"Love is on the ground at Denver International Airport--among rabbits, at least, and that's a dangerous situation for aircraft. The wascally wabbits, as Elmer Fudd might say, attract raptors that can cause millions of dollars of damage when the birds of prey collide with aircraft.

Last year, animal strikes at DIA caused more than $4 million in damage to commercial aircraft. Bird strikes with aircraft are estimated to cost civil aviation more than $300 million a year nationally. According to the U.S. committee's website, more than 6,300 bird strikes were reported for U.S. civil aircraft in 2004."
