Whooping in Taney County, Missouri

My husband and I were woke around 12:30 am with some strange sounds coning through the baby moniter. The bed room the kids are in is right next to ours but we didnt hear anything from our room, it was only through the moniter that the sounds could be heard, at first. There was a squeaking that sounded like someone was messing with the window in the kids room. My husband went to the other room to turn the outside lights on, we have lights on every side of the house(installed after an attempted brake in) while I stayed in the kids room to see if I could see what was making the noise. I was standing beside the window peaking through the edge of the blinds when the lights came on. There was another noise, something hitting/ bumping the side of the house, the same side of the window I was standing on. Then there was a big shadow moving away from the house twoard the woods. The woods are only about 10 feet from that side of the house and this shadow moved very fast. My husband returned and he looked out the window, saw nothing. We waited looking out the window for several minuets but were able to see nothing. My husband left to turn the lights out, when he returned we stayed in the kids room for a few more minuets then as we were getting ready to go back to bed we heard a very loud "whoop whoop" then again "whoop whoop" I said its an owl, even thouth I'd never heard an owl sound like that before my husband, who is former militatry and has been in combat, said if it was an owl then it had to be at least 8ft tall, then he told me he didn't know what it was but it there was no way it was an owl.
