I watched this video once and to me at 8 min. in the coyote were all looking to their right coming in if I were calling I would think that they were in another coyotes area and it was to their right . At 15 min. in that is the coyote near the den to me and it is doing the short howl and barking that says to me it is decoying you so it can lead you away from the den . At 24 1/2 min that coyote is doing what I have talked of several times you will see them just show up and set there when you watch them they will look your way then look at the den . So then when you shoot them if you go to where they were setting get to their height and look the direction they were you should also see the den . Just some of the things that I have observed others may see it in a different way and I would welcome their observations so as too learn more thank You .
