Yes, this frog, only 2 inches long, can really make some noise! And it’s not a single rivet. It’s a series of rivets that have a staccato-like delivery that resembles a machine gun sound or the sound of a woodpecker pecking. The male frog produces this sound to attract females during the spring breeding season. Frogs usually make the calls near bodies of water that are suitable for breeding and egg laying. The eggs hatch in about 2 weeks and metamorphose from tadpoles in 45-75 days. The video below, shot at Zion National Park, Utah, captures the sound as I was within a few feet of one loud one.
