particularly female American black ducks are often only reliably separable by their dark purple speculum from mottled ducks in the field.

mtDNA control regionsequence data indicates that these birds are derived from ancestral American black ducks, being far more distantly related to the mallard, and that the two subspecies, as a consequence of their rather limited range and sedentary habits, are genetically well distinct already.[5]

The Florida mottled duck (A. f. fulvigula)

As in all members of the 'mallardine' clade of ducks, they are able to produce fertile hybrids with their close relatives, the American black duck and the mallard. This has always been so to a limited extent; individuals of the migratory American black ducks which winter in the mottled duck's range may occasionally stay there and mate with the resident species, and for the mallard, which colonized North America later, the same holds true.[5] Genetic tools have been developed in order to robustly classify hybrids and to assess and monitor the genetic dynamics of introgression between the Florida mottled duck and the mallard.[6]

While the resultant gene flow is no cause for immediate concern,[note 2]habitat destruction and excessive hunting could eventually reduce this species to the point where the hybridization with mallards would threaten to make it disappear as a distinct taxon.[7] This especially applies to the Florida mottled duck,[8] in the fairly small range of which rampant habitat destruction due to urbanization and draining of wetlands has taken place in the last decades; this, in combination with climate change affecting the Everglades, could be sufficient to cause the Florida mottled duck to decline to a point where hunting would have to be restricted or prohibited.[5] At present, these birds too appear to be holding their own, with a population of 50,000-70,000 individuals. While hybridization is common, double white bars above and below the speculum are not a sufficient indicator of hybridization and therefore should not be used to determine genetics.[1]
