I hunted a property in Marengo County (Nanafalia) on the Tombigbee River for a few years that was infested with them. They are blind as a bat but can smell better than a bloodhound. You could sneak up to them on the logging roads in the river bottom before the leaves dropped. We figured out that you should always take your bow when scouting and checking cameras because they liked making wallows in the logging roads. I have stood beside a water chestnut oak and had several sows and piglets walk right by me and never know I was there only to spook when they got down wind. Not an expert but you are most likely going to have feral hogs-descendants of escaped domestic swine that are not aggressive unless cornered. Russian wild boar are a different story. I have never seen one or have heard of them being in Alabama.
