The remaining three species of toads in Alabama are a lot harder to distinguish between. To identify the differences, you have to look at the top of the head. The Southern Toad has knobs on the back of its head. The Fowler’s Toad’s parotid gland touches its postorbital ridge around its eye while the American Toads’s parotid gland does not touch or connected to it by a spur. Here’s an easy map I found that helps me.
