Why there is a mass death of birds

The mass death of animals is a phenomenon that always produces the effect of a bomb that has exploded on any inhabitant of the planet. Unexplained death of several Tens, or even thousands of representatives of a particular species causes horror and often causes panic among the population. Why there is a mass death of birds (both domestic and wild)? What is the reason for flocks of dolphins or whales to be thrown ashore? Let's try to find the answers.

In many countries around the world, there are reports of such incidents. Perhaps the most common phenomenon was the mass death of birds. For the first time the death of a large number of birds was said in 1896. It happened in the American state of Louisiana. In subsequent years, it was possible to observe a rapidly increasing number of such incidents, which were recorded not only in America, but also in the territories of Mexico, Russia, and a number of European countries.

The most known cases of mass death of birds and animals:

1. The death of blackbirds in Louisiana.
2. The extinction of colonies of honey bees in the United States (more than a third of the total in 2010).
3. The Chilean phenomenon: the death of about 2 million individuals of commercial sardines, 60 pelicans, thousands of penguins and pink flamingos.
4. The death of black dolphins on the shores of Tasmania: almost 200 individuals threw themselves on the coast of the island in one week of December 2008, and the same in January 2009.
5. Inadequate behavior of pelicans on the west coast of the United States in 2009 led to the death of thousands of birds.

The exact reason for the mass death of birds, ornithologists Can not be named. But there are a number of hypotheses that try to explain the causes of this tragic phenomenon.

Some researchers who note the deaths of animals in the same places on the planet believe that the natural release of gases from the earth's crust, which causes the birds to be in a state resembling narcotic intoxication, leads to disorientation and unnatural behavior. That's why they crash into houses, mountains and other obstacles. The release of gases can cause death and the inhabitants of the water depths.

According to another version, the mass death of birds can be caused by the formation of critical cold air fronts, which descend from the upper layers of the atmosphere. They cause such anomalous phenomena as ice rains, and may well cause icing feathers feathers and their death. One can not help saying that such incidents are often associated with various mystical events, such as, for example, the close end of the world, as well as the infamous "bird flu".

The only confirmed and obvious reason for the death of animals can be called only oil spills in the basin of the World Ocean. They not only poison the water, causing the death of fish and microorganisms that are the source of its nutrition, but also create on the surface the thinnest film that covers the wings of birds, depriving them of the ability to fly. This, in turn, leads to the hungry death of hundreds of individuals.
