The more expected toad in central and western Maryland, the American Toad is very similar to the Fowler's Toad (formerly considered a subspecies of the Woodhouse's Toad). The American Toad prefers moist habitats from yards to heavy woodlands, while Fowler's Toad prefers sandy areas near marshland. Both are primarily nocturnal, and are prodigious eaters of insects. The call of the American Toad is a musical trill that lasts about 30 seconds. The Fowler's Toad has been described as sounding like the bleat of a sheep with a cold. The most reliable way to distinguish an American Toad from a Woodhouse's Toad is to note a "separation of the parotoid glands from the cranial crests" (the glands behind the eyes and the "eye-bumps"). Both begin breeding season in March.
