mass death of animals - a phenomenon that always produces a bombshell on every inhabitant of the planet.Unexplained death of several tens or even thousands of members of a species causes fear and is often the cause of panic among the population.Why is mass death of birds (both domestic and wild)?What is the reason for causing a flock of dolphins or whales beaching?Let's try to find the answers.
In many countries around the world every year there are reports of similar incidents.Perhaps the most common was the mass death of birds.For the first time the death of a large number of birds mentioned in 1896.It happened in the US state of Louisiana.In subsequent years, it was possible to observe the rapidly increasing number of such incidents, which recorded not only in America but also in Mexico, Russia and several European countries.
most well-known cases of mass deaths of birds and animals:
- death of blackbirds in Louisiana.
- extinction of colonies of bees, honey plants in the US (more than a third of the total in 2010).
- Chilean phenomenon: the death of around 2 million. Individuals fishing of sardines, 60 pelicans, penguins and thousands of pink flamingos.
- death of black dolphins on the banks of Tasmania: nearly 200 individuals jumped on the coast of the island for one week in December 2008, and the same - in January 2009.
- inadequate behavior of pelicans on the west coast of the US in 2009 resulted in the deaths of thousands of birds.
exact reason for which the mass death of birds, ornithologists can not name.But there are a number of hypotheses that attempt to explain the causes of this tragic phenomenon.
Some researchers, who note the fact of death of animals in the same places on the planet, it is believed that the cause is a natural emission of gases from the Earth's crust, which causes the birds condition resembling narcotic intoxication, leading to disorientation and unnatural behavior.That's why they run into swarms houses, mountains and other obstacles.The release of gas can cause death, and the inhabitants of water depths.
According to another version, the mass bird deaths may be caused by the formation of the critical cold fronts of air that descend from the upper atmosphere.They cause abnormal phenomena such as freezing rain, and it can cause icing feathers of birds and destruction.We can not say that such incidents are often associated with a variety of mysterious events, such as, for example, the imminent end of the world, and blamed the notorious "bird flu."
only confirmed and obvious cause of death of animals can only be called an oil spill in the basin of the oceans.They not only poison the water, causing the death of fish and micro-organisms that are the source of its power, but also to create a thin film on the surface that covers the wings of birds, depriving them of the ability to fly.This, in turn, leads to the starvation of hundreds of individuals.
