Erich Hoyt, who has been enjoying adventures with killer whales and other sea creatures since the early 1970s, will share his understanding of the underwater world during a series of presentations from British Columbia to Northern California.

The tour begins today on Saturna Island in British Columbia. For the full schedule, visit The Whale Trail website.

Erich has a rare talent. He is both an engaging writer as well as an experienced scientific researcher. His first book, “Orca: A Whale Called Killer,” is essential reading for orca supporters. His understanding of the oceans has led him into the field of conservation, seeking greater protections for marine habitats throughout the world.

As Erich prepared for his upcoming tour, sponsored by The Whale Trail, I had the privilege to visit with him for more than an hour via Skype from his home in Bridport, England.

We discussed how people’s attitudes in the U.S. and Canada have changed since 1973. That was when Erich’s curiosity was sparked by encounters with Northern Resident orca pods in British Columbia, where he had moved from the U.S. with his family.

Those were the days when little was known about killer whales. Orcas were still being captured in the Northwest and sent to aquariums throughout the world. Since then, we have learned how those first captures had a serious effect on the close-knit orca communities. Continuing threats today include pollution and a lack of chinook salmon, the primary prey of orcas.

In 1999, Erich helped start a research program in Russian to bring the same kind of scientific scrutiny and conservation concerns to killer whales on the opposite side of the ocean. That program, involving Russian scientists, revealed the presence of two types of orcas, those that eat marine mammals and those that eat fish — similar to what we call “transients” and “residents” in the Northwest.

Orca communities identified so far in Russia range in size from 50 to 600 animals. As we’ve seen in the Northwest, cultures — such as vocal dialects and feeding habits — are handed down from mother to offspring.

An awareness of orcas, as seen in the U.S. and Canada, has not reached Russia or many places in the world, Hoyt says. Russia still allows killer whales to be captured, and last year seven orcas were taken from the Sea of Okhotsk. Earlier captures in Russia were especially disheartening to the researchers who had come to know the individual animals taken from their families.

During his presentation, Erich will show a brief video of some of the Russian capture efforts.

In countries such as Russia, China and Japan, new marine aquariums are being built all the time, with orcas and beluga whales as the star attractions. That’s in stark contrast to the situation in the U.S., where a growing awareness of wild orcas along with the film “Blackfish” has helped change people’s attitudes about keeping large marine mammals in captivity.

Erich told me that he would like to see more people around the world come to know individual orcas by name, as we do here in the Northwest.

“Look at how far things have come, from when we didn’t know anything about them to when we start to see them as our friends,” he said.

About a week ago, I reported that NOAA Fisheries had undertaken a yearlong review to determine if the “critical habitat” for Southern Resident killer whales should be extended down the Washington and Oregon coasts. See Kitsap Sun, April 24 (subscription). A special consideration for protecting the whales from undue noise was part of the petition from the Center for Biological Diversity.

Hoyt agreed that sound should be given special consideration by the federal government.

“Rob Williams (a Canadian researcher) talks about acoustic refuges,” Erich noted. “It is a challenging issue, because whales and dolphins can hear so well… We will need much larger marine protected areas if we really want to protect them…”

A general increase in noise levels in the ocean can lead to habituation by marine mammals, he noted. As they grow accustomed to louder sounds, the animals may adjust — but how will that affect their ability to communicate and find prey? What are the prospects for their long-term survival under more noisy conditions?

And then there is the special issue of mid-frequency sonar, which can cause temporary or even permanent hearing loss for some species. Navies that use sonar must be extra careful to avoid impacts, he said.

Erich and I also talked about L-112, the young female orca that washed up dead near Long Beach about the time the Royal Canadian Navy was conducting exercises far to the north. Investigators were unable to determine what caused the “blunt-force” injury to the animal. But they ruled out explosives being used by the Navy, because the currents were in the wrong direction and the distance was too great.

“This brings to mind the crash of the Malaysian jetliner,” Erich said. “You know something unusual happened, but it defies almost any explanation you bring up. Scientists tend to come up with explanations that are the simplest … but they should be careful not to rule anything out.”

Killer whale researcher Ken Balcomb has suggested that L-112’s mother may have carried her dead daughter to the area where she was found. Hoyt said he has personally observed a female white-sided dolphin carrying her dead offspring for more than two hours in Northern Japan.

“It was really touching. We didn’t know at first if the baby was dead. We were not very close. But eventually the mother just let go of the baby.”

Erich expects mixed audiences at his upcoming appearances — from people who know more about certain issues than he does to people who are dragged to the event by a friend.

One message will be that people can watch whales from shore without causing them any disturbance. That’s the mission of The Whale Trail, the organization sponsoring Erich’s trip to locations where killer whales may be seen from shore.

I told Erich about my first adventures with killer whales during the fall of 1997, when 19 orcas visited Dyes Inlet. See “The Dyes Inlet Whales 10 Years Later.” One of my messages at that time was to encourage people to watch from vantage points in Tracyton, Chico and Silverdale.

“Land-based whale watching is really close to my heart,” Erich told me. “It’s the kind of thing that’s important for the community … and a fantastic way to get to know wildlife.”

Hoyt’s appearances in Washington state include this Wednesday in Port Townsend, Thursday in Port Angeles and May 18 in Seattle. Visit The Whale Trail website for the full schedule.
