Spotted like the cat they are named after, Leopard frogs emerge from their muddy bed below ice and water to join nature’s amphibian spring chorus. The mating call of the males is beautiful (at least to female leopard frogs), a mix of snoring, rattling, and grunting, and it adds to the magic of spring in a wetland. After mating, these frogs disperse to grassy areas, and are called meadow frogs in parts of the United States.
