There are two common toads around here, the American and Fowler's toad (Bufo fowleri). The American toad breeds first. But just to say a bit about how to tell them apart. I find two things most telling (based on research). First, each toad has black spots on its back, and while the American toad has one (sometimes two) warts inside the black spot, Fowler's typically has 3-6 warts inside the black spot. The second bit is that the crest above the eye does not join with the big lump just behind it (the parietal gland) in American toads, while it does with Fowler's toad.
So, with that babble in mind, here are some pics of American toads, in action.
