Busshaped birds representatives and types of detachment, meaning and features, signs and nutrition

The cubeshaped detachment is a rather ancient group, the early finds of which were made in Paleocene. Suggest the chalk age of the detachment. The ancestors of these birds are ground vegetable birds, which have external similarities with kurozhny. At the moment, the detachment combines about 150 different types, the bulk of which belongs to the family of duck. In total, the detachment contains about 46 genera. On the territory of Eurasia there are 59 different types of gooseshaped, of which 17 representatives belong to the subfamilies of goose, and 42 species to the subfamily duck.

Characteristic signs of bugsshaped

A distinctive feature of the gooseshaped is the presence of membranes on the legs between the three fingers directed forward. They are important for moving through water. However, they have practically disappeared from the palazes and a halfloin goose, which spend almost all of their time on land and do not go into the water.

The plumage of all birds is waterproof, and some representatives are very colorful painted. Bright color is characteristic of males. Birds devote a large amount of time to care for the plumage. It is lubricated with a special waterproof secret that the glands located on the skin of birds are secreted. During the molting period, many birds disappear, therefore, for selfdefense, males can only demonstrate a very discreet color.

Membranes of the paws of the gooseshaped

Thermal insulation is ensured by the thick layer of fluff, as well as the presence of a layer of fat in the subcutaneous layer.

The value of the gooseshaped

In the nature of the bird of the cubic detachment are an important link in the power chain. More overall animals are hunting for them. Also, birds clean water bodies and rivers from algae and duckweed.

The representatives of the cubeshaped detachment organize amateur hunting. As a rule, they hunt with a gun. Poachers can carry out illegal hunting using prohibited types of weapons and fishing methods. As a result, the natural population of these birds is greatly undermined. They have valuable meat, highquality pen and fluff, as well as down skins. Most of the birds of the detachment are domesticated, which explains their high value for humans. People breed these animals to obtain eggs and fats.

Plumage and appearance

The water lifestyle of the gooseshaped determined their dense and cotton body. It has an elongated shape, and in some species and a very long neck, which allows you to easily extract the booty from the water. Fourfingered legs are small long and slightly set back. The front three fingers are relatively elongated and are connected using a swimming membrane. The rear finger is short and located just above the level of the front. Most birds are wide and thickened. It is covered with a sensitive and thin skin, which on the top is converted into a keratinized thickening. Such a thickening is called “nails”. At river ducks, the edges of the supracloudy and connection with narrow transverse horn plates forms a vehicle. In birds such as crumbling, they are seated with horny teeth that help to firmly keep caught prey in the beak. Geese and barracks are characterized by a rigid transverse plate along the edges. It allows them to easily pinch grass.

The plumage of representatives of the detachment of the gooseshaped dense and dense. The amount of fluff is quite large, evenly distributed in the body. Feathers do not have a side barrel. Coloring can be extremely diverse. Quite often, males and females are distinguished precisely by the color of their plumage. Also, sexual dimorphism can consist in size. Males are often larger than females.

Wings of a hoseshaped small size with a pointed shape. The tail is short. During the flight, birds often wave their wings, and the ends of the feathers make special sounds. Some birds practically do not fly. For example, southern American ducks do not fly due to strong reduction of wings. The speed of movement on the ground is quite low. As a rule, they go ahead. But there are exceptions, for example, geese and barracks can move very quickly by land.

Distinguishes a detachment excellent ability to swim and dive. They can reach a depth of 40 meters and stay under water for 4 minutes. There they move with their feet or wings. Some birds of the detachment do not dive. They get their food, immersing only the front of the body and neck in the water.

What they feed on the bugs

The main diet of the hoseshaped birds consists of fish, crustaceans, water mollusks and insects. They look for their prey in water or near it. Some representatives feed on water plants. They dive behind them with their long neck. Types such as geese and barracks are feeding on land. As food, they prefer herbaceous plants. Birds of this detachment tend to regularly swallow small stones that help grind food in the muscular stomach.

Habitat

The cubes have spread almost throughout the world, with the exception of the Antarctic. The most diverse species composition in the tropical regions of South America, Africa and Australia is.  They live in the aquatic environment. As a rule, these are lakes, ponds, swamps, rivers and tops. There are species that live in the marine environment.
