    Mottled Duck

The Mottled Duck (Anas fulvigula[1]) or Mottled Mallard is a medium-sized dabbling duck. It is intermediate in appearance between female Mallard and American Black Duck. It is closely related to those species, and is sometimes considered a subspecies of the former, but this is inappropriate (see below). The conservation status of a species is an indicator of the likelihood of that species continuing to survive either in the present day or the future. ...

There are two distinct populations of Mottled Ducks.

The adult Mottled Duck is 55cm long. 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. Male and female are similar, but the male's bill is bright yellow, whereas the female's has a greenish yellow hue. A mallard hen. ...

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 Mottled Ducks, and has a bluer wing patch. The behaviour and voice are the same as for Mallard. Binomial name Anas rubripes Brewster, 1902 The American Black Duck (Anas rubripes) is a medium-sized dabbling duck. ...


Mottled Ducks feed by dabbling in shallow water, and grazing on land. They mainly eat plants, but also some molluscs and aquatic insects. This duck is fairly common within its 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. Flock of Barnacle Geese during autumn migration Many species of birds undertake seasonal journeys of various lengths, a phenomenon known as Bird migration. ...


Systematics

The Floridan population, which occurs approximately south of Tampa, is separated as the nominate subspecies Anas fulvigula fulvigula and is occasionally called the Florida Duck or Florida Mallard.[2]) 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 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 Mottled, 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.

Wikipedia does not have an article with this exact name. ...


mtDNA control region sequence data indicates that these birds are derived from ancestral American Black Ducks, being far more distantly related to the Mallard, and that the subspecies, as a consequence of their rather limited range and sedentary habits, are genetically well distinct already (McCracken et al. 2001). Mitochondrial DNA (mtDNA) is DNA which is not located in the nucleus of the cell but in the mitochondria. ... part of a DNA sequence A DNA sequence (sometimes genetic sequence) is a succession of letters representing the primary structure of a real or hypothetical DNA molecule or strand, The possible letters are A, C, G, and T, representing the four nucleotide subunits of a DNA strand (adenine, cytosine, guanine...


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 (McCracken et al. 2001). A clade is a term belonging to the discipline of cladistics. ... // In biology, hybrid has two meanings. ... World map showing North America A satellite composite image of North America. ...


While the resultant gene flow is presently no cause for concern,[3] 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 (Rhymer & Simberloff 1996). This especially applies to the Florida Duck (Mazourek & Gray 1994), 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 Duck to decline to a point where hunting would have to be restricted or prohibited (McCracken et al. 2001). At present, these birds too appear to be holding their own with a population of 50.000-70.000 individuals (BirdLife International 2004). Gene flow (also known as gene migration) is the transfer of genes from one population to another. ...
