Coyotes have become emboldend like many other predators now that they are increasingly protected..
From time to time you must fill the air with the scent of their own kinds blood...then they get the message and have their proper fear of man and man's children.
Here... read the stuff on Freeper Varmint Al 's website if you have a moment to spare.
I grew up on a citrus farm near a river in California. Coyotes were fairly common back then (60s). My folks still own that farm. Today, coyotes are really common now. When I was a teenager, my dad would give me $10 for every coyote tail I could bring him.
I earned a good bit of spending money during my high school years shooting coyotes in the riverbed. I hunted them with a .270 rifle and an 8 power scope. My strategy was to take a position in a tree overlooking the riverbed and wait, shortly before sundown. During the Summer, I had a couple of hours there where there was enough light to hunt.
Bang!
