Swans (Latin name CYGNUS)

Family - Duck (ANATIDAE)

Migratory and non-migratory species. Where do swans spend the winter?

During its life, the swan manages to fly around and see half the world, overcome enormous distances, but always returns to the same nesting, wintering and molting places. The places of its distribution are in Eurasia, North and South America, Australia and Asia. In short, various species live practically all over the world.

In total, there are 7 species in the world:

  • Black Swan (CYGNUS ATRATUS)

Habitat: Australia, Tasmania and New Zealand.

Not a migratory bird.

  • Black-necked (CYGNUS MELANOCORYPHUS)

Habitat: South America.

Wintering sites: Paraguay and southeastern Brazil.

  • Mute swan (CYGNUS OLOR)

Habitat: northern Europe and Asia, Australia and South Africa.

Wintering sites: the north of the Caspian Sea, the Mediterranean, Africa, Asia Minor, Arabia, Iran, Afghanistan, India and China.

  • Trumpeter Swan (CYGNUS BUCCINATOR)

Habitat: tundra of North America, southern Alaska.

Wintering site: Pacific coast of Canada.

  • American (CYGNUS COLUMBIANUS)

Habitat: forest-tundra of North America.

Wintering sites: the coast of California and Florida.

  • Small (CYGNUS BEWICIKII)

Habitat: exclusively on the territory of Russia in the tundra of the European and Asian parts of the country.

Wintering place: they fly to the countries of northwestern Europe (Great Britain, France and the Netherlands), as well as to the countries of southern and southeast Asia (China, Japan and Korea).

  • Whooper swan (CYGNUS CYGNUS) Range: Eurasia,

Wintering sites: in Central and South Asia (India, the Caspian Sea) and in the south of the Mediterranean. Only a few of these birds do not fly to the south, but remain to winter at home, and if they do, then only if there is a sufficient amount of food and the non-freezing surface of the reservoir chosen for wintering. Winter finds such swans most often on reservoirs and warm water canals of power plants in large cities where they flock from frozen ponds and rivers.

The main reason for the migration of this bird - lack of a forage base in winter and severe frosts.

Swans, like geese and ducks, fly to wintering grounds in October – November as the last migratory ones and pull with departure almost until the water bodies freeze, when the rivers are already covered with a crust of ice.

Brief description of nesting

Males and females practically do not differ in appearance, and in their color they are dazzlingly white, gray or black. Even their voices are the same: shrill, trumpets. When the bird is irritated or defends itself, it hisses menacingly at the enemy.

They settle on rivers, lakes, sea lagoons and estuaries heavily overgrown with coastal and aquatic vegetation.

Feeds on various parts of aquatic plants (leaves, buds, bulbs, roots), extracting them from the bottom in shallow water, as well as mollusks, worms, small crustaceans, insects, which it collects on the surface of the water. In terms of the method of obtaining food, swans are in many ways similar to a goose or a duck: they lower their head under the water and place their body vertically, so that only the back half of the body remains on the surface of the water.

Nest is built in shallow water in reed thickets of reed stalks, with obligatory free access to clear water. It is a rather massive structure up to 2 meters in diameter and with a tray at the top. From the inside, the nest, like that of a duck, is lined with grass and down.

Appearance

The bird is large. The body length is 1.4-1.65 m. The largest males grow up to 1.8 m. An adult bird weighs 7-13.5 kg. In males, the average weight is 11.8 kg, in females this value is 9.4 kg. The wingspan is 1.8-2.5 m. The largest member of the species, officially registered, had a body length of 1.83 m, a wingspan of 3.1 m and a weight of 17.2 kg. In adult birds, the plumage is white. The beak is large, wedge-shaped and completely black. Sometimes a pinkish color is observed near the base of the beak. Legs are pale pink. In some birds, they are gray-yellow and even black. In young birds under one year old, the plumage is gray.

Reproduction and life expectancy

Couples are monogamous and created for life. A small island or a large pile of floating vegetation is selected to build a nest. One nest can be used for several years. Laying takes place in April-May. There are from 4 to 6 eggs in it. But there can be 3 and 12. It just happens rarely. The eggs are large. Each of them weighs about 320 grams.

The incubation period lasts 35-37 days. Mainly female incubates. The hatched chicks can already swim for 2 days and feed on their own 2 weeks after birth. Young people get on the wing at the age of 4 months. In the wild, the trumpeter swan lives for 25-28 years. In captivity, representatives of the species live up to 33-35 years.

Behavior and nutrition

These birds stick to their territories and drive away strangers. In adult birds, molt takes place in summer. In this case, all feathers are lost at once, and females with males cannot fly. But in females this process takes place a month earlier than in males. That is, the weak sex first sheds, and only then the stronger sex.

The diet consists of aquatic plants. These are leaves and stems of underwater and emergent vegetation. Roots and tubers are dug at the bottom. In winter, grass and grains in the fields are eaten. Feeding takes place both during the day and at night. The diet of young birds includes fish, caviar, crustaceans, along with aquatic vegetation, since the body needs protein in large quantities.

Number

At the beginning of the 20th century, this species was very rare, since people practically exterminated it. Over the past 30 years, there has been a steady increase in numbers. At the same time, growth rates increase over time. However, an obstacle to the increase in the number of birds is the increase in the number of mute swans. For example, in the Great Lakes region, it leads a sedentary lifestyle and successfully competes with the trumpeter swan for habitat. Overall, it should be noted that the outlook for population recovery is considered good with the exception of Minnesota. Today in North America there are 19 thousand of these birds.

Black (Cygnus atratus)

It inhabits the entire southwestern part of the Australian continent, New Zealand and North America (mainly in nature reserves). The bird nests in swamps, in river mouths, and also lives in captivity in zoos around the world. Despite its beauty and limited habitat, the black swan is not listed in the Red Book. Females are slightly smaller than males, both representatives of the species have black plumage, red beak. Adults reach a weight of 9 kg, size in length - up to 142 cm.In the wild, this species lives up to 10 years.
