The coywolf isn't a species (and wolves and coyotes only "diverged" ~100k years ago anyway, IIRC), but they surely became much more common in the exurban northern US after the 1960s. More generally, I believe that there's been an increase in many mid-size mammals in the northeast US as habitats became too small for the large carnivores. So it's not just extirpation and decreasing numbers, but it's also not good.
