After the eggs hatched, the baby birds received one of two treatments—road noise or zebra finch song—for another 9 nights.

"After chasing dozens of them, the real winners were from birds," Collins said, including the zebra finch and the white-throated sparrow.

To test their technology, researchers mapped the genome of the zebra finch, a songbird that had already been sequenced to study brain development.

When studying the zebra finch vocal muscles, the team made another very important discovery.

Artificial intelligence is currently being used to understand how many species, including sperm whales, zebra finches and even our own pet dogs communicate.
