The mottled duck (Anas fulvigula) is a species of dabbling duck found in Australia and New Zealand. The male and female mottled ducks exhibit distinct physical differences, particularly in their plumage and size.
Male mottled ducks have a distinctive plumage pattern, with a dark brown head and neck, a white breast and belly, and mottled brown and white flanks. They also have a bright yellow bill and feet. Female mottled ducks, on the other hand, have a more subdued plumage, with a brown head and neck, a white breast and belly, and brown flanks. Their bill and feet are also a duller yellow.
In addition to their plumage differences, male and female mottled ducks also differ in size. Males are typically larger than females, with an average weight of 600-700 grams compared to 400-500 grams for females.
The distinct physical differences between male and female mottled ducks are likely due to sexual selection. The bright plumage and larger size of males may make them more attractive to females, and thus increase their chances of mating.

Sexual selection
Sexual selection is a key factor in the evolution of many species, including mottled ducks. It is a form of natural selection in which individuals with certain traits are more likely to mate and produce offspring than individuals without those traits. These traits can be physical, such as bright plumage or large size, or they can be behavioral, such as elaborate courtship displays.
-
Plumage
In mottled ducks, males have brighter and more contrasting plumage than females. This is likely due to sexual selection, as males with brighter plumage are more attractive to females and thus have a greater chance of mating.
-
Size
Male mottled ducks are also larger than females. This is also likely due to sexual selection, as larger males are more attractive to females and thus have a greater chance of mating.
-
Courtship behavior
Male mottled ducks also engage in elaborate courtship displays to attract females. These displays include head bobbing, neck stretching, and wing flapping. These displays are likely to have evolved through sexual selection, as they help males to attract females and thus increase their chances of mating.
Sexual selection is a powerful force that has shaped the evolution of mottled ducks and many other species. It has led to the development of a variety of traits that help individuals to attract mates and produce offspring.
Habitat
