they're gobbling. I love it, but being on public I hate it, because I know everyone that can hear them and will vector in on them.
Been there. Once he's told me where he is, I practically beg him to shut up!
Was set up on one a few years ago, and I hear a truck coming down the gravel road probably a quarter of mile away. It stops. I then hear the crow call.
"Please don't gobble!" "Please don't gobble!" "Please don't gobble!"
He didn't. I killed him a little later on.
