when i write About European starlings and their complex tales of North American origin, I didn’t expect readers to be so fascinated by a particular word in the article: snarge. But like emails, tweets and other feedback poured in, it turned out that the bitter-sounding six-letter word and the field of scientific research that created it deserves a closer look.
On October 4, 1960, a Lockheed L-188 Electra aircraft nosedive into Boston Harbor seconds after takeoff. Of the 72 crew and passengers, only 10 survived.
As investigators sorted through the rubble, they continued to find globules that looked like black fluff. This type of material eventually came to be known as snarge.
The best researchers would have guessed that Electra’s engines had swallowed a flock of birds, but no one could say what kind of bird could bring down an airplane this size. So investigators called Roxie Laybournean ornithologist at the Smithsonian Institution who specializes in feathers.
Miss Laybourne compared the microscopic patterns in the feathers with a large collection of museum specimens. What devastated Electra wasn’t a large-bodied bird like a vulture, turkey, or crow. Rather, the plumage was down to tiny European starlings.
Years later, airports would hire wildlife biologists to take the information Ms Laybourne provided and deter certain bird species from flocking on their flight paths. By contrast, Miss Laybourne would become a science and air traffic safety legend known as. hairy woman. You’re right to call her the Snarge Queen.
carla pigeonprogram manager for The Smithsonian Institution’s Feather Identification Laboratory and Mrs. Laybourne’s successor said she wasn’t sure who first used the term snarge, but first heard of it at the museum.
Snarge may have been part of a Canadian goose encased in an aircraft engine. Or it could be a broken and burnt seagull feather strewn across the runway. Snarge can be as small as a rusty-red speck on the nose of an airplane.
But no matter what form, every trap is different – and all traps are important.
In Miss Laybourne’s time, physical comparison of snarge samples under a microscope was the industry standard.
Dr. “She cleaned and washed the feathers and then matched the pattern, colors and texture to the museum specimens,” Dove said.
Dr. Dove and colleagues now also use DNA analysis because a trap sample may not always contain a recognizable piece of feather. In some cases, samples may be too small or degraded to obtain DNA, so they solve the mystery with a number of techniques.
Identifying the origin of the Snarge has real-world implications. After starlings were infected in the Electra crash, the deadliest ever caused by a bird strike, the airline industry began building engines with these crashes in mind. Many aircraft models can now be expected to survive a bird strike to death. eight pounds.
But even these technological advances do not mean that an airplane is vulnerable to bird strikes, as Chesley B. Sullenberger III and his passengers learned that in 2009 Canadian geese shot down their Airbus A320 in what is now known as the event. Miracle on the Hudson.
Of course, even small animals can have a deadly effect.
“Starlings are called feathered bullets,” said Richard Dolbeer, science consultant for the Airport Wildlife Hazards program, which is part of the U.S. Department of Agriculture. “A dense, stocky little bird with a higher body density than many other bird species.”
Since the 1960s, the Feather Identification Laboratory has worked with the Federal Aviation Administration and wildlife biologists at every major airport to identify problem birds and deter them from hanging out nearby.
Management options include capturing and relocating some birds or scaring others with trained hawks, noise cannons and distress calls. In rare cases, they resort to lethal measures.
Other strategies include removing standing water, removing garbage or food scraps, and placing nets over roost areas.
Dr. “Really, we just want to make the airport as uncomfortable as possible for the birds,” Dolbeer said.
Despite these efforts, the snarge happens. Wilbur Wright crushed a flock of birds in 1905, and in modern times, with more flight in the air than ever before, planes are hitting birds every day. Only in 2019, FAA certified 17,358 strikes. Fortunately, the vast majority do little or no harm.
Perhaps the most interesting: Snarge is not limited to birds.
Bats and insects turn into traps. There are even more curious species emerging, including frogs, turtles, snakes, and even cats and rabbits.
Explanation?
Sometimes a raptor is frightened by an approaching plane and drops whatever it is holding in its claws and is then sucked into a jet engine. Dr. It’s also possible that when a bird and a plane collide, the contents of the predator’s stomach splatter with the rest of the bird, and the DNA still shows up in genetic testing, Dove said.
It’s never a dull day when you’re in charge of Snarge.
