Ducks with Green Heads
Green headed Duck is not just a male Mallard duck with a green head; there are more ducks with green heads that you may have spotted.
Male ducks are called drakes, and they often have a much more colorful appearance than female ducks in northern species. The male will molt after the breeding season and become similar to the female, called the eclipse plumage.
This will happen after nesting, and then they will molt again to get their breeding colors in the winter.
Ducks have such colorful and interesting patterns and shapes. Even ducks’ feet can be bright orange or blue.
These ducks with green heads migrate and spend the summer breeding further north, like in Canada, and the winters further south. All except the Mallard, which does not usually migrate.
So if you don’t know what that duck with a green head is, take a look at this guide and find out.
How to identify dabbling ducks
What are dabbling ducks? Ducks can be split into two broad groups: dabblers and divers. As the name suggests, diving ducks feed mainly by diving underwater, using their strong feet (and sometimes their wings) to swim. Dabbling ducks, however, feed predominantly at the surface, sometimes even grazing on land. Many dabblers can often be seen upending, with their heads underwater and bums in the air.
Let’s look at seven different ducks that have greenheads below:
Mallard
Mallards are large ducks with green heads on the males. They have bright yellow bills and gray bodies with brown breasts and black towards the tail. They have a curl of tail feathers and a blue patch on the wings bordered with white which is called a speculum.
Mallard is a very adaptable species, being able to live and even thrive in urban areas, which may have supported more localized, sensitive species of waterfowl before development.
The mallard was one of the many bird species originally described in the 1758 10th edition of Systema Naturae. They frequently interbreed with their closest relatives in the genus, such as the Anas.
Genetic analysis has shown that certain mallards appear closer to their Indo-Pacific relatives, while others are related to their American relatives. Mitochondrial DNA data for the D-loop sequence suggest that mallards may have evolved in the general area of Siberia.
Mallard bones rather abruptly appear in food remains of ancient humans and other deposits of fossil bones in Europe, without a good candidate for a local predecessor species.
Mallards are differentiated in their mitochondrial DNA between North American and Eurasian populations, but the nuclear genome displays a notable lack of genetic structure.
The mallard is the most common duck in the United States, with the greatest abundance between the Appalachian and Rocky mountains.
Both sexes have an area of white-bordered black, or iridescent blue feathers called a speculum on their wings; males especially tend to have blue speculum feathers.
Females and juveniles are mottled dark brown with orange bills, but they still have the blue speculum. Upon hatching, the plumage of the duckling is yellow on the underside and face (with streaks by the eyes) and black on the back (with some yellow spots) all the way to the top and back of the head. Several species of duck have brown-plumaged females that can be confused with the female mallard.
Mallards dabble to feed on seeds, rootlets, and tubers of aquatic plants off swamp and river bottoms.
Scientific Name: Anas platyrhynchos
Length: 19.7-25.6 in (50-65 cm)
Weight: 35.3-45.9 oz (1000-1300 g)
Wingspan: 32.3-37.4 in (82-95 cm)
Mallards remain all year in most of the lower 48 and the western coast of Canada and Alaska. While Mallards were originally restricted to North America and the central parts of Eurasia, humans have introduced them to every continent except Antarctica for hunting and agricultural purposes.
Mallards are one of the most commonly spotted and recognizable ducks that will happily be fed on ponds and rivers. They are dabbling ducks that feed on the water plants and do not dive.
