That's a nice one. Is that about average size for a coyote in your area ? That's about how big they are here in southwestern Washington, but my buddies back in Pennsylvania have been killing some huge coyotes in the last several years. One guy I know well got a female that weighed 66 pounds, in the foothills of the Allegheny Mountains. Others were even bigger, but never got weighed. Some were the size of german shepherd dogs.
There is some speculation that there is timber wolf blood in these 'yotes, from their migration across Canada. The story I got from the Pennsylvania Game Commission is that they originally came from the Dakotas, and since the Great Lakes haven't been freezing over, some went around to the south ( and ended up in your neighborhood ) and some took the northern route and ended up in PA and New York.
I kinda question this, since I spent many years living in Montana where they have both coyotes and wolves. Typically, wolves don't breed coyotes - they EAT them. It's like foxes & coyotes - when the 'yotes move in, the foxes move out - or they get munched on. Do you have a lot of foxes in areas where there are lots of coyotes ?
