What Does it Mean When Lizards Make Noise?

Lizards make noise for a variety of reasons.

One of the most common reasons is to defend their territory. When a male lizard feels threatened or perceives another male as a potential challenger, it will often hiss or puff up its body to appear larger and more intimidating.

This behavior is especially common in species like iguanas and bearded dragons, where males will fight for mating rights and territory.

Another reason lizards make noise is to attract a mate. Male lizards often emit sounds, such as chirping or clicking, to attract female mates during the breeding season.

This behavior is especially common in species like anoles, geckos, and chameleons, which rely on vocalizations to signal their availability and fitness.

Some lizards also make noise as a form of communication.

For example, iguanas have been observed making various sounds, from head-bobbing to tail-flicking, to communicate with other social group members.

Similarly, many species of geckos use chirping and barking sounds to communicate with each other during social encounters.

Some lizards make noise.

To express their emotions. For example, leopard geckos have been known to make a variety of vocalizations, from squeaking to growling, when they are feeling stressed, scared, or agitated.

What are the noisiest lizards?

Many people may not believe it, but lizards can be surprisingly noisy.

Some of the noisiest lizards around belong to the genus Anolis—a group of tiny tree-dwelling lizards found in North, Central, and South America.

These lizards are vividly colored, quickly adapting to their surroundings for camouflage and making loud chirping sounds during territorial disputes.

Other species of lizard, such as the frilled dragon, may sound intimidating, with the deep hissing noises they emit when upset or feel threatened; however, they tend to be less vocal than their Anolis relative.

All that said, some species of lizard, like the gecko, will rarely make any noise—so if a quiet passive lizard is what you are after, these would be your best bet.

If you’re looking for a pet lizard that won’t make much noise, you may want to consider the family of geckos.

These small, colorful lizards make great companions due to their mellow personalities and easy-going demeanor.

Geckos can make some noise, but typically not much more than a chirp or soft squeak now and again.

They also don’t require as much interaction as other pet lizards, such as bearded dragons.

With their quick movements and silent footsteps, geckos are the perfect choice if you’re looking for a small reptile that won’t interrupt your peace and quiet.
