I’ve found that they will focus,… No,… PINPOINT where the sound is coming from with incredible accuracy. As an example, and to the point of your question, ….
Say you are handcalling, and you have a stationary decoy out, and a coyote hears you and comes in, If you are at a silent point in your calling when it comes into view it MAY focus on your decoy if it sees it.
Same scenario, but you are still making sounds when the coyote comes into view, chances are good that you are going to be the focus of that coyote’s attention. Not the decoy.
Nothing is ever 100% in this game. Experience is the best teacher. You gotta have a certain amount of “Stick” to become successful at this type of hunting. If you are easily discouraged, or you’re the type to try and take shortcuts to success this might not be for you. If you have enough “Stick” and pay attention to all of the things that these experienced folks are telling you, it is an incredibly addictive sport. Good luck!
