Southern Corroboree Frog Call Monitoring
Science Skill: Triangulation
The location of calling frogs can often be difficult to pinpoint accurately. In the field researchers often use a technique called ‘triangulation’ to identify a frog’s location. Three people will surround a calling frog, positioning themselves at roughly equal distance from each other and the frog. They will then move slowly and carefully towards the frog, pointing at exactly where they think it is. This technique can also be used at night with torches.
Your task is to work with other members of your group to listen to the corroboree frog calls and identify the number of calling adult males.
Did you know? Corroboree frogs were the first vertebrate to be identified to produce their own toxins and have no known predators.
