On January 20, 2017, thousands of birds literally ran away from the area of the US city of Houston in Texas. This event was interpreted by some as it may be a harbinger of some natural disaster that comes over the United States.
It is well known that in case of such phenomena, animals running are the first signal that somethong is going on. They instinctively sense the danger and given on the scale of this sudden migration of birds it can be really huge. The birds moved in disorganized formation, and some of them even struck the cars driving on the nearby highway.
There are no beautiful bird keys but chaos. That what happened in Texas is also named as "unjustified panic attack", which must have had a reason, after all. Some see here the sign of mother nature, others tests of new weapons, and for some it is just a scam. But the truth is that we have no idea what caused that strange behavior of birds and nothing indicates that we will find out soon.
