It would not be a surprise for someone who has encountered a lizard to ask: do lizards make noise? There are a lot of conspiracy about lizard being able to make noise. The good thing is that there is always an answer for anyone who is seeking the correct response.

The answer to the question: do lizards make noise? is yes, some lizards do make noise. However, it is a rarity, as only about 10% of the nearly 5,000 lizard species are known to vocalize. The most vocal lizards are geckos, which can produce a variety of chirps, clicks, and squeaks. These sounds are used for a variety of purposes, including communication, courtship, and territorial defense.

Debunking the Silence Myth: Lizards as Vocal Communicators

Lizards have long been associated with silence, often seen as creatures that operate in stealth mode. This perception, however, doesn’t tell the whole story. Contrary to popular belief, many lizard species are not only capable of producing sounds but also rely on these vocalizations for various aspects of their lives.

Briefly, let’s explore lizard vocalization using some well-known examples:

Gecko Chirps and Clicks

Geckos, particularly the Tokay gecko, are known for their distinctive chirping and clicking sounds. These vocalizations serve as both territorial calls and mating signals. Interestingly, geckos use their vocalizations not only to attract potential mates but also to establish their dominance in their chosen territory.

Anole Chirping and Chirruping

Anoles, another family of lizards, are skilled vocalizers. They produce high-pitched chirps and chirrups that are often used for communication during territorial disputes and courtship rituals. These calls help them establish boundaries and convey their intentions to other nearby anoles.

Chuckwallas Hissing and Grunting

Chuckwallas, a type of iguana native to arid regions, are known for their hissing and grunting sounds. These vocalizations are often emitted when they feel threatened or agitated. The hissing sound serves as a warning to potential predators or competitors, while the grunting can be a display of dominance.

Monitor Lizard Huffs and Growls

Monitor lizards, the giants of the lizard world, use vocalizations like huffs, growls, and hisses to communicate. These sounds are usually emitted in response to various situations, such as encountering a potential threat or asserting their dominance. Monitor lizards have a wide range of vocalizations, each serving a specific purpose in their social interactions.

Factors Influencing Lizard Vocalizations

Lizard vocalizations are not random; they are influenced by a variety of factors:

Species Variation

Different species of lizards have evolved their own unique vocalizations suited to their specific needs and environments. The variety of sounds across species reflects the diverse ways lizards communicate.

Environmental Triggers

External factors, such as temperature, humidity, and time of day, can influence lizard vocalizations. These triggers can prompt lizards to produce vocalizations as part of their responses to their surroundings.

Social Context

Lizard vocalizations are often closely tied to social interactions. From establishing territories to courting potential mates, these vocal cues play a crucial role in maintaining social order within lizard communities.

The Purpose Behind Lizard Vocalizations

Intraspecific Communication: Within Their Own Kind

Mating Calls: One of the primary purposes of lizard vocalizations is mating communication. Male lizards often use their calls to attract females during the breeding season. These calls can vary in complexity and intensity, with each species having its own distinctive “love song.”

Territory Establishment: Lizards are territorial creatures, and vocalizations play a key role in defining and defending these territories. By vocalizing, lizards signal their presence and warn other individuals to stay away.

Warning Signals: Lizards also use vocalizations to warn others about potential threats. Whether it’s the hissing of a chuckwalla or the growling of a monitor lizard, these sounds communicate a clear message: “Stay back!”

Interspecific Communication: Talking to Other Species

Predation Avoidance: Some lizards have developed vocalizations that mimic the calls of other animals, which can help them avoid predation. By imitating the sounds of larger predators, they create confusion and give potential attackers second thoughts.

Signaling Aggression: In encounters with other lizard species or animals, vocalizations can signal aggression. This serves as a deterrent, reducing the likelihood of physical confrontation and potentially avoiding injury.

Interaction with Other Species: Lizards also use vocalizations to interact with other species in their environment. For instance, they might communicate with birds or mammals to alert them about the presence of predators or other dangers.

How to Understand Lizard Vocalizations

Understanding lizard vocalizations requires keen observation and a bit of knowledge. Here’s how you can start decoding their language:

Recognizing Different Types of Lizard Calls: Start by familiarizing yourself with the various types of calls produced by different lizard species. Each call has a specific context and purpose, so knowing the basics will help you interpret their communication better.

Observational Techniques: Careful observation is key. Spend time watching your lizards in their natural habitat or enclosure. Note the situations in which they produce vocalizations and the reactions of other lizards or animals around them.

Technological Aid: Advancements in technology, such as high-quality microphones and recording equipment, have made it easier to capture and analyze lizard vocalizations. These tools can provide valuable insights into the nuances of their calls.

Lizard Keepers’ Insights: Real-life Experiences

Anecdotes from Lizard Keepers: Lizard keepers from around the world have shared their experiences with vocal lizards. From the surprise of hearing a gecko chirping to the amazement of witnessing territorial disputes among anoles, these stories highlight the rich vocal behaviors of these creatures.

Captive vs. Wild Vocalization Patterns: Interestingly, captive lizards might display altered vocalization patterns compared to their wild counterparts. This could be due to differences in environmental stimuli, social interactions, and overall stress levels.

Encouraging Vocalizations in Captive Lizards: If you’re a lizard keeper, you might be curious about encouraging vocalizations in your captives. Providing a habitat that mimics their natural environment and includes appropriate social interactions can create conditions conducive to vocal communication.

Lizard Vocalizations and Conservation

Studying Vocalizations for Biodiversity Assessment: Lizard vocalizations have practical applications in conservation efforts. Researchers can use these calls to assess the presence and distribution of different lizard species in a given area, aiding in biodiversity studies.

Implications for Ecosystem Health: Changes in lizard vocalization patterns can provide early indications of disturbances in ecosystems. By monitoring these changes, conservationists can take proactive measures to address potential threats.

Environmental Changes and Vocal Responses: Lizard vocalizations might also reflect environmental changes, such as shifts in temperature or habitat alteration. Tracking these changes through vocalizations can help us understand the effects of climate change and human activities on lizard populations.

Why Do Lizards Make Noise at Night?

Lizards are known to be more active at night, which is referred to as being nocturnal. Nocturnal lizards often use vocalizations as a way to communicate during their active hours. These nighttime calls can serve various purposes, including attracting mates, establishing territories, and warning off potential predators.

What Does the Lizard Sound Like?

The sounds that lizards produce can vary widely depending on the species. From the high-pitched chirps of geckos to the deep growls of monitor lizards, each type of lizard has its own unique vocalization. Some calls might resemble clicks, chirps, hisses, grunts, or even mimicry of other animals’ sounds.

Why Do House Lizards Make Noise?

House lizards, like geckos, are commonly found in and around human dwellings. These lizards often vocalize for similar reasons as their wild counterparts – to establish territories, communicate with potential mates, and warn off competitors. The confined spaces of our homes might amplify their vocalizations, making them more noticeable.


The notion that lizards are silent creatures couldn’t be further from the truth. Lizard vocalizations are a window into their complex social lives, communication strategies, and survival mechanisms. Lizards do make noise, and understanding their noises can provide insight into their behavior and habitat.
