Well, it was much colder than predicted and by the time I spotted each of these critters, it was almost too late to get a shot at them. Both were trying to disappear into the woods when I used calls. For the coyote, I whistled and barked (bearclaw's suggestion on barking), she stopped and turned around, I fired, and then I heard the tone of the recorder saying it was about to start recording. So no video there. However on the bobcat, she was working inside the tree line and stopped to smell the coyote blood. As I was getting my rifle up, she turned and headed into the woods and I used a wounded/distressed rabbit squeal to bring her back out. For her, there is video.
At that point, the landowner was happy with what was accomplished and I was cold and so I called it an evening. The snow was nice, but it made the drive home nearly as exciting as the hunting.
