Snarge

Snarge (pronounced snn-arj)

(1) In military & civil aviation, slang, the remains of a bird after it has collided with an airplane (ie bird strike), originally of impacts with turbine engines but latterly applied also to residue left on wings, fuselages etc.

(2) By adoption, the remains of birds and insects left on the windscreens of trains, cars, motorcycle fairings etc,

Early 2000s (probably): A portmanteau word, a blend of sn(ot) + (g)ar(ba)ge.  Snot (used here in the usual sense of “mucus, especially that from the nose”) was from the Middle English snot & snotte, from the Old English ġesnot & snott, from the Proto-West Germanic snott & snutt, from the Proto-Germanic snuttuz (nasal mucus), from the same base as snout and related to snite.  It was cognate with the North Frisian snot (snot), the Saterland Frisian Snotte (snot), the West Frisian snotte (snot), the Dutch snot (snot), the German Low German Snött (snot), the dialectal German Schnutz (snot), the Danish snot (snot) and the Norwegian snott (snot).  Trans-linguistically, “snot” is commendably consistent and its other uses (a misbehaving (often as “snotty”) child; a disreputable man; the flamed-out wick of a candle all reference something unwanted or undesirable).  That said, snot (mucus) is essential for human life, being a natural, protective, and lubricating substance produced by mucous membranes throughout the body to keep tissues moist and act as a barrier against pathogens and irritants like dust and allergens, working to trap foreign particles; it also contains antimicrobial agents to fight infection.  So, when “out-of-sight & out-of-mind” it’s helpful mucus but when oozing (or worse) from the nostrils, it’s disgusting snot.

Garbage (waste material) was from the late Middle English garbage (the offal of a fowl, giblets, kitchen waste (though in earlier use “refuse, that which is purged away”), from the Anglo-Norman, from the Old French garber (to refine, make neat or clean), of Germanic origin, from the Frankish garwijan (to make ready).  It was akin to the Old High German garawan (to prepare, make ready) and the Old English ġearwian (to make ready, adorn).  The alternative spelling was garbidge (obsolete or eye dialect).  Garbage can be used of physical waste or figuratively (ideas, concepts texts, music etc) judged to be of poor quality and became popular in computing, used variously to mean (1) output judged nonsensical (for whatever reason), (2) corrupted data, (3) memory which although allocated was no longer in use and awaiting de-allocation) or (4) valid data misinterpreted as another kind of data.  Synonyms include junk, refuse, rubbish, trash & waste.  Charlie Chaplin (1889–1977) used “Herr Garbage” as the name of the character who in The Great Dictator (1940) represented Dr Joseph Goebbels (1897-1975; Nazi propaganda minister 1933-1945).  Snarge is a noun and no derived forms have ever been listed but a creature which has become snarge would have been snarged and the process (ie point of impact) would have been the act of snarging.  Snarge is inherent the result of a fatality so an adjective like snargish is presumably superfluous but traces of an impact which may not have been fatal presumably could be described as snargelike or snargesque.

Dr Carla Dove at work in the Smithsonian's Feather Identification Laboratory, Washington DC.

The patronymic Dr Carla Dove (b 1962) is manager of the Feather Identification Laboratory at the Smithsonian Institution’s National Museum of Natural History in Washington DC where she heads a team identifying the types or species of birds that collide with military and civil aircraft.  She calls snarge “a term of art” (clearly she’s of the “eye of the beholder” school) and notes that although the scientific discipline of using snarge to determine the species involved in bird strikes began at the Smithsonian in 1960, the term doesn’t seem to have been coined there and its origin, like much slang with a military connection, is murky.  Although a 2003 article in Flying Safety magazine is sometimes cited as the source of the claim the word was “invented at the Feather Identification Laboratory”, Dr Dove is emphatic the staff there “borrowed it” from preparators (the technicians who prepare bird specimens for display or other uses by museums).  It certainly seems to have been in general use (in its specialized niche in military & aviation and wildlife safety circles) by at least the early-to-mid 2000s and the zeitgeisters at Wired magazine were in 2005 printing it without elaboration, suggesting at least in their editorial team it was already establish slang.  So, it may long have been colloquial jargon in museums or among those working in military or civil aviation long before it appeared in print but there no documentary evidence seems to exist.

The Feather Detective: Mystery, Mayhem, and the Magnificent Life of Roxie Laybourne (2025) by Chris Sweeney.

The origin of the scientific discipline is however uncontested and the world’s first forensic ornithologist was the Smithsonian’s Roxie Laybourne (1910–2003).  In October, 1960, a Lockheed L-188 Electra flying as Eastern Airlines Flight 375 out of Boston Logan Airport had cleared the runway by only a few hundred feet when it flew into a flock of birds, the most unfortunate of which damaged all four engines, resulting in a catastrophic loss of power, causing the craft to nosedive into Boston Harbor, killing 62 of the 72 aboard.  Although the engines were turbo-props rather than jets, they too are highly susceptible to bird-strike damage.  At the time, this was the greatest loss of life attributed to a bird-strike and the FAA (Federal Aviation Authority) ordered all avian remains be sent to the Smithsonian Institution for examination.  There, Ms Laybourne received  the box of mangled bone, blood & feathers and began her investigation, her career taking a trajectory which would include not only the development of protocols designed to reduce the likelihood of bird strikes damaging airliners but also involvement with the USAF (US Air Force) & NASA (National Aeronautics and Space Administration).  Additionally, her work with the FBI (Federal Bureau of Investigation) and various police forces proved forensic ornithology could be of use a diagnostic tool in crime-solving; her evidence helping to convict murderers, kidnappers and poachers.  In 2025, journalist Chris Sweeney published The Feather Detective: Mystery, Mayhem, and the Magnificent Life of Roxie Laybourne, a vivid telling of the tale of a woman succeeding in a world where feminism had not yet wrought its changes.

Snarge on the nosecone of a Cessna Citation, Eisenhower Airport, Wichita, Kansas, July 2021.  The dent indicates the point of impact, the airflow holding the corpse in place.  By the time of landing, the leaked body fluids had congealed to act as a kind of glue.

The study of aviation bird strikes is obviously a specialized field but snarge has come also to be used in the matter of insect deaths, specifically what has come to be called the “windscreen phenomenon” (also as “windshield phenomenon” depending on linguistic tradition).  What that refers to is the increasingly common instances of people reporting they are seeing far fewer dead insects on the windscreens of their cars, many dating the onset of the decline to the late 1990s and the most common explanations offered for this are (1) climate change, (2) habitat loss and (3) the increasing use (or potency) of pesticides.  Individual observations of one’s windscreen now tending to accumulate less snarge than in years gone by is of course impressionistic and caution must be taken not to extrapolate the existence of a global trend from one piece of glass in one tiny part of the planet: what needs to be avoided is a gaboso (the acronym for Generalized Association Based On Single-Observation (also as the derived noun & verb) which is the act of taking one identifiable feature of someone or something and using it as the definitional reference for a group (it ties in with logical fallacies).  However, the reports of increasingly snargeless windscreens were widespread and numerous so while that didn’t explain why it was happening, it did suggest that happening it was.

There was also the matter of social media platforms which have meant the volume of messages about a particular topic in the twenty-first century is not comparable with years gone by.  It’s simply impossible to calculate the extent to which these mass-market (free) platforms have operated as an accelerant (ie a force-multiplier of messaging) but few doubt it’s a considerable effect.  Still, it is striking the same observations were being made in the northern & southern hemispheres and the reference to the decline beginning in the late 1990s was also consistent and a number of studies in Europe and the US have found a precipitous drop in insect populations over the last three decades.  One interesting “quasi theory” was the improved aerodynamic efficiency of the modern automobile meant the entomological slaughter was reduced but quickly aeronautical engineers debunked that, pointing out a slippery shape has a “buffer zone” very close to the surface which means "bugs" have a greater chance of being sucked-in towards the speeding surface because of the differential between negative & positive pressure.  However, on most older vehicles, the “buffer zone” could be as much as 3 feet (close to a metre) from the body.  A bug heading straight for the glass would still be doomed but the disturbed air all around would have deflected a few

Lindsay Lohan with Herbie in Herbie: Fully Loaded (2005).

Herbie was a 1963 Volkswagen Type 1 (Beetle, 1938-2003) and despite the curves which made it look streamlined, its measured Cd (drag coefficient) was typically around 0.48-0.50, some 8% worse than contemporary vehicles of comparable frontal area.  What that meant was its buffer zone would extend somewhat further than the “New Beetle” (1997-2011) which had a Cd between 0.38-0.41, again not as good as the competition because it was compromised by the need to maintain a visual link with the way things were done in 1938.  On the 1963 models (like Herbie) the flat, upright windscreen created significant drag and was obviously a good device for “snarge harvesting” but the later curved screen (introduced in 1973 with the 1303) probably didn’t spare many insects.

Dr Manu Saunders' graphic example of insect snarge on a windscreen during the 2010 "locust plague" in western NSW (New South Wales), Australia, April 2010.

Dr Manu Saunders is a Senior Lecturer in Ecology and Biology and the School of Environmental and Rural Science in Australia’s UNE (University of New England) and she pointed out that “anecdata is not scientific evidence” and just because anecdotes are commonly presented as “evidence of global insect decline” (the so-called “insectageddon”), that doesn’t of necessity make locally described conditions globally relevant.  The problem she identified was that although there have been well-conducted longitudinal studies of snarge on windscreens using sound statistical methods, all have used data taken from a relatively small geographical area while around the planet, there are more than 21 million km (13 million miles, (ie more than 80 round trips to the Moon) of “roads”).  Dr Saunders does not deny the aggregate number of insects is in decline but cautions against the use of one data set being used to assess the extent of a phenomenon with a number of causal factors.
