RE: "PA deer mismanagement"
My Dad talks of coyotes near Emporium when he hunted there 40 years ago. They HAVE been here that long and longer. The influx of late is due to the hybrid strains coming from Canada that are very capable of taking down healthy adult deer. My Dad talks about the "little" coyotes from 40 years ago and when he saw the big one I shot a few years ago, he said "Holy Crap, that is a different animal than the ones we used to see"!
These hybrids are decimating the deer herds in the mountainous regions and it is showing up more now due to HR. The solution is to shoot, shoot and shoot some more at coyotes. Any deer hunter that watches a coyote go by and doesn't shoot it is making a big mistake. My brother saw a black phase 'yote this year. The black and grey phases in coyotes is from wolf genes. The original little yotes that we used to have did not have these color phases, just tan.
