Yes! Geckos are chatty creatures. They can click, chirp, and even make barking sounds because they're hungry and desire something to eat. Some of these sounds could be so high that humans cannot hear them at all! At night time, geckos use clicking sounds in order to communicate with other gecko species or just warn off competitors from their territory. The purpose is usually to avoid direct fighting but also attract mates depending on the situation for a certain breed of Gecko.
