They most likely moved into the U.S. as a single species, but split up as they spread across the continent and adapted to their new surroundings. The toads prefer marsh-like environments, but only enter the water to breed.

Toads, like many amphibians, exhibit breeding site fidelity . Individual American toads return to their natal ponds to breed, making it likely they will encounter siblings when seeking potential mates. Although inbred examples within a species are possible, siblings rarely mate. [6] Toads recognize and avoid mating with close kin.
Toads can only live where the ground is suitable for burrowing, and reproduce within 1 km of where they aestivate. [6] Like all amphibians, they are immobilized by low temperatures. This species prefers to burrow near large objects such as logs or rocks. They like to live near a water source, but this can be a subterranean patch of wet sand.
