A Whale of an Update

Scientists and non-scientists alike have made significant progress in our understanding and appreciation for killer whales (orca).

Highlights

Many wonderful events have occurred in the past few years to enhance our understanding of killer whales. As a result, changes in how humans interact with whales is continually improving. Here are a few recent examples:

January 2018 – The Vancouver Aquarium announced it will no longer keep whales and dolphins in captivity. The change will allow them to focus efforts on the Aquarium’s research and conservation work. Part of this effort is the The Marine Mammal Rescue Centre which cares for marine mammals found injured, ill or abandoned, until they can be returned to their natural habitats.

In 2016, California passed a law that outlawed breeding orcas and holding them in captivity for “display, performance, or entertainment purposes”. Florida is now seeking to pass a similar measure.

Baby Whales

Newborn orcas are around 2 meters long and weigh approximately 150 kg. For the Southern Residents, 8 new baby orca introduced themselves in 2015 and 2016 with no new orca births in 2017. These births were offset by 10 deaths in this same timeframe bringing the total number of Souther Resident whales to 76. See Southern Resident population statistics here.

For the Northern Residents, their community is comprised of three clans A, G and R, with a total of 16 pods and 33 matrilines. The population continues to show healthy growth and as of 2014, the population numbered 290 individuals and had experienced an average annual growth rate of 2.2% over the past 40 years.  Growth chart is from the research report (Towers et al.2015). The Vancouver Aquarium’s Adopt a Whale website has a full list of the Northern Resident whales and matrilines.

Awesome Video Footage

Chris Wilton’s Youtube video of a chance sighting of Northern Resident Orcas rubbing their bellies on a beach directly in front of him and his friends was a viral hit with over 1.5 million views and counting.

Marine Detective, Jackie Hildering, wrote a great blog post to explain more about this specific event identifying the whales and explaining this unique whale behaviour.

Improved Websites and Collaborations

Explore.org added OrcaLab’s live camera feeds to their website. The network of underwater microphones, known as hydrophones, cover 50 square kilometers (20 square miles) of core orca habitat on British Columbia’s west coast. As a bonus feature visitors can sign up for text alerts (on the left hand side as you scroll down the explore.org page), which will send notifications when the orcas are active.

Reference Materials

Researchers and non-profit organizations provided comprehensive new guides to track, identify and report on whale populations. The following reports are available online:

Citizen Reporting Network

In addition to the fantastic work by professional research, The B.C. Cetacean Sightings Network (BCCSN) has developed a platform for everyone to provide information they have about whales. In 2015 they added a free mobile app called WhaleReport to make it easy for anyone to collect and report sightings.

The network has over 4,300 observers across British Columbia, ranging from whale watching operators, lighthouse keepers, researchers, or even recreational boaters gathering data on the occurrence of whales, dolphins and porpoises in BC waters. Throughout the year the BCCSN presents to thousands of British Columbians at schools, community groups, professional associations and festivals.
