New York, I believe that’s a red fox barking.
As to your bait site, is it possible or practical to remove some underbrush / saplings as well as a strategic tree or two? If so, that could increase your chance of getting a shot. As well, coyotes in general are nervy and don’t stop moving for very long, so you pretty much have to be ready to shoot when they do stop.
Also, what type of sensor are you using? Does the sensor emit a glow when activated? Just trying to consider possibilities to enhance your bait site.
