On of the interesting evolution in dart frogs are that their breeding is less seasonal. With the increase in breeding time the males also call anytime their environment fits their needs. Different species of dart frog have different calls and calling patterns. E. tricolor call most of the day, especially after rain, while D. amazonicus call briefly in the morning and evening. Below calls are grouped by relative volume and persistence.

One of the saving graces of dart frogs is that they only call when it's light out around sunrise and sunset.
