What is that Sound?

Listen closely to this video…

I had to run to the store for a minute. When I walked outside I heard the weirdest sound. I assume it’s a bird, but could it be something else? It sort of sounds like a turkey, but I can’t tell for sure.

You are going to have to crank the volume to hear the sound on the video. It sounded like it was moving away from me and by the time I got the phone out to try and capture the sound it was too far away to really come through. On top of that you have wind, and water running down the gutter on the side of the garage, and water dripping out of a hole right near the end of the gutter too. You probably will only hear this with headphones on and the volume way up, but give it a try and tell me if you know what bird or animal makes that sound.
