I was sitting out from a den area about 200 yards. The coyote howled when I got there. I answered back with the call. Couldn’t find any eyes with my light. One sounded off about an hour later, I responded. Dim daylight came and I spied one coming from a dead calf back to it’s home. I started HyPitch Squeak, he came to it just being inquisitive. He was looking. I dropped him at 30 yards. I wait as a general rule about five minutes after a dropped one. I am glad I did as another one was taking a different route from the dead calf to the den. It was about 300 yards out. I had run hurt pup for about a minute but it was not interested. I switched to Apple Rabbit and that got it’s attention. However, it wouldn’t come in at that point. I switched to Brassy Jack and that lit that dog up. I did not have time to turn the sound off. I have seen the Carnivore episode with Mr. Roberson where he talks about the responses to the Ultrasonic Calls. I might have questioned it until this morning. The coyote saw me but kept on coming. Just a slight change of direction and I got him at 50 yards.
