“Ree, ree, wee, wee…”

Hear that coming from the reeds this week? Congratulations, you’ve just found a common eastern froglet.

It’s FrogID Week, Australia’s biggest frog count, running until Sunday 15 November. Baby Wes headed out to Mulligan’s Flat with ANU frog expert Dr Jordann Crawford Ash to see what was calling. Every recording helps scientists track how frog populations are going across Australia. That matters because frogs are one of nature’s best early-warning signs: when they’re struggling, it usually means something’s up with our waterways and bushland.

Every frog species has its own call, so all you need is your phone. Download the free FrogID app and record a 30-second clip while you’re walking the dog or doing the school drop-off. A real-life frog expert will listen to it and identify your frogs for you. It’s basically Shazam for frogs.

Now’s the perfect time to start recording. Frogs are turning up in dams, ponds, creeks, drains and even Canberra backyards.

Bonus tip: yelling at frogs is a real survey trick, because they’ll often call back.
