Transient Orca Hunting
June is Orca Awareness Month. Orca as apex predators are important in the ecosystem and they are iconic to many of us culturally that live here in British Columbia. Consider ways to help promote their protection and conservation, especially the Southern Resident Orca population which has declined in recent years to approximately 75 individuals.
Here in British Columbia, there are three types of Orca. One type are Transient Orca that feed on seals, sea lions, dolphins, and porpoises. These Orca hunt with stealth and often approach their prey from underneath to either stun or catch the prey. Our cover image shows a Transient Orca catching a harbour porpoise in Puget Sound a few weeks ago. The second type of Orca are Resident Orca that feed on fish, mainly salmon. A third type of Orca (called Offshore Orca) are usually found to the west of Vancouver Island out in the ocean and scientists believe they prey on large ocean fish and sharks.
Along with the usual sightings of many Humpback whales in the area, sightings of Grey whales were reported on four seperate occasions at the end of May and in early June. There were many pods of Pacific White-Sided dolphins that were observed, with the largest pod numbering around 100 members. Rounding our report is a sighting of Dalls porpoise.
The Federal Government (DFO) statement about watching whales in the wild: “To address disturbance in the presence of whales, a mandatory 400-metre vessel approach distance for all killer whales is in effect starting June 1, 2020 in all southern British Columbia coastal waters between Campbell River and just north of Ucluelet. The Marine Mammal Regulations continue to remain in effect year-round, including maintaining a minimum 200 metre approach distance from all killer whales in Canadian Pacific waters other than described above, and 100 metres for other whales, porpoises and dolphins OR 200 metres when the animal is in resting position or with a calf.”

That up-close access might soon end, however, amid community outcry that the crowds in the water have grown too big in recent years and have overwhelmed the spinner pods, chronically disrupting their rest cycles and jeopardizing the population’s long-term survival….
