In Canada, Common Murres are found primarily in Atlantic Canada but also occur in smaller numbers along the coast of British Columbia. Population trends vary among colonies but overall, the Canadian population appears to have changed little relative to about 1970. Common Murres are highly susceptible to gillnet fisheries and oil pollution; both of these anthropogenic activities result in significant murre mortality. This species has been identified as a priority for conservation and/or stewardship in one or more Bird Conservation Region Strategies in Canada.

Conservation and management

The incidental catch of seabirds is an important conservation concern with the majority of reported catches involving Common Murre. In the Pacific, salmon gillnets continue to take a heavy toll (Ellis et al. 2013). In Atlantic Canada, gillnet fisheries have been drastically reduced since the 1990s, but mortality from entanglement in nets is still significant (Gaston et al. 2009). Murres are also highly susceptible to chronic and accidental oil pollution. Off the coast of Newfoundland, oiling rates were among the highest in the world (Wiese and Ryan 1999), but have declined since the 1990s (Wilhelm et al. 2009). Still, in light of increasing oil development in Atlantic Canada, the risk of accidental oil pollution is great. Murres have been hunted by residents of Newfoundland and Labrador and by native people for generations. Totals of about 600,000 to 900,000 were shot annually during the 1970s and 1980s, but current levels have been reduced to 200,000 to 400,000 birds. However, murres may also face illegal harvest, which could negatively impact the populations (CWS Waterfowl Committee 2014).

 

Bird Conservation Region Strategies

Environment Canada and partners have developed Bird Conservation Region Strategies in each of Canada’s Bird Conservation Regions (BCRs). In these strategies, selected species are identified either because of conservation concerns (i.e., those species vulnerable due to population size, distribution, population trend, abundance, or threats) or because of stewardship responsibilities (i.e., those species that typify the regional avifauna or have a large proportion of their range or population in the sub-region). Select any of the sub-regions below to view the BCR strategy for that region.
