Instincts are heavy , except for those unfortunate times when they make an animal go totally haywire , sometimes with fatal results . Here are eight bizarre glitches that induce animals to do some very strange things — some of them even fatal .
Theant spiral of deathis the perfect example of what can encounter when instincts go haywire . Blind army ants , especially soldier pismire , bet on pheromone lead left behind by the leading emmet . As the ants move , they reinforce the trails . But if one ant wanders off an shew path , it will intertwine around and around , lead the ants behind it — all of them reinforcing the lead as they follow . This sometimes leads to large whirl vortex .

The emmet will keep up this modus operandi until they die of enfeeblement or starving — or until the whirl is disrupt .
Digger wasps arerenowned for being automatons — dirt ball with hyper - specialized genetic routines that ensue in extremely predictable and stereotypical behaviors , like nest construction and resource provisioning . Sometimes , these program behavior get the better of them , particularly when there are mischievous natural scientist around .
Digger WASP , sometimes referred to as sphex wasps , have famously been observed arriving home with a paralyzed insect , which they drop near the opening of their nest . Prior to record the nest with the entrance insect , the wasp goes inside to conduct an review , leaving its meal out of doors . But during the inspection , an experimenter can move the target a few inches aside from the opening . When the wasp go forth , it ’s ready to make for the dirt ball indoors — but its meal has been run . After relocating the bug and dragging it back to the gap , the white Anglo-Saxon Protestant will once again go through the inspection turn , leaving the insect outside . And once again , if the experimenter should move the louse , the sphex would once again relocate it and take another review . And over and over and over again .
This is actuallywhere the word of honor “ sphexish ” comes from . geezerhood ago , both Douglas Hofstadter and Daniel Dennett used this written behavior as an example of how ostensible thoughtful behaviour can actually be quite mindless — the opposite offree will .

Also calledfilial imprinting , it ’s the sometimes quirky appendage through which early societal druthers ( or “ imprinting ” ) among young birds becomes restricted to a specific object or class of objects . Imprinting happens during a abbreviated but sensible meter ( oftenon the first dayof life ! ) . usually , a chick imprint to its mother , resulting in fond regard . But sometimes this process can go awry and the chick imprint to something other than a extremity of its own species .
Impossibly cute video recording of a gosling that has imprinted to a pup :
This short Jack Russell now has a companion for life :
The life scientist Konrad Lorenzonce had a jackass embossment on his gum boots ; afterwards , the goose would follow anyone who wear the flush . NaturalistJoe Hutto became a “ mother ” to a flock of wild dud . This can be ruinous to certain birds , particularly when sexual union is concerned ; famously , George Archibald had to do a sexual union dancing with his imprinted female whooping craneto get it ready for artificial insemination .
Somewhat like to the ant vortex , sheep will blindly take after the members onward of them . This can lead to fatal outcome — like that timea herd threw itself off a 50 foot ( 15 meters ) cliff killing 400 individuals . Some 1,100 sheep survived , cushioned by the sheep lie dead at the bottom .
flock beachings of cetaceans is a spot of a mystery to scientists . These beachings can admit one individual , or even dozens at a time .
One possibility is that large giant species , like those base near Madagascar , often become beached together owing to their matriarchal nature . When the drawing card becomes ill and heads towards shore , the others are likely to survey . Another possibility is thathuman sonarisscrewing whale and dolphins up . Other theories suggest these brute were chase after a shoal of Pisces and then could n’t get back into deep water , they were being chased by predator or rivals , or they followed a phallus of the pod who get into trouble . Like the timea stray baby dolphin pulled 150 members of its fuel pod into shallow watersin Australia . ( Credit : Mirror )

bug sometimes betroth in what seems to be homosexual behaviour . For other clade , like mammals and dame , this is n’t a problem ; same - sexual urge behaviors in these species are often understood as “ practice ” for young adults and as a direction to maintain group alliances . But for insect , this is n’t the case . Indeed , these botched mating endeavour are extremely dangerous and energy - consuming . There ’s plainly no purpose for it . The reasonableness for it , say scientists , is that insects but have n’t evolved the capacity to be more discriminate in their mating alternative . This has go to “ mating discombobulation ” in which some germ seek to couple with phallus of other species — and even inanimate objective like beer bottles . Biologiststheorizethat same - sex behavior is “ worth it ” for males because “ the cost of spurn a valid opportunity to mate with a female person is swell than than of mistakenly mating with a male person . ”

amazingly , there ’s no good hypothesis to excuse why moth are hopelessly draw in to lights . It ’s widely bear , for example , that moths fly towards abnormal light source because it throws off their internal navigation system . moth did n’t evolve around smart lights , goes the hypothesis , instead adapting to the distant Lord’s Day , moonlight , and stars . Using cross preference , moth and other louse can fly at a changeless angle relative to a space light source , like the synodic month . But that possibility does n’t hold up when you consider that fires have been around for a very tenacious time , and that moths may not even use transverse orientation course . Another theory is that the infrared light spectrum emitted by a fire contains some of the same frequence of luminosity given off by female moths ’ pheromone . So maleshead to the light in hopes of sex , but are instead met with a fiery death . But this theory is not good either as moths are more attracted to ultraviolet light . [ germ : LiveScience ]
Deer are notorious for becoming impale by machine headlights . Instead of running by , they freeze in lieu to their own danger . Why is this ? C. Laiborne Ray offers an account :
“ Deer are crepuscular , ” say David C. Yancy , a deer life scientist with the Kentucky Department of Fish and Wildlife Resources . Their activity peaks within an hour or so on either side of sunrise and sunset , so their vision is optimise for very low visible light . When a headlight beam strikes eyes that are fully dilated to catch as much lighter as potential , deer can not see at all , and they immobilise until the center can aline . “ They do n’t have sex what to do , so they do nothing , ” Mr. Yancy suggested .
So it is n’t as much an fauna “ glitch ” as it is a upshot of human actions . They simply have n’t had enough time to conform .
