ATLANTA (AP) – The Georgia Aquarium has announced that one of its beluga whales is a mother-to-be.

The aquarium’s vice president of animal health confirmed in a statement Tuesday that a 20-year-old beluga named Whisper is expected to give birth to a calf in April.

The gender of the baby won’t be revealed until birth.

News outlets report Whisper arrived in Georgia from Seaworld Orlando nearly a year ago.

Previously, three newborn belugas have died at the aquarium since 2012. Still, officials say they’re hopeful Whisper will safely deliver a healthy calf this spring.
