night bird sound?
I was camping this weekend in Southeastern MN (Lansboro) and kept awake by a strange bird sound. I assume it was a bird because I could tell it was up in the tree and seemed to be moving from tree to tree. The sound would be far and then near. I think there were at least two birds.
The sound was not at all pleasant and not rythmic. It started high and got higher and then ended. I would describe it as a screech, but I listened to the sound of a screech owl and that wasn't even close. This was far more annoying. The sound went on and on through the night (until a storm hit). Can anyone give me any clues as to what kind of bird it is?
