I was out with my partner several years ago. We called an area and struck out, so we started hunting rabbits. We spotted a jack trotting away from us, and we had turned our attention another direction, when we heard the rabbit start screaming. The screams were pretty hectic, then the screams began to move away from us. Turned out that we must have called a coyote in, because it had taken the rabbit and was running with it still screaming in it's mouth.
I have heard many birds make distress calls, and more than a few foxes in the seconds before they died.
The more you go the more you will hear.
