"Zebra Finches Sing to Their Eggs, and Scientists say This Might Help Their Babies Survive Climate Change"


"The parents launch into special songs when the weather becomes unbearable – a trait that is believed to nurture the chicks before they hatch with the ultimate adaptation skills."

“This acoustic signal is potentially being used to program the development of offspring,” says Kate Buchanan, a senior author of the new paper. “Hearing the call affects your rate of growth relative to the temperature that you experience. Animals have very subtle ways of inferring how the environment is likely to change, and (being able) to develop and adapt accordingly.”

"The hatchlings exposed to their parents’ incubation calls were found to have smaller body sizes when the nest became warmer. Smaller birds have been found to thrive better in warm temperatures because body size affects thermoregulation and energetics[4]. Smaller birds are more resilient to elevated temperatures and would have far less tissue damage than their larger counterparts."
