Lots of study on them here in Nova Scotia after a hiker was killed by a pair in the Cape Breton Highlands two years ago. A 93 pounder was trapped here a year ago.
Turns out we have the Coy-wolf here. I saw a documentary on TV where they compared sculls. Smallest was the coyote, largest the wolf and in between the coy-wolf. DNA also helped in this new designation. There's dog in there as well, giving them less fear of humans.
Most major cities have good populations of them. I think Detroit has an estimated 2000 coyotes. Toronto was mentioned, showing a radio collared path of one. Next time you're driving by a large on/off ramp area in a city and see a natural no-man's land area in the middle of all those vehicles flying by - good chance that's a coyotes home.
