Apparently they do! I thought it was a dog at first until I saw and heard the sound coming right out of his mouth. New one for me! They never cease to amaze. I have heard them scream before (sounds like a woman screaming), especially during mating season, which is happening now. I heard one screaming as he ran past my house a couple of weeks ago. A little scary at first. The bark really surprised me, but I got a chuckle out of!
