The American scientists attached to songbirds sensors that send signals about the art movements of the birds. It turned out that in 2014 the day before the passage of a devastating hurricane in the central part of America, all the birds flew away from the Gulf of Mexico to the south. Flight distance is more than 700 kilometers.

It is important to note that before the trip, the birds returned from seasonal 5,000-kilometer migration.

In this regard, scientists have suggested that songbirds can feel dangerous situations thanks to the ideal low-frequency hearing.

This is not the first experiment of this kind. This study was carried out with birds kind Vermivora. In May 2013, scientists ringed gauges about two dozen birds. In April 2014, 10 birds with sensors returned to America from wintering in Colombia.

«Birds of this species are very small. Their average weight is about 9 grams. The fact that 10 of them returned with geolokatorami, was a great success for us, “- said study author Henry Striba.

Scientists continue to bird watching, when they heard the warning of the approach of a hurricane.

A powerful and destructive element has brought at least 83 tornadoes. In the tragedy killed 35 people. The total damage amounted to a billion dollars.

When the storm ended, researchers conducted a trapping birds geolokatorami. Experts managed to catch five birds and remove their devices.

Tiny sensors weigh only half a gram. Despite the tiny size, they are able to measure the level of light and allow experts to determine the approximate location of the birds.

At this time, devices have pointed out that the birds did evacuate for a day or two before the hurricane.

Scientists believe that birds could feel the low-frequency hum that comes from a tornado. His sound is so low that the human ear is not able to notice it.

The ultrasonic sound can propagate thousands of kilometers from the source. It is well known that not only the birds are able to distinguish between such notification. Before the devastating 2004 tsunami in Sri Lanka, many domestic cats and dogs warn their owners of impending disasters.
