Protecting Marine Birds

Dr. Caroline Fox, Program Coordinator

The highly productive waters and shores of British Columbia’s coast support an incredible diversity and density of marine life.  Vast numbers of marine birds use these areas for critical activities such as breeding, foraging, wintering and migration.

It is estimated that nearly 6 million individuals from 15 or so seabird species breed locally.  The coast is also a portion of the Pacific Flyway, a major corridor for millions of migratory birds traveling to and from breeding grounds in the Arctic and elsewhere in the continent. Long distance migrants that may breed elsewhere in the world, such as albatrosses and shearwaters, are found offshore in significant numbers.

Conservation Concerns

Marine birds in the Queen Charlotte Basin, BC coast, waters of the Great Bear RainforestDespite their multitudes, many marine bird species on our coast are of great conservation concern. Some marine bird populations are known or are suspected to be experiencing population declines. Major knowledge gaps exist for marine birds at sea, particularly during seasons other than summer and for North and Central coast waters. This lack of information is a serious conservation concern as threats to marine birds are numerous and often interactive.

British Columbia’s marine birds face the following threats:

• chronic and catastrophic oil spills

• oil extraction and development

• food supply change

• fisheries conflict

• contaminants and pollutants

• marine debris

• introduced predators

• wind turbines

• habitat loss, degradation and disturbance

• climate change

Raincoast’s Work

Protecting marine birds through science & advocacy

Bird surveys cover

To address these knowledge gaps, Raincoast undertook extensive at-sea marine bird surveys between 2005  and 2008. We surveyed thousands of kilometers and amassed nearly 20,000 marine bird sightings with over 100,000 individuals counted in more than 70 species.
