The Zebra Finches' Battle to Survive

In the Australian Outback, we follow Mylene Mariette as she sets up an unusual experiment that reveals something extraordinary about the zebra finches battle to survive. When it gets really hot out here, these small birds can sing to their unhatched eggs, alerting them to the baking conditions. This in turn causes the new born chick to be smaller, increasing their chance for survival.
