I have been out a few times lately, either walking into a stand or walking out and i'll hear a coyote near by start to bark or multiple dogs yipping back and forth. So i quietly get set up and start my calling. They coyotes at this point continue to yip or bark for a minute or 2, then everything goes silent without a sighting. Anyone have any ideas why they may not be responding? wind was good, And i don't believe my call would have been too loud either. If it happened once, bad luck maybe. But multiple times, i figure i might be missing something. thanx.
