There are lots of ways animals are adapting to the earth’s changing climate. Armadillos and some small critters are moving north. Atlantic killifish have learned to survive in both freshwater and saltwater. Now scientists have discovered that Australian zebra finches sing to their eggs to prepare them for warmer weather.

Researchers at Deakin University in Melbourne studied more than 100 nestlings, some of which received the “incubation calls” before hatching, as they grew in different temperature environments. They found that those that received the calls grew differently than the other finches they tested.

Watch the video to see what they learned, and what light this can shed on the impact of prenatal sound more generally.
