Following up on Bill Whan and Laura Gooch's comments, anyone interested in the challenges of birds on runways should read Richard Dolbeers, research, http://www.berrymaninstitute.org/journal/fall2011/12%20Dolbeer%20p235-248.pdf. He spoke to Greater Akron Audubon in October. He's a facinating speaker, wildlife expert with an international reputation on this subject. Best of all, he lives in Huron, Ohio. His talk on bird vs. airplanes is not for the faint of heart.
