context_page_description: Necrophilia, also known as necrophilism, necrolagnia, necrocoitus, necrochlesis, and thanatophilia, is sexual attraction towards or a sexual act involving corpses. It is classified as a paraphilia by the World Health Organization in its International Classification of Diseases diagnostic manual, as well as by the American Psychiatric Association in its Diagnostic and Statistical Manual.
context_section_description: Necrophilia has been observed in mammals, birds, reptiles and frogs. In 1960, Robert Dickerman described necrophilia in ground squirrels, which he termed "Davian behaviour" in reference to a limerick about a necrophiliac miner named Dave. The label is still used for necrophilia in animals. Certain species of arachnids and insects practice sexual cannibalism, where the female cannibalises her male mate before, during, or after copulation.
  Kees Moeliker made an observation while he was sitting in his office at the Natural History Museum Rotterdam, when he heard the distinctive thud of a bird hitting the glass facade of the building. Upon inspection, he discovered a drake (male) mallard lying dead outside the building. Next to the downed bird, a second drake mallard was standing close by. As Moeliker observed the couple, the living drake pecked at the corpse of the dead one for a few minutes then mounted the corpse and began copulating with it. The act of necrophilia lasted for about 75 minutes, in which time, according to Moeliker, the living drake took two short breaks before resuming with copulating behaviour. Moeliker surmised that at the time of the collision with the window the two mallards were engaged in a common pattern in duck behaviour called "attempted rape flight". "When one died the other one just went for it and didn't get any negative feedback – well, didn't get any feedback," according to Moeliker. Necrophilia had previously only been reported in heterosexual mallard pairs.
  In a short paper known as "Sexual Habits of the Adélie Penguin", deemed too shocking for contemporary publication, George Murray Levick described "little hooligan bands" of penguins mating with dead females in the Cape Adare rookery, the largest group of Adélie penguins, in 1911 and 1912. This is nowadays ascribed to lack of experience of young penguins; a dead female, with eyes half-closed, closely resembles a compliant female. A gentoo penguin was observed attempting to have intercourse with a dead penguin in 1921.
  A male New Zealand sea lion was once observed attempting to copulate with a dead female New Zealand fur seal in the wild. The sea lion nudged the seal repeatedly, then mounted her and made several pelvic thrusts. Approximately ten minutes later, the sea lion became disturbed by the researcher's presence, dragged the corpse of the seal into the water, and swam away while holding it. A male sea otter was observed holding a female sea otter underwater until she drowned before repeatedly copulating with her carcass. Several months later, the same sea otter was again observed copulating with the carcass of a different female. Copulation with a dead female pilot whale by a captive male pilot whale has been observed, and possible sexual behaviour between two male humpback whales, one dead, has also been reported.
  In 1983, a male rock dove was observed to be copulating with the corpse of a dove that shortly before had its head crushed by a car. In 2001, a researcher laid out sand martin corpses to attract flocks of other sand martins. In each of six trials, 1–5 individuals from flocks of 50–500 were observed attempting to copulate with the dead sand martins. This occurred one to two months after the breeding season; since copulation outside the breeding season is uncommon among birds, the researcher speculated that the lack of resistance by the corpses stimulated the behaviour. Charles Brown observed at least ten cliff swallows attempt to copulate with a road-killed cliff swallow in the space of 15 minutes. He commented, "This isn't the first time I've seen cliff swallows do this; the bright orange rump sticking up seems to be all the stimulus these birds need." Necrophilia has also been reported in the European swallow, grey-backed sparrow-lark, Stark's lark, and the snow goose. A Norwegian television report showed a male hybrid between a black grouse and western capercaillie kill a male black grouse before attempting to copulate with it. In 2015, due to work done by the University of Washington, it was found that crows would commi
