Certain species of birds, as well as seismologists could predict tornadoes and other natural disasters, Current Biology reports with reference to the study by researchers at the University of California at Berkeley. Ornithologists have studied the birds that live in Central and North America.

It turned out that zolotokrylye Vermivora able to predict the approach of hurricanes and tornadoes per day. Researchers were able to attach a special GPS-sensors to the birds and see the amazing phenomenon: birds displaced from their nesting, flying at 700 kilometers to the south of the Gulf of Mexico. On the day after their departure to the central part of the United States struck a wave of deadly tornadoes.

Just 24 hours later on the central part of the United States have fallen 84 tornadoes that have taken with them the life of 35 people and caused huge damage. According to the calculations of the authorities – a billion dollars. The weight of such birds only 9 grams, the experts tell of Kalifoniyskogo Berkeley.

Birds (lat. Aves) – a class of warm-blooded egg-laying vertebrates. Are well-isolated group, one of the most characteristic features of Representatives which is the covering of feathers that protects the body from adverse changes in temperature and plays an important role in flight.
