If you spend much time out in the spring of the year calling coyote with vocalizations, you will get to see the coyotes trying to decoy you away from their den with pups in it or trying to draw you away from the heavy female. It's interesting they get out in plain view bark, short howl, yodel, do kickbacks ect.. I have spent time watching them doing that to try and get me, or other coyotes, to move away from their den when I would howl, and I have watched them come to the edge of their area and do the same things just to warn me not to come any closer to their territory. after they did a lot of displaying, they like to set down a lot of times and just watch if I didn't continue to talk to them. Good for the long-range shooters, I just hope that they go and take the pups too to put them out of their misery and not let them starve to death if they are young. When they are older pups often another pair of coyotes will adopt them maybe even moving them closer to their own pups, they are survivors. I have had a pair with pups adopt younger pups and carry them to their own pups and the female nurse them a couple of times, I think that the pups get to making a lot of noise when they get hungry, and mom and dad aren't there to come to them thus one of the reasons that people really get results from the puppy calls. Being a control guy, you should use that call sparingly just like you do your siren so you can have a way of killing coyotes that have been giving you a run for your money and causing a ton of trouble they are my go-to last resort I need to kill these in a hurry calls my tricks of the craft kept in reserve for those special occasions! No you don't get to see all of my cards face up on the table kind of thing.
