The greatest number of calves born in a year since the records started 40 years ago was nine in 1977, and there were none born that survived in 2013 or 2014.

Researchers hope this year’s baby boom means a turn-around in what has been a negative population trend in recent years.

WATCH: After decades of decline, the Orca population off the Pacific Coast, known as Southern Resident Killer Whales, have something to celebrate.
