Another name for the ring-necked duck is the black-jack duck. This alternative name is derived from the bird’s distinctive black plumage and its habit of diving underwater to feed. The black-jack duck is a small to medium-sized diving duck, with males and females having different plumage characteristics.
In terms of appearance, the male ring-necked duck is strikingly beautiful. Its head and neck are black, while its body is a rich brown color. The most distinctive feature, which gives the bird its name, is a faint chestnut-colored ring around its neck. However, this ring is often difficult to see, especially at a distance. Hence, the name “ring-necked” can be misleading.
The female ring-necked duck, on the other hand, has a more subtle appearance. She has a dark brown head and body, with a lighter brown color on her sides and belly. Unlike the male, the female lacks the ring around her neck, which further adds to the confusion caused by the common name.
Interestingly, the ring-necked duck is not the only species that can be referred to as a “ringneck.” In some regions, the term “ringneck” may also be used to describe other birds that have a ring-like marking around their necks. For instance, the Indian ringneck parakeet is a popular pet bird known for its vibrant plumage and a distinct ring of color around its neck.
It is important to note that the scientific name, Aythya collaris, provides a more accurate and standardized way to refer to this species. Scientific names are internationally recognized and help avoid confusion caused by common names. However, common names persist and can vary regionally or even from person to person.
While the ring-necked duck may not always exhibit a prominent ring around its neck, it is still a fascinating and attractive species. Its common name, though somewhat misleading, has become widely accepted. So, if you come across a reference to a ring-necked duck or black-jack duck, rest assured that it is referring to the same remarkable diving duck, Aythya collaris.
