Planes at LaGuardia suffers rash of bird strikes

Angry Birds

LaGuardia Airport saw three separate instances of planes colliding with birds Wednesday morning, the FAA confirmed.

An Air Canada flight nearing the airport reported one such collision at 11:15 a.m., and two different ExpressJet flights called in bird strikes earlier in the morning.

The Federal Aviation Administration, which confirmed the three incidents, said that no injuries had been reported and noted that it would be investigating the situation.

While bird strikes are not uncommon-the FAA estimates that there were 11,000 wildlife collisions at 650 U.S. airports last year-they can prove costly. This is especially true if an incident occurs on a runaway, as was the case for one of Wednesday's ExpressJet flights: a 2009 study found that the total cost of an on-runway strike is about $40,000.

A spokeswoman for ExpressJet, which is owned by SkyWest , said that neither plane suffered any damage, and both have been returned to service.

Susan Elbin, the director of conservation and science for New York City Audubon, said that this time of year sees the major bird autumn migration through the area, although she had not heard of any abnormally high levels in recent days.
