These are some of the sounds that Australian frogs make, and local biologists are hoping members of the public will help record them on a new app called FrogID.
It is part of a conservation effort to better track 240 frog species around Australia.
Scientists also believe the crowd-sourced mapping could lead to the detection of new species.
Australians are encouraged to record and upload the sounds of frogs they hear anywhere, from their suburban backyard to the outback.
