Airplane collisions with birds have more than doubled at 13 major U.S. airports since 2000. Denver, Houston, Chicago O'Hare and New York's Kennedy airport reported the most wildlife strike incidents, according to Federal Aviation Administration data released for the first time Friday.

The FAA list of wildlife strikes, published on the Internet, details more than 112,387 incidents (101,995 civil and 10,392 military) since 1990, reports CBS News producer Carter Yang. The incidents involved 460 species of birds and other various animals such as deer and cows.

Of the 112,387 incidents, 3,001 or 2.67 percent caused "substantial damage" to the aircraft, Yang reports.
