RENEE MONTAGNE, HOST:

According to a study published in the journal Science, zebra finches sing a special song to their eggs to warn their unhatched offspring when the temperature goes above 79 degrees. The warning slows the chicks' development in the egg; they come out smaller - all of which allows them to handle the heat. It's MORNING EDITION.
