Geckos are vocal reptiles, unlike many other lizards. They use a variety of sounds to communicate, engaging in a complex auditory world often unnoticed by humans. Their diverse vocalizations serve many purposes, contributing to their survival and social interactions.
Common Gecko Sounds
Geckos produce distinct sounds, including chirps, clicks, and barks. Chirping is a common vocalization, often soft and repetitive, sometimes sounding like “chuck, chuck, chuck” or “tup, tup, tup” notes. These sounds vary in intensity across species.
Clicking sounds are prevalent, characterized by sharp, rapid noises. Larger gecko species produce surprisingly loud barking sounds, often associated with warnings or territorial displays.
Geckos may emit squeaks when alarmed or distressed, and some species can produce louder screams when in extreme fear or pain. Hissing is another defensive sound used to ward off threats.
Why Geckos Vocalize
Gecko vocalizations serve diverse communicative purposes for their survival. A primary reason is territorial defense. Male geckos use loud chirps or barks to warn off rival males, helping avoid physical confrontations.
Vocalizations are crucial for attracting mates. During breeding season, male geckos use distinct calls, like chirps, to signal their presence and attract female partners. These mating calls can range from soft chirps to more assertive sounds.
Geckos vocalize to communicate alarm or distress. A high-pitched squeak or hiss can startle predators or alert other geckos to danger. Younger geckos are particularly prone to vocalizing when upset or threatened. They also use sounds for general communication, signaling their presence or interacting within social groups.
Species-Specific Sounds
Gecko vocalizations vary considerably across species, with some known for distinct calls. The Tokay gecko (Gekko gecko) is famous for its loud, repetitive “to-kay” call, which names the species. Males primarily use this call to attract females and establish territory, adjusting it in noisy environments.
Leopard geckos (Eublepharis macularius) are quieter, producing softer sounds. They make gentle chirps, clicks, and squeaks, indicating contentment, distress, or interest. Chirping can be a mating call or signal discomfort, stress, or even hunger. Barking is a rare sound, indicating fear or threat.
Common house geckos (Hemidactylus frenatus) are known for their soft chirping or “chapping” calls. These sounds are a familiar nocturnal noise in tropical regions, used for communication and territorial warnings. Crested geckos vocalize with chirps and squeaks, particularly males attracting females.
