hey bamahuntin if you heard a coyote barking and carrying on this was probably a warning or alarm bark letting other coyotes know of the sight or scent of danger sometimes they do this and wont shut up until you move and they make you out for sure and then the gig is up,you have very little chance of calling anything in if they do this.They might have seen something or someone else,I've had them do it at me after missing them with my old bear recurve out of my deerstand they dont recognize you as a human up in a tree,and will stay around longer than if you were on the ground,if you are on the ground and they see you they leave at about 45mph without hesitation and usually a backside shot is all you can get.Keep on trying sooner or later everything will fall in place and you will have one rush in and make it seem so easy,but this dont happen everytime professional or beginner,if anyone tells you they call one in everytime,they are full of _ _ _ _ it dont happen thatway,just keep hunting.
