A short breath extends the mating calls of male tokay geckos

Tokay geckos (Gekko gecko), large and mostly nocturnal geckos native to parts of Asia, are among the few nonbird reptiles that make sounds to attract potential mates, defend their territory and signal distress. Male tokay geckos' calls typically begin with quieter rattles, followed by louder two-part sounds that can sound like "ge-ko" or "to-kay."
