Bird migrations

Bird migrations are well known phenomenon from birds life for most people. This is a process, when millions of birds owercome thousands of kilometres, to avoid difficult foodless winter conditions.

Most of our birds migrate on wintering to countries of Western Europe, Mediterranean and Africa, and only some - to Asia. Various geographical hindrances stand on the way of birds: mountainous ridges, seas, deserts. Wind, rain and snow dont assist to birds.

While migrations, birds make large flocks, which admire us by their beauty, mass and mystery. More than 10 methods of investigation of bird migrations were worked out. 12 hypothesis of their orientations in space were advanced, but no one of these hypothesis didnt explain all profundity of this phenomenon...

Migrations are accompanied by typical specifical songs and bridginal behavioral aspects. They also are accompared by definite construction of bird flocks in fligth, according to appearance of which we could determine species of birds.

Aestetic and educational significance of bird migrations are also very important.

Ten and hundred of men could observe thousands of birds, which sit down at places of feeding and rest. People could take pleasure in bird songs, behavior and affire.
