Some interesting statistics from

DID YOU KNOW THAT?
· Over 219 people have been killed world-wide as a result of bird strikes since 1988.
· Bird and other wildlife strikes cost USA civil aviation over $620 million/year, 1990-2007.
· Over 5,000 bird strikes were reported by the U.S. Air Force in 2007.
· Over 7,600 bird and other wildlife strikes were reported for USA civil aircraft in 2007.
· Studies indicate only about 20% of bird strikes to civil aircraft at Part 139-certificated (passenger service) airports in USA are reported. Less than 5% of bird strikes at General Aviation airports are reported.
· From 1990-2004, USA airlines reported 31 incidents in which pilots had to dump fuel to lighten load during a precautionary or emergency landing after striking birds on takeoff or climb. An average of 11,600 gallons of jet fuel was released in each of these dumps.
· Waterfowl (31%), gulls (26%), and raptors (18%) represented 75% of the reported bird strikes causing damage to USA civil aircraft, 1990-2007.
· Over 760 civil aircraft collisions with deer and 250 collisions with coyotes were reported in the USA, 1990-2007.
· In 1890, about 60 European starlings were released in Central Park, New York City. Starlings are now the second most abundant bird in North America with a late-summer population of over 150 million birds. Starlings are "feathered bullets", having a body density 27% higher than herring gulls.
· The North American non-migratory Canada goose population increased 3.6 fold from 1 million birds in 1990 to over 3.5 million in 2007. Over 1,400 Canada geese strikes with civil aircraft have been reported in USA, 1990-2007. Over 40% of these strike events involved multiple birds.
· A 12-lb Canada goose struck by a150-mph aircraft at lift-off generates the force of a 1,000-lb weight dropped from a height of 10 feet.
· The North American population of greater snow geese increased from about 50,000 birds in 1966 to over 1,000,000 birds in 2007.
· The nesting population of bald eagles in the contiguous USA increased from fewer than 400 pairs in 1970 (2 years before DDT and similar chlorinated-hydrocarbon insecticides were banned) to over 11,000 pairs in 2007. Over 100 bald eagle strikes with civil aircraft have been reported in USA, 1990-2007. Mean body mass of bald eagles = 9.1 lbs (male); 11.8 lbs (female).
· The Great Lakes cormorant population increased from only about 200 nesting adults in 1970 to over 260,000 nesting adults in 2006, a 1,000+-fold increase.
· The North American white and brown pelican populations grew at average annual rates of 2.3% and 1.9%, respectively, 1966-2007.
· At least 15,000 gulls were counted nesting on roofs in USA cities on the Great Lakes during a survey in 1994.
· About 90% of all bird strikes in the U.S. are by species federally protected under the Migratory Bird Treaty Act.
