Nocturnal noisemakers are animals that make loud noises at night. The three most common nocturnal noisemakers are the CRICKET, SNORER, and hootowl. Crickets are small insects that make a chirping sound by rubbing their wings together. Snorers are mammals, usually humans, that make loud snoring noises while sleeping. Hootowls are birds that make a loud hooting sound. All three of these animals make loud noises at night, making them nocturnal noisemakers.
