do moles make noise

2 min read 12-02-2025

Moles are fascinating, subterranean mammals known for their industrious digging. But do these elusive creatures make any noise? The short answer is: yes, but not in the way you might expect. They don't bark or meow like common pets. Instead, their sounds are subtle and often difficult for humans to detect. Understanding the types of noises moles produce, and how they produce them, provides a clearer picture of their secretive lives.

Types of Mole Noises

While not exactly "noisy," moles do produce several types of sounds, each serving a different purpose:

1. The Sounds of Digging

The most common "noise" a mole makes is the sound of its digging. Their powerful claws and specialized forelimbs create a distinctive scratching, rustling, and sometimes even a rumbling sound as they tunnel through the earth. This sound is often heard underground and can be quite noticeable near the surface, especially in quiet environments. The intensity varies based on soil type and the mole's activity level. Listen carefully near your lawn or garden, and you might hear this characteristic mole sound.

2. High-Frequency Vocalizations

Scientific studies have revealed that moles also produce high-frequency vocalizations, typically ultrasonic sounds beyond the range of human hearing. These calls are believed to play a role in communication between moles, particularly during mating season or when defending territory. While we can't hear them directly, specialized equipment can detect these ultrasonic chirps and squeaks.

3. Less Common Sounds

In some instances, observers have reported hearing faint squeals or grunts from moles, though these are less frequent and may be associated with distress or aggression. These sounds are usually only heard when a mole is disturbed or captured.

How Moles Make Noise

Moles' sound production is linked to their anatomy and behavior:

Digging: The sound of digging is purely mechanical, a byproduct of their powerful digging action.
Vocalizations: Moles have a larynx, like many other mammals, which allows them to produce vocal sounds. However, the high-frequency nature of their calls requires specialized equipment for detection.

Misconceptions and Other Sounds

It's important to distinguish mole noises from other sounds that might be mistaken for mole activity. For example:

Rodents: Mice, voles, and other rodents often produce more noticeable squeaks and rustling sounds than moles.
Insects: Various insects, especially those living underground, can create similar scratching and rustling noises.

If you're unsure whether you're hearing a mole, consider the overall sound pattern and its location. Mole noises tend to be more consistent and concentrated in areas of active tunneling.

Detecting Mole Sounds

While directly hearing mole vocalizations is unlikely, you can indirectly detect their presence through:

Listening for digging noises: Pay close attention to sounds coming from beneath the soil, especially in areas where mole activity is suspected.
Observing surface disturbances: Molehills and tunnels are clear signs of mole activity.
Using specialized equipment: Scientists employ ultrasonic detectors to pick up high-frequency mole calls.

Conclusion

While moles don't make loud, easily identifiable noises, they do produce a range of sounds related to their digging and communication. Their high-frequency calls remain largely undetected by the human ear. By understanding the types of sounds moles do produce, and how those sounds are generated, we can better appreciate these fascinating creatures and their complex subterranean lives. So, while you might not hear a "mole song," you might well hear the subtle signs of their activity beneath your feet.
