Cool pic Greg. Better to see them than hear one scream 50' in front of you at O-Dark-30. That'll cause the color brown to be added to the camouflage pattern in your pant legs!
I heard one catch a rabbit 50' behind my stand once... I knew he lived in the area, so I was keeping a lookout for him. All of a sudden, I hear a bit of a noise like a jump in some grass, and then a rabbit cuts loose squealing. The jump was all I heard from the cat, but the rabbit's squeal was sort of eery in itself.
