The tokay gecko (Gekko gecko) is one of the best-known gecko species when it comes to vocalization. Its loud, rhythmic “to-kay, to-kay” call can carry over long distances and plays an important role in communication.
Calling is especially typical of males. It may help mark territory, keep rival males away, and attract the attention of females.
The species’ name also refers to this distinctive sound. The vocal behavior of the tokay gecko is a good example of how reptile communication can be much more complex than it may first seem.
