All animals make some sounds when they are afraid , hurt , happy , or just want to socialize those sounds normally don't last for extended periods of time . Yes I have listened to coyote that were bothered talk for more then half an hour but that isn't the norm they had pups most of the time and were trying to get an invader out of the area of the den much the same as killdeer birds do . Some of the mistakes that I have made and learned from are so basic it scares me that I actually did them . First off I learned how to approach my calling stand then set up to call and that horse has been ridden on this site often .Next I needed to actually listen to what the animals had to say . For the most part animals don't have big lungs and can't talk as long as we can nor as loud as we can . I would venture a guess that for the most part in todays world most people have never heard the real animal make the sounds that we try to imitate . All animals make sounds but having smaller lungs and bodies then us their sounds are lower in volume and shorter in duration then most of us realize . With the advent of the e-callers a lot of people turn the volume up too high and let it play too long . Set your call up turn it on then walk down range where you would call listen to it if you can hear it at 200 or 300 yards it's too loud the animals we want to call have better hearing then we do and if we can hear it at 300 yards they can hear it at nearly a mile . Next animals all quit screaming after a minute or two at the most , they either die , get tired out or make their escape and then want to hide from what ever made them scream . I play my e-caller for a couple of minutes on a low volume turn it off for up to 10 min then just watch and listen before I do it again . After doing this a couple of times I will then turn the volume up loud for 30 sec. to 1 min. turn it off and set , watch and listen . Pay attention to what the animals tell you when they react to your calling do they hang up at 200 to 300 yards then chances are your too loud , playing it too long or moving around too much maybe you have something shinny flashing they aren't comfortable with what your doing so think back at what you did this time and see if you can figure out what you want to do different on the next stand . Try to learn about the animal you want to hunt be it coyote, fox , bobcat , deer , elk , antelope , rabbits the more you know about them the better your chances will be . Be calm , aware and enjoy what you are out there to do safely respect the land and animals they aren't dumb and we are in their home range that they know as well as we do our homes . I can only hope that I may have helped someone enjoy the art of calling more .
