I’m on my back on the aft deck of Raincoast’s research vessel. My repose is involuntary as we ply the lumpy waters of Haida Gwaii’s west coast. Not one prone to sea-sickness, I nevertheless feel like my head is virtually nailed down, a result of the interminable chop. I have no option but to look skyward and there, to my amazement, are albatrosses, escorting us like some squawking air squadron. For me, the albatross is the grizzly bear of marine birds in terms of its iconicity and, with a wingspan of over seven feet long, commanding physical presence. After experiencing the exhilaration of seeing the largest marine bird on the coast of British Columbia, I immediately reflect on the litany of human-caused hazards facing these majestic pelagics and other marine-bird species. Millions of marine and other coastal birds migrate offshore and along the B.C. coast while millions more breed here. Still others, including the aforementioned albatrosses, are long-distance migrants that breed elsewhere in the world and rely upon our coastal environment and its resources.
This wealth of avian diversity is susceptible to a long list of anthropogenic threats that include oil pollution, climate change, conflict with fisheries and, potentially, wind turbines. In addition, a number of these species are designated as “at risk” by federal and provincial legislation.
Marine birds are abundant, diverse and highly mobile predators and scavengers of the seas. For these and other reasons, marine birds are often used as indicators of ecosystem health and ecosystem change.
The end of 2008 marked the completion of four years of intensive work by Raincoast Conservation to fill basic knowledge gaps regarding seasonal and inter-annual marine bird distribution, density and seasonal shifts in community assemblages in the waters adjacent to the Great Bear Rainforest.
By repeatedly surveying marine waters, from Dixon Entrance to Queen Charlotte Strait and adjacent mainland inlets, Raincoast has documented over 70 species and amassed nearly 20,000 sightings of over 100,000 individual marine and other coastal birds.
Raincoast’s sightings include the more abundant Cassin’s auklet and white-winged scoter to the rare horned puffin and Laysan albatross. Standing out among the many birds observed was the exceedingly rare sighting of a lone, immature short-tailed albatross in the waters southeast of Haida Gwaii. Once numbering in the millions, this species was decimated by the demand for feathers and at one time was thought extinct. Raincoast’s sighting, just one of under 40 reported in B.C. since 1996, highlights the urgent need for longer-term monitoring of marine birds in B.C.’s remote coastal and offshore waters. As such, Raincoast scientists continue to seek to identify areas important for marine birds and examine the potential for conflict with increasing industrial activity, like tanker traffic and wind turbines.

A recent report by the Pembina Institute and Boreal Songbird Initiative, detailed how the Alberta oilsands are killing both birds and their habitat. But the oilsands have the potential to impact avian life far beyond the songbirds and waterfowl migrating through and nesting in Alberta’s boreal forest.
After a two-year lull, Enbridge Inc. has revived their plans to build a twin pipeline from northern Alberta to the B.C. coast. Condensate tankers and oil tankers at least as big as the Exxon Valdez would ply B.C.’s rocky northern coastline on virtually a daily basis, entering Douglas Channel within eyesight of where the 120-metre B.C. ferry Queen of the North struck Gil Island and sank in 2006.
The pipeline would ship over 500,000 barrels of crude oil per day and, twice a week, 350-metre long super tankers would pass by the very spot where the Queen of the North sank as they carry crude to markets in the United States and Asia.
If Enbridge is allowed to construct their proposed dual oil and condensate pipeline joining the oilsands with a marine terminal in Kitimat, then marine birds on the B.C. coast and the ecosystems they depend upon will also be put in significant jeopardy. Birds are generally the most abundant and conspicuous victims of oil-tanker accidents.
Caroline Fox, Raincoast marine bird biologist and University of Victoria PhD student, states that previous scientific reviews indicate that “oil can affect birds in different ways, including plumage and egg oiling, ingestion, and indirectly though ecosystem changes. It’s thought that the primary cause of mortality and stress in oiled birds is fouled plumage, which often results in hypothermia and increased metabolic rates. Ingestion of even small amounts may cause a number of physiological changes or death. Long-term effects are harder to monitor, but may include altered breeding success and survival rates, with potential negative implications for populations.”
Fox also points out that researchers in Canada have estimated that as many as 300,000 seabirds per year are killed off Newfoundland and Labrador due to chronic oil pollution, a figure that is comparable in scale to the estimated mortality following the Exxon Valdez spill in Alaska. Similar to east-coast levels, the relatively high proportion of carcasses reported off the west coast of Vancouver Island that are oiled suggest that chronic oiling is also a concern for B.C.’s marine birds.
A catastrophic Exxon Valdez-like spill would be devastating for the province’s marine-bird populations and the environments they inhabit. In the immediate aftermath of the Exxon-Valdez, it was estimated that several hundreds of thousands of marine birds were killed. Further, after two decades, a number of marine-bird populations have not yet recovered in the areas affected by the Exxon-Valdez disaster.
In an emerging role reversal, the United States now appears to be quickly leaving Canada in its wake in terms of environmental policy. U.S. president Barack Obama has put the brakes on a Bush administration plan to allow drilling off the Atlantic and Pacific coasts, delaying a final decision on the controversial policy for at least six months to give states and stakeholders adequate time to weigh in.
In contrast, taking advantage of government compliancy, Enbridge is moving full speed ahead to convince British Columbians that embracing their “Northern Gateway” pipeline project is in everyone’s best interests. With an enormous war chest, a phalanx of consultants, and a slicker than slick television advertising campaign, website and electronic newsletter, Enbridge is counting on a sophisticated public-relations effort to swamp any opposition to Northern Gateway.
It’s enough to give one pause, as we approach the 20th anniversary of the Exxon-Valdez disaster later this month.

Giving to Raincoast enables you to protect what you love most.
For 25 years, Raincoast has been furthering biodiversity conservation in BC. Thanks to your generous donations, among many other accomplishments, we have been able to end commercial trophy hunting of large carnivores in over 38,000 square kilometers of the Great Bear Rainforest, begin acquiring forest land in order to protect threatened Coastal Douglas-fir ecosystems, aid recovery of endangered Southern Resident killer whales by restoring Chinook salmon habitat, and establish a university research lab dedicated to applied conservation science. Strong partnerships are integral to our success.
Our efforts need to be maintained and advanced, now more than ever. As the biodiversity and climate crises collide, your support allows us to continue to make tangible conservation gains.
Biodiversity protection is the most important gift we can give the next generation. Join us as a Raincoaster today!
