Researchers from UC Berkeley have suggested that golden-winged warblers can predict the coming of storms and tornadoes.
In April, central and southern United States were badly hit by a massive thunderstorm which caused damage worth over $1 billion in damage across 17 states. Just two days before the storm hit these areas, flocks of songbirds and golden-winged warblers departed the areas leading the scientists to believe that the birds can hear the incoming storms.
"At the same time that meteorologists on The Weather Channel were telling us this storm was headed in our direction, the birds were apparently already packing their bags and evacuating the area," Henry Streby, a population ecologist from the University of California, Berkeley, said in a statement.
The warblers flew 1,500-miles down to Tennessee and then suddenly switched their path and flew 900-miles to Florida and Cuba. The movement forced researchers to think why the birds would travel so far from their migratory route and after analyzing data the researchers were surprised to find that it coincided with the comings of storms.
"Biologists had not been looking at the use of infrasound in this way, but it certainly makes sense to me," Jon Hagstrum, a geophysicist at the U.S. Geological Survey who linked pigeons and infrasound, said in a statement. "We may find that acoustics are a pretty significant way that birds in general view their environment, much like dogs use olfaction and humans use sight."
