The birds (Aves class) represent a group of four-legged vertebrates which have evolved from reptiles, keeping some features of these animals. They are the first vertebrates which have the possibility of preserving a constant body temperature.
The most important characteristic of birds is their flight adaptability.

By virtue of this fact, the birds are the most widespread species in the world, breaking down the geographical barriers, traveling at large distances, conquering lands with a harsh climate. The winter and summer migration is widespread at several birds species.

The Aves class includes approximately 8650 species grouped in 28 orders. Birds like ducks, geese, swans are part of the Anseriformes order. The 200 species are grouped in two families.
Generally, the birds of this order have a prolonged trunck belly, sometimes heavy, but middle seized. The beak is long, flattened and the tongue is big and smooth. The legs are short, with three palmed fingers and a little thumb, placed in the back. The feathering colours are diversified, both for the females as well as for the males. The feathers are waterproof,compact and dense on the entire surface of the body. Therepresentatives of the order are good fliers but also goodswimmer; they migrate according to the seasons and thenesting places. We can find them in the shore areas of stagnantand running waters or not, and they nest in the margin thicket.
