What is the Meaning & Definition of flock

Known as flock to the phenomenon by which a more or less large group of birds fly over the skies in an organized way and forming unique and highly conspicuous figures. The term Flock is used exclusively for flocks of birds and composed the same meaning as the term of herd for mammals.
The flocks of birds are usually composed of a particular type of birds, swarms that form in particular situations in which the birds in question are attached to fly or move together. Anyway, this is not so at all times. In many cases the flocks of ajaros may have different species characteristic of a region coming together for certain reasons. Although in many cases these flocks can form to travel long distances, they are also known for form in cities in which there is a large population of urban birds (such as pigeons or sparrows), in whose cases the birds do not seek to emigrate if fly not simply spontaneous and jointly.
As in all animal community organization, flocks, while they may seem cluttered or chaotic to the human eye, involve a clear hierarchical as in them you will find birds and leading birds as well as birds also weaker. At the same time, the flocks of birds are especially useful when it comes to fend off possible predators since, in large numbers, birds may show greater defense than individual. Finally, flocks are also generated to spot more quickly and accessible areas of habitat for migratory birds.
The flocks are decidedly one of the most extraordinary phenomena that can be observed. In general, the flight of birds that make them form a multitude of figures that are extremely private and, overlooking distance, shown as a black block in the sky that is armed and disarmed so spontaneous and unique.
