Necrophilous

Necrophilous (pronounced neck-ra-phil-e-us)

(1) In psychiatry, a pathological fascination with death.

(2) In human sexuality, a pathological attraction to dead bodies, especially a sexual attraction which may include intercourse.

(3) In the biological sciences, creatures (from the bacterial to the sentient) exhibiting feeding behavior in a spectrum between a preference for dead tissue and its exclusive consumption.

(4) In biology, as functional necrophilia, a reproductive strategy in some amphibians in which a male will inseminate a newly-dead female, fertilizing the still viable eggs, and then squeezing the corpse to eject the newly fertilized eggs into the water.

1892: The construct was necro- + phil(ia) + ous.  Necro was a Latinized form of the Ancient Greek nekros (dead body, corpse, dead person) from the primitive Indo-European root nek (death).  The element philia was a word-forming element meaning "friendship, fondness, tendency toward" (and more recently "abnormal attraction to") from the Ancient Greek philia (affection) from φίλος (phílos) (love, loving) of uncertain origin.  The –ous suffix was from the Middle English -ous, from the Old French –ous & -eux, from the Latin -ōsus (full, full of) and a doublet of -ose in an unstressed position.  It was used to form adjectives from nouns or denote possession or presence of a quality in any degree, commonly in abundance.  Related forms include necrophilism (apparently used first in 1864), necrophia and necrophiliac.  The primitive Indo-European (this one is properly part of the Proto-Indo-European subset) nek (the root word meaning "death) is a part of or influenced many words in Modern English including innocent, innocuous, internecine, necro-, necropolis; necrosis, necromancy, nectar, nectarine, nociceptive, nocuous, noxious. nuisance, obnoxious, & pernicious.  Connections are many including the Sanskrit nasyati (disappears, perishes), the Avestan nasyeiti (disappears), the Old Persian vi-nathayatiy (he injures), the Ancient Greek nekros (corpse) the Latin nex (genitive necis) (violent death, murder (as opposed to mors (death)) & nocere (to harm, hurt) & noxius (harmful), the Ancient Greek nekus (dead) & nekros (dead body, corpse), the Old Irish ec (dead), the Breton ankou (dead) and the Welsh angeu (death).  In English, the first mention in the literature in the sense of a "morbid attraction toward the dead" appears to be in Charles Chaddock's (1861-1936) 1892 translation of the impressively titled Psychopathia Sexualis: eine Klinisch-Forensische Studie (Sexual Psychopathy: A Clinical-Forensic Study, also known as Psychopathia Sexualis, with Especial Reference to the Antipathetic Sexual Instinct: A Medico-forensic Study), published in 1886, a book by an Austro-German psychiatrist with a name of similarly imposing length, Richard Fridolin Joseph Freiherr Krafft von Festenberg auf Frohnberg, genannt von Ebing (1840–1902), work and author respectively cited usually as the more manageable Psychopathia Sexualis by Richard Freiherr von Krafft-Ebing.  

In the wild, necrophilous creatures range from bacteria, flies and beetles to larger animals such as hyenas and vultures.  All are niche species which fulfil a role in their ecosystem(s).  Even some beasts with reputations as hunter-killers, such as the big sharks, are pragmatically necrophilous eaters, attracted always the easy snack offered by the carcass of a recently dead whale.  Necrophilia, necrophile, necrophiliac, necrophily, necrophilist & necrophilism are nouns and necrophilistic is an adjective; the noun plural is necrophilias but the more commonly used is necrophiliacs.

Vultures rarely attack healthy animals but may kill the wounded or sick if no threat exists; when a carcass has too thick a hide for its beak to open, it waits for a larger scavenger to eat first.  Entirely opportunistic, many reports from battlefields have noted the circling vultures and for an ecosystem, they’re of great value as scavengers, especially in hot regions. Vulture stomach acid is exceptionally corrosive, allowing them safely to digest putrid carcasses infected with botulinum toxin, cholera and anthrax bacteria that would be lethal to other scavengers.  They therefore play an important role in reducing the spread of disease. 

They can however fall victim to modern chemicals.  Vulture numbers in south Asia, mainly in India and Nepal, have declined dramatically since the early 1990s, the reduction caused by them being poisoned by residues of certain veterinary drugs in animal carcasses.  Action has been taken but, even if successful, it will take at least decades for the populations to be restored and without vultures to pick corpses clean, rabies-carrying dogs have multiplied, feeding on the carrion.  The decline has also threatened the age-old practice of Vultures practiced by the Parsis (or Parsees (literally “Persian” in the Persian language)), an ethno-religious group of the Indian subcontinent who practice the religion of Zoroastrianism.  According to Zoroastrian scriptures and tradition, a corpse is a host for decay, the scriptures commanding a safe disposal of the dead in a manner that does not pollute and an eight-thousand year old tradition among the Parsis is leaving of the bodies of the dead in a remote spot for vultures to devour.  With the vultures in the area poisoned almost to the point of extinction, this is no longer possible and other methods in sympathy with scripture have been adopted but none are as efficient or environmentally friendly as the big birds.

The government has begun a five-year programme called the Action Plan for Vulture Conservation (APVC).  Intended to run between 2020-2025, it includes plans to prevent the of poisoning of cattle carcasses, enhance existing conservation breeding programmes, regular monitoring of vultures numbers and extending the existing vulture safe zone network by creating at least one more zone in each state.  As most vultures die after consuming carcasses of animals administered veterinary non-steroidal anti-inflammatory drugs (NSAIDs), it’s planned to stop misuse by requiring they be sold only against prescription and ensuring all treatment of livestock is performed by qualified veterinarians.  The matter is regarded as urgent, a 2016 study finding that "…of the twenty-two vulture species, nine are critically endangered, three are endangered, four are near threatened, and six are of concern".

Homosexual necrophilia in the mallard duck

In November 2001, a researcher at Natuurmuseum (Museum of Natural History), Rotterdam, reported the first known case of homosexual necrophilia in the mallard duck (mallard Anas platyrhynchos (Aves: Anatidae)).  On 5 June 1995 an adult male mallard (Anas platyrhynchos) collided with the glass façade of the Natuurmuseum Rotterdam and died, after which, another drake mallard raped the corpse almost continuously for seventy-five minutes.  The author who submitted the paper for publication then disturbed the scene and secured the dead duck for a post-mortem examination, the dissection confirming the victim of the necrophiliac rape was male.  The researcher concluded the two mallards were engaged in an “attempted rape flight” (ARF) which resulted in the first described case of homosexual necrophilia in the mallard.

The museum’s architecture includes an all glass façade which, under certain light, behaves as a mirror and bird strikes are not uncommon and often fatal, a loud thud alerting the staff another bird has made itself available for purposes of display or research.  On 5 June 1995, the researcher responded to a thud, observing a drake mallard (Anas platyrhynchos) lying motionless on its belly in the sand and obviously dead.  Next to the carcass was another male mallard in full adult plumage without any visible traces of molt.  The live duck then forcibly picked into the back, the base of the bill and mostly into the back of the head of the dead mallard for about two minutes, then mounted the corpse and started to copulate, with great force, almost continuously picking the side of the head.

The same couple during copulation, two minutes after the above photo was taken.

“Rather startled”, the researcher, from behind a nearby window, observed and photographed the two ducks for seventy-five minutes, during which the live mallard almost continuously copulated with his dead congener; dismounting only twice, he stayed near his uncomplaining partner, picking the neck and side of the head before mounting again, his first break lasting three minutes, his second, about a quarter of an hour later, less than a minute.  After allowing love to follow its unnatural course for well over a hour, the researcher felt compelled to “disturb this cruel scene”.  At this, the necrophilic mallard only reluctantly left his “mate” not flying off but walking away a few metres, weakly uttering series of two-note raeb-raeb calls which the researcher identified as the mallard’s “conversation-call”.  Sometime later, the mallard was still present at the site of the act, still calling and apparently looking for his victim which, by then, was chilling in the freezer.

The researcher notes the supposition of an ARF cannot be verified and is wholly circumstantial, but it’s thought unlikely this was a mere opportunist event.  Disregarding the homosexual nature of the case, pursuit-behavior among mallards is commonly observed; when drakes congregate in small flocks, more than a dozen may chase a single female in the air, trying to force her down and rape her, a behavior known in the literature as “attempted rape flight” or “rape intent flights” but there appears to exist no report other than those of heterosexual ARF's although homosexual rape (referred to more delicately by some as “attempted non-consensual copulation”) is known among the mallard.  In fairness to the guilty mallard, a visual inspection of the corpse was performed because the plumage of senile females can change to resemble that of a male but the victim, although molting into the non-breeding (eclipse) stage, still showed enough male features to conclude it was no case of mistaken sexuality identity.

An exhaustive overview of animal homosexuality, published in 1999, found that in the mallard, “the proportion of male homosexual pairs varies between populations, and is anywhere from 2-19 % of all pairs” so male homosexuality can't be said to be an uncommon behavior in the breed.  Even among those drake pairs however, they do not exhibit overt sexual activity: they normally only show behavior that preludes copulation but neither partner mounts the other. Interestingly, the report added “some males in homosexual pairs have been observed attempting to rape or forcibly copulate with males outside their pair bond”.  Again, it’s speculative but this may have been the case on 5 June 1995: the drake attempted to rape the victim, which fled, the two becoming engaged in a true homosexual ARF.  Still, the unfortunate bird was dead while he was being raped although, it was noted, being dead, it may be argued by some it was no longer rape but it certainly remained non-consensual copulation and, being an act of necrophilia, this must have affected the duration of the event.  Whatever the circumstances, the case appears an avian oddity, necrophilia known in the mallard, but only among heterosexual pairs.  While occasionally, males try to mate with dead females, this does appear the first described case of homosexual necrophilia in the mallard.
