Quick Answer

Male European toads can also be distinguished from females because they have nuptial pads, or spiked growths that aid with grip during breeding, on their first fingers outside of breeding season and on their first, second and third fingers during the breeding season.

Another key difference is color; male common toads have a uniform light greenish-brown or grey color, while females are darker brown with spots or bands. The male American toad has a darker throat or dewlap, which he expands to make a shrill and distinctive mating call in the spring, which is often likened to the sound of crickets.
