There are lots of different barks. The "Your Busted" vocalization is very distinct. Once you hear it, you will remember it. If I have coyotes that vocally respond and I typically move to 100% vocalizations if I haven't already. If it is "Your Busted", you probably aren't getting this coyote to come in. If it is more a territorial bark, etc, you can often get them to commit by getting them more angry. I will usually use some type of super aggressive vocalization back (the older the coyote sounds, the deeper the sound of the barking, howling I will respond with) followed by either fighting sounds, submissive female sounds, or kiyis.
