Researchers name newest baby orca spotted in B.C. waters

A young southern resident killer whale spotted swimming in the waters off the west side of Vancouver Island now has a name.

The Center for Whale Research (CWR) based in Washington state says it has dubbed the latest addition to the K pod as K45 after staff spotted it in a tight group with other family members northeast of Race Rocks, an ecological reserve at the southern end of Vancouver Island. 

The centre says it received video and photographs of a possible new calf in April and June, and a field biologist is among those who have confirmed its presence, though the calf’s sex is not yet known.

It says K45 is K pod’s first baby since 2011, when K27 gave birth to a calf called K44.

It says in a release that the calf’s mother was born in 1986 and has two siblings, K27 and K34.

Scientists speculated earlier this year that a baby had been born to a member of K pod and said they hoped the whale was female to help the population grow.

CWR says the survival rate of orcas in their first year is 37 to 50 per cent. Research from the University of Washington shows that about 69 per cent of pregnancies among southern resident killer whales fail to produce a live calf. 

The southern resident killer whale population is critically endangered and its numbers have fallen to the low 70s in recent years. K pod is one of three family groups that make up the West Coast’s endangered southern resident killer whale population, along with J and L pod.

The Pacific Whale Watch Association, which represents 29 whale-watching companies in B.C. and Washington state, said in January that 2021 was a record year for whale sightings in the Salish Sea.
