This may be a 'new' article, but old information. 1970's & 1980's sturdies show the difference in Coyote skull plates (east-west). Eastern Coyote skull plates are more 'Wolf like' then 'Coyote like' (western Coyote). Evan today.
Studies from central-eastern Canada showed how our Eastern Coyote bred and moved to eastern Canada then down to New England parts of United States. Pretty neat to live in a time of a new species evolving.
In my youth, I never had Coyote, Beaver or Turkey to harvest in my area.

You should do a search on animal tracks to see what's running around. I never heard of a Coyote track as big as a Bear track. A Bear may have been streach'n his legs during the warm spell a few weeks ago.
