This November, science needs you ... to listen to frog lovesongs. With your phone.

Scientists at the Australian Museum are launching FrogID Week, an annual national frog survey that they hope will quickly become one of the country’s biggest and most-important citizen science projects.

And it’s vital for helping preserve a critter that is vital to Australia’s environment.

To participate, all you need to do is capture a frog’s call with an app that the Australian Museum has developed for smartphones anytime between November 9 and 18 (FrogID is available for Android and iOS here).
