In 2009 , a pack of coyotes hold out in Canada ’s Cape Breton Highlands National Park drink down a 19 - class - old tramp in a seemingly unprovoked attack . It was the first coyote - relate killing ever document in Canada and only the 2d in North America , following the 1981 expiry of a toddler in California . More than a 10 later , scientist now think that they have figured out exactly why the tragedy occur . They argue that the car park ’s coyotes had get down hunting large animals like Alces alces due to their limited resources , which then made them more probable to go after humans . They rein out other potential causes , such as the coyote becoming more familiar with humans or their food over time .
The death of singer - songwriterTaylor Mitchellin late October 2009 floor many , including coyote experts . Despite public perception , prairie wolf are n’t know to be aggressive toward humans . Even in urban area shared by the two species , the animals will often avoid human liaison .
A team of scientists in Canada and the U.S. have been consider the possible circumstances behind Mitchell ’s death . Their investigation has include the capture of nearly two 12 coyote in the country between 2011 and 2013 , which allowed the squad to outfit them with gadget to tag their movements . They also hoard whisker sample from the Canis latrans ( including the animals implicated in Mitchell ’s death ) and fur sample distribution from potential target in the region , as well as hair samples from a local barbershop . By studying the nitrogen and carbon paper contents of these samples , the squad was able to estimate the late diet of the coyotes , admit whether they had deplete food meant for humans .

prairie wolf generally hunt or scavenge small target , though they ’re omnivores that can eat most anything if the opportunity is there . But the squad institute that the Cape Breton Canis latrans were mostly eating European elk , with the large animal accounting for half to two - one-third of their diets on fair , follow by small mammal and deer . The same pattern was true for the coyotes responsible for Mitchell ’s destruction . And unlike coyotes elsewhere , there was small seasonal variation in their diets , suggesting they were primarily hunt down moose throughout the yr .
The replacement to expectant quarry seen in this Canis latrans population would in all likelihood only happen out of sheer essential , the author argue , and it ’s this unique adjustment that predispose them to attacking Mitchell .
“ We ’re describing these fauna expand their ecological niche to basically rely on moose . And we ’re also accept a step forward and say it ’s not just scavenging that they were doing , but they were in reality kill moose when they could . It ’s arduous for them to do that , but because they had very little if anything else to feed , that was their prey , ” tell lead author Stan Gehrt , a wildlife ecologist at OSU , in astatementfrom the university . “ And that leads to conflicts with multitude that you would n’t unremarkably see . ”
Gehrt and his team also collected evidence that target aside from other common hypothesis for the attack . The coyote in the park had an expansive grasp , but they still tended to avoid area that overlapped with human natural action . They also move more often at night during periods of the year when man were most active in the daytime . And only a handful of the coyotes had of late eaten human intellectual nourishment ( including one of the coyotes need in attack on humans ) , further tighten the theory that these animals are pass much time near us . Lastly , hunt and trapping is n’t allowed in the park , signify that local coyotes may not revere mankind as much as they typically do elsewhere .
“ It ’s a braggart area for these coyotes to live in and never have a negative experience with a homo — if they have any experience at all , ” Gehrt said . “ That also leads to the lucid assumption that we ’re making , which is that it ’s not operose for these brute to prove to see whether or not people are a potential prey token . ”
All in all , the findings , publishedlast month in the Journal of Applied Ecology , intimate that what materialise to Taylor Mitchell was a tragical but “ quite rare ” occurrence , the study author say . The conditions that led to her death are especially improbable to befall in places where coyotes have plenty of food and natural prey to use up , include urban area shared with humans . At the same time , people visiting the ballpark or other area with similar environmental condition “ should be made aware of the risks coyotes pose and encouraged to take precautions , ” they indite , such as lend along a mate and animal balk like bear spray . parkland director in these areas may also ask to carefully supervise coyote behavior and be willing to take action earlier than usual , which could include the culling of fast-growing coyotes .
Though there have beenreportsof coyote attacks in the parking lot in the year since , no other deaths appear to have happen .
