FROG WHISPERER BADGE

Night Frog Chorus

Lesson 8.5 — Frog Sounds

EVENING MISSION

🦁

Kitimu says: "When the sun goes down, the frogs come alive! Every croak, chirp, trill, and whistle you hear is a male frog calling for a mate — and each species has its OWN unique call. Tonight, YOU become a frog detective using only your ears. Let's go, Cub!"

🎒 What You Need

Garden or outdoor area

Notebook & pencil

Torch (red light if possible)

Phone for recording (optional)

An adult companion

📋 How To Do It

Wait for dusk: This mission starts when the sun goes down! Head outside just as it gets dark — this is when frogs start their evening chorus. The best nights are warm and damp (especially after rain). Make sure you have an adult with you.
Find a listening spot: Stand or sit still near any water source — a pond, dam, stream, swimming pool, drain, or even a wet garden bed. The closer you are to water, the louder the chorus will be. Turn off your torch and let your ears do the work.
Count the different calls: Close your eyes and listen carefully. How many DIFFERENT types of calls can you hear? One might be a deep "CROAK-CROAK." Another might be a high-pitched "CHIRP-CHIRP-CHIRP." A third might be a long trill like a tiny bell. Each different call = a different frog species! Write down how many different calls you can hear.
Describe each call: For each different call, try to write down what it sounds like using words. Is it a croak? A whistle? A click? A buzz? How fast does it repeat? Is it loud or soft? Give each call a fun name like "The Deep Croaker" or "The Fast Chirper."
Record the chorus: If you have a phone, press record and hold it still for at least 30 seconds. Try to capture the full chorus. When you listen back, you might hear calls you missed in the moment! Count how many different species you can pick out from your recording.

Ranger Tip: Only male frogs call — they're singing to attract females! The louder and stronger the call, the more impressive the male. Some tiny frogs can be LOUDER than a lawn mower. Size doesn't always equal volume in the frog world!

Pro technique: Cup your hands behind your ears to make them bigger — this is how field scientists amplify frog calls without any equipment. You'll be amazed at how much louder everything sounds!
