FWIW, coyotes were unknown in rural Pennsylvania just a decade or so ago. Now, they are just starting to be a real nuisance! I’ll bet some damn PETA type introduced them.
Here’s some history on yours, but you can bet that sometime in the past trapping and hunting them was stopped or greatly reduced for awhile for political reasons. It happens a lot with all wildlife.

Check this out... Legal anytime with a license. :)
“COYOTES: No closed season. No limit. Outside of any big game season (deer, bear, elk and turkey), coyotes may be taken with a hunting license or a furtaker license, and without wearing orange. During any big game season, coyotes may be taken while lawfully hunting big game or with a furtaker license.”
