What is the swan trumpeter?
Trumpeter Swan is a type of waterfowl with a long throat originating in North America. This bird, which was hunted almost to extinction at the beginning of the 20th century, is now quite common, although many states in the US are still again introducing Trumpeter Swan into its regions. As its name suggests that this swan has a trumpeting corner similar to calls. The scientific name for the trumpeter swan is Cygnus buccinator .
The largest water bird in North America, measures Trumpeter Swan at a length of 4.5 m (1.5 m) and weighs 17-30.5 pounds (7.7-14 kg), with a wing of up to 6.6 feet (2 m). It is almost completely white, has only a black beak and head. In the wild they can live for up to 24 years, but can live up to 32 in captivity.
In the past, trumpeter swans were found mostly around the bodies of fresh water: marshes, lakes, rivers and ponds. More recently, the coastal bays in the areas of salt water are also inhabited with frequency. Have minimal standing requirements and need only the only area of open water, food source and a place for STAVbu nest.
These swans feed on both in water and on the ground. When they were in the water, they dipped their heads under the surface and reached aquatic plants with their long necks. In addition to plants, they eat grass and grain. Young trumpeter swans eat mostly invertebrates and insects.
Trumpeter Swans Mate for a lifetime, but sometimes changing friends. They usually choose friends when they are at the age of two to four, but do not build nests or reproduce until they reach four to seven years. Nests, lined down and feathers, are made on the ground from grass and plants and are usually located on the ground surrounded by water, such as a small island. Females perform most of the work, but the creation of nest is a common effort.
women lay one to nine eggs and incubate them for 32-37 days. Men sometimes help to incubate, but more often watch the nest. Once the floats, the Downy Young can swim and feed after just 24 hours but require help JEjich parents to lead them to feed areas. Three or four months after hatching, young, now gray white, can fly.
southern populations of trumpet swans are non -migrant, but the northern populations at the end of autumn migrate south. He returns to start nesting early in the spring, usually while the waters are still icy. The greatest concentration of these swans lives in Washington and Canada.
In the past, trumpeters have been awarded for their feathers, which were used for the production of high quality British. Two hundred years of extensive hunting decreased by 1930 in the US to just 100 species of trumpeter to only 100. However, the effort to protect this species has made it possible to increase its number and since 2010 has been in the United States.
