ClimateWatch Science Advisor

We expect birds to start breeding and singing 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. Extreme climatic events in winter are also known to affect White-browed Scrubwren survival (Gardner et al, 2017)

When To Look

Year round. Usually breeds June to December. 

Where To Look

Coastal east, south and southwest Australia, in undergrowth of forests, woodlands, scrubs, from sea level to above the snowline; riverside thickets; heaths; bracken; saltmarsh; mangroves; parks, gardens

  1. Did You Know?

    Winter extreme climatic events affect the survival of Scrubwrens more strongly than average temperatures, whereas the opposite was found for fairy-wrens, indicating that same climatic conditions can affect the survival of similar-sized, coexisting species in different ways (Gardner et al, 2017)
