Bill, I was unable to see the document you referred to, but I worked for two summers with the woman in Sandusky who keeps the FAA data base for birdstrikes. This is a very serious matter not just in monetary costs but in lives lost (humans and birds). Record keeping is necessary for research to minimize such collisions. The USDA's Wildlife Services here in Sandusky, OH is one of the top research facilities in this research and their recommendations to airports, including proper management their properties, is making a difference. Whose air-space is it? Unfortunately both human and avian. It is up to us to find ways to minimize the impact (grim pun intended) of this dilemma.

Apparently Am. white pelicans average over $10 million in costs per collision! Whose air-space is it, anyway?
