The FAA attempted to gather data on bird strikes by means of Form 5200-7, the Bird/Other Wildlife Strike Report. During a 17-year period, it collected more than 80,000 reports of bird strikes, but concluded that these represented only a fifth of the actual occurrences. If this is the case, then bird strikes occur at a rate of almost 65 per day. However inaccurate the tally may be, however, it is a very large statistical sample and provides a good deal of insight into the character of the hazard. Sixty percent of strikes occurred at or below 100 feet agl, and 92 percent at or below 3,000 feet. (Both the Wiley Post Citation and the LaGuardia A320 met their matches at 3,000 feet.) Not surprisingly, very few strikes occurred during cruise. Most pilots would probably be surprised to learn that more than a third of bird strikes occurred at night. Responding to NTSB concern that bird-strike reports often lacked reliable information as to the type of birds involved, the FAA contracted with the Smithsonian Institution in 2000 for the identification of bird-strike remains, which, by the way, when sufficiently scrambled, are known to specialists as "snarge."
