We do have a window where the birds were found. I don't know if that is it though because the first bird's head was missing and the wing was torn off and in the morning the body was gone. (Ew...sorry for the graphics.) Last night we had our metal screen open and heard what I thought was footsteps coming toward our door. It kind of freaked me out. Then there was some rustling and nothing/nobody was there. We have no bushes around our stoop, only a huge pine tree. My husband and I both heard it, looked out the window, saw nothing and figured it was an animal. When we left the house an hour later, there was the dead bird. I cannot say if it was there two hours earlier when we came home or not because our porch light was off when we got home so it was dark. We are only weekenders so I couldn't check to see if it was still there or not. Two birds in one week in virtually the same place made us wonder what was going on.
