A week or so ago I heard loud screams coming from the woods at the back of my property. I have a pond down there, behind the pond is a very large hill, on the hill there is a lot of massive oak trees, up in the trees there is a massive colony of blue herons, the screams came late at night from this back hill by the blue heron colony and I assumed it was from them because I hear them scream at dusk and it sounded somewhat similar. The scream was very loud and I called back a few times, as soon as I called out the animal would scream again, almost like it was responding to me. I had actually left my phone down at the pond that day and forgot about it till that night so I had to go grab it while this animal was screaming. The screaming animal was on the other side of the pond up on the hill, it sounded like it was coming from right under the heron nests and I thought maybe a baby had fallen or something. I did not go over there to find out what it was though because I was not sure if it actually was a blue heron, for all I know it could have been some crazy human. Well anyways, I just heard the screams again tonight, this time it was way more scary because it came from the opposite side of the woods, hundreds of feet away from the blue heron colony, it is definitely not a blue heron. Also, it sounded like two animals screaming back and forth this time. I have 12 German shepherds and they are going crazy barking at the screams, the screams are so loud that I can hear them clearly over my 12 dogs barking. I have not heard anything like this before, I live in Southern Wisconsin and the biggest predators we have around here are coyotes, I think. I am worried that this animal is gonna come mess with my dogs or kill my birds, these screams were much closer to the house than the last screams and I would prefer the animal stays out in the woods so I don't have to kill it. Does anyone have any guesses to what it could be? If you do I will look up a video of that animal to see if the screams match. I have already looked up raccoons, it is not that. I also know it is not a coyote because I am pretty familiar with their sounds.
