What does a frog call sound like?:

'Is it a bird?' 'Is it a plane?'….. It's a…….FROG

Frogs can be very difficult to find. They are usually highly camouflaged, blending into their environment. It's often easier to hear frogs than to see them.

Frogs have many different sounding calls depending on the species. Before you start the Frog Census it is important to recognise the structure of a frog call. In this activity students will listen to various sounds to determine what is frog and what is not a frog call.
