Found about 6" underground while I was digging potatoes in the garden. This toad vocalized loudly when I first disturbed it (with my fingers, not a shovel). Then it crawled deeper into the mud.
The American toad (Bufo americanus) is a common species of toad found throughout the eastern United States and Canada. It is divided into three subspecies—the eastern American toad (B. a. americanus), the dwarf American toad (B. a. charlesmithi), and the rare Hudson Bay toad (B. a. copei). A new taxonomy considers this species Anaxyrus americanus.
