Yeah, its pretty well certain Canids and Corvids can recognize "human too dangerous to bother, because armed" and "human, not dangerous, prey class."
Crows and Ravens are smart and have a healthy dislike to getting shot at. They are quite capable of distinguishing human with gun from one without. Ravens in particular are known to lead hunters, both wolves and humans, to kill-able prey. Patient scavengers.
Coyote in eastern Canada (Who have learned to hunt in packs since wolves were driven to extinction) are known to have killed (chased down, brought to bay and taken down, & partially eaten, by the forensic evidence) at least one ( to my certain knowledge, and I do not follow these things closely) person, a healthy young woman on a road in a rural area of Nova Scotia.
The locals were not terribly astounded at the news.
Where my sister lives in rural Ontario, you do not let any dog out alone (2 big dogs together are ok, they protect one anothers back.) after dark (to pee for instance) , and certainly no dogs under ~20kg off leash in the dark. You do and a coyote pack comes through and... no more pet doggy, and cats too regularly vanish.
Further, I've heard enough hunter's & other peoples anecdotes about meeting and being stalked by wolves out in western & northern Canada recently that the urban legend that "Wolves/Coyotes are afraid of humans" is an old wives tale that was probably true when every rural person shot them on-sight on the principal as being dangerous pests.
The surviving wolves gave everyone the benefit of the doubt.
These days you sometimes have to make the point clear you are likely tougher than they want to bother with, so carrying a bang-stick works wonders. My friend the hunter in eastern ontario had to convince Coyotes to leave his still warm deer carcass alone, as they didn't back off until he took the rifle off his back. They FULLY understood the gesture & moved off far enough to be discreet and were yap-happy of the viscera he left behind for them.
Yes, they comprehended firearms just fine.
