West Coast orca 'Class of 2015' a sign of hope for endangered species

One year after a "baby boom" of endangeredsouthern residentorca whales on the West Coast gave conservationists and whale watchers hope for the population's future, most of the "Class of 2015" calves are doing great.

The southern resident killer whale population lives in three different pods in the Salish Sea off the south coast of B.C. and the north coast of Washington state.By December2014, their dwindling population was down to 77.

'Boom, we have a baby! A New Year's baby'

Then cameJ-50 a female calf first spotted onDec. 30, 2015 , in Puget Sound, Wash."Boom, we have a baby! A New Year's baby!" says Michael Harris of thePacific Whale Watch Association (PWWA), which represents 36 whalewatching and ecotourismbusinesses.

"The way this whale was born was extraordinary," Harris says, referring to the fact that researchers believe J-50 was "midwifed" by members of itsmother's pod.

"We know that because immediately we saw rake marks from teeth on J-50," he said, "and orcas don't have surgical gloves."

Then there was a baby boom.

Within one year,there were 10 known births in the population.

While two have since died, the other eight are thriving, and that's "remarkable" for a species that only has a 50 per cent survival rate within its first year of life, Harris says.

The PWWA calls them "the Class of 2015."

The 1st of the new whalesis a real crowd pleaser.

The first babycontinues to be the most energetic of the bunch, Harris says.

"Wehate to put these human value sets on wild animals, but holy smokes," he said. "J-50 came into this world and would just not stop breaching, would just not stop leaping into the air and belly flopping all over the place. And we all looked and said, 'Gosh, we're not supposed to to this, but isn't that a happy orca?'"

The calves and their mothers are thriving.

The calves should be weaning from their mothers right about now, but they won't stray far, says Harris. Orcasoften remain in the same pod as their moms their whole lives.

But orcas are still in trouble.

It's important to remember the population which now sits at 82 isn't out oftrouble yet,especially if the region's salmon population continues to decline.

"We've got fish issues,we've got tough times ahead, but for now we are just wrapping our big arms around these baby orcas and trying to fill ourselves withsome hope," Harris said. "Firefighters don't rush to a building that's alreadyburned down. We want people to understand that there is hope. This population can recover."
