One of the most glamourized species of nature, swans have long been used in literature and folktales, and they represent light, purity, and intuition. They can be found in abundance in the areas of North America, Australia, and New Zealand.

If you’re an avid bird watcher and are growing curious about these birds, then keep on reading because this post contains all the information and answers to your questions that you might have about these beautiful birds.

Swans have a pure all-white plumage. Although the color variation may depend entirely on the swan species, most still have an all-white plumage. The southern hemisphere species, however, are mixed with black and white.

Here’s All That You Should Know About Swans

Swans are a member of the family of Anatidae, one of the largest members of the waterfowl family, and one of the largest flying water birds. Their closest relatives are ducks and geese. There are six distinct species of swans found across the globe.

These birds are 59 inches (1.5 m) in length and weigh over 15 kg (33 lb.). They have a wingspan of over 10 ft. (3.1 m). Compared to other relatives like ducks and geese, they are much larger and can fly and cover a great distance.

Swans mostly have white plumage, a long neck, and a sturdy bill, making them stand out from the rest of the water birds.

Are All Species Of Swan White?

undefined

There are about eight distinct types of swan species, out of which most of them have either black wingtips, back necks, or are overall covered in black feathers with white tips. Therefore, no, not all species of swans are white; some of them have a mix of black too.

Although a common picture that’s long been established in our heads is of the swan that they have to be white—which is where we get the notion that swans have to be white, but when people find out that swans can also be mixed with black or can be black overall, they don’t believe it.

Most swan species are white, but variation in their color and plumage is often seen in The Southern Hemisphere species of swans; the Northern Hemisphere swan species all have a pure all-white plumage covering their entire body, from the base of their bills to the ends of their tails.

Variations Of Colors Found In Swans

undefined

Among eight distinct species of swans, some have black feathers and others that are entirely white. There’s a variation of color found across swan species, but to say that more than two colors are present in these birds would be a lie.

There are only three colors found in swans—black, white, and at times greyish-brown!

Black/Part Black Swans:

  • Black-necked swan
  • Black swan
  • Coscoroba swan

White Swans:

  • Mute swan
  • Trumpeter swan
  • Bewick’s swan
  • Whistling swan
  • Whooper swan

Greyish-Brown Swans:

  • Leucistic swans—could be any swan species.

undefined

 It’s hard to believe that greyish-brown swans exist, but you must understand the reason behind their very being. These birds are leucistic. Leucistic swans are not familiar to many of us because their rare condition makes them hard to spot in the wild.

Leucism in swans is a rare genetic condition that hinders melanin production, which results in the irregular disposition of pigments. As a result, the pigments are either dull or muted. For example, if a bird were supposed to have a dark neck or black wingtips, it would have dull brown color in those areas instead of black.

Swan Identification Based on Their Color

undefined

How can you identify these swans and tell them apart from one another?

Well, it’s easy! Most of them have black in their plumage, and others have distinct knobs on their bills, making it easier for us to tell them apart.

Black-necked swan Black plumage covering its head and running down to its neck, a bright red knob on the base of its beak.
Black Swan Black colored plumage, a pale stripe running across the tip of its bright orange beak, few white feathers in wings.
Mute Swan Orange beak, black mouth line, black feet, a black knob on the beak.
Trumpeter Swan Black beak, black/grey feet, long thin neck.
Tundra Swan (Bewick’s Swan) Yellow blot on the base of its beak extending to its eyes, black legs, and feet.
Tundra Swan (Whistling swan) Black beak, yellow marking on beak, long neck, black feet.
Whooper Swan                                                   Yellow beak with a solid black tip, black feet.
Coscoroba Swan Reddish-pink legs, reddish beak, black wingtips.
