Known as bird strikes, the incidents are surprisingly common, with an estimated 10,760 reported strikes at US airports in 2012 alone. But despite ongoing efforts to curb the prevalence of bird strikes, experts warn that theyre likely to become more common — and that where strikes by some species are concerned, this winter might be particularly severe. Unfortunately for birds and airplane passengers alike, avian species are often attracted to the wide open spaces that are characteristic of airports. In general, birds that show up at airports are looking for three things: water, shelter, and food, says Archie Dickey, dean of Embry-Riddle Aeronautical Universitys College of Arts and Sciences who also developed an FAA database to document bird strikes.
