What to Observe
- The appearance of eggs
ClimateWatch Science Advisor
We expect frogs to start calling and laying eggs earlier in the year as a result of climate change warming the Earth. They may also start appearing in new areas as warmer temperatures enable them to live in environments that were previously too cold for them.
When To Look
- From September to January.
- These frogs are rarely sighted in the cooler months but are commonly seen in the warm, wetter months of spring.
Where To Look
- In most forest types, woodlands, shrublands, open grassland and urban areas. It may be far from water, and is often in a tree. It hides during the day, often beneath loose bark on tree trunks, and emerges at night to forage and breed.
- Its eggs are found at the edges of still water.
- Within Australia, it is found in northern Victoria, New South Wales and southern Queensland.
