The tail of the swans is short. At the top of the tail is the gland, which gives off grease to lubricate the feathers. Thanks to this lubrication, the swan can stay in the water for a long time and not get wet.
The color of the plumage of these birds is only monophonic and can be of three colors: white, gray and black. The feathering of swans consists of two types of feathers: large rods on wings, tail and podpushka on neck, sternum, stomach and back.
All their main time, swans are in the water, rarely come to dry land. On land move rather slowly due to short paws with membranes. In the water they also seem mostly lazy and slow, but when there is a danger, these birds can develop a sufficiently high speed.
Fly these birds very well, because they are flight flights. Males and females are almost the same size.
Scientists of zoologists distinguish only six species of this bird. They differ among themselves in color, neck shape and a little bit of size.
Adult individuals eat everything that floats on the surface of the pond or at shallow depth. In this case, the swans dip their long neck into the water, and the tail and paws protrude above the water. Sometimes swans go out on land and pinch green grass.
In general, swans are calm and peaceful birds. But if they get angry or they feel danger – these birds start to belligerently boil. Can use their strong and strong beak as a weapon.
