I went hog hunting this past week. It was a bit on the warm side but we saw some hogs but were only able to connect with one of them. One night I was hunting a stand on an edge of a swamp. Over the course of the evening, there were 5 raccoons on the bait of varying sizes. I heard some splashing back in the swamp so I got my thermal up and watched the bait site with all the raccoons. The raccoons all looked in the direction of the splashing noise and then all of a sudden I heard what sounded almost light coyotes yelping and the raccoons started getting excited and were jumping around. This went on for a few seconds before I finally heard a pig grunt and all of the pigs in the sounder turned around and went back the way they came. I never saw any coyotes. I think what I heard were the raccoons barking. It was almost as if they knew the pigs were coming in to run them out so they all started making a huge ruckus and scared the hogs away. My friends said I was full of it and it must have been something else because they had seen hogs run off raccoons on numerous occasions. I have witnessed this as well but the raccoons never started barking and going crazy when the hogs came in before. The wind was in my favor so I know it was not me that scared them off.
