Research Spotlight Series: Colonial Seabird Monitoring in Atlantic Canada

By: Sabina Wilhelm, Canadian Wildlife Service Posted April 17, 2018 Editor’s Note: In our Research Spotlight Series we shine a light on exciting research in our province. In this post we showcase the Canadian Wildlife Service. Puffin research on Gull Island (Photo by Pierre Ryan). The Canadian Wildlife Service (CWS) Colonial Seabird Monitoring Program focuses on assessing the population size and trends of 20 species of seabirds across the four Canadian Atlantic provinces, namely Nova Scotia, New Brunswick, Prince Edward Island, and Newfoundland and Labrador.  Over the past year, focus has been on continuing to update the status of major Leach’s Storm-Petrel colonies in the region in light of recent surveys having revealed that several of Newfoundland’s significant colonies, including Baccalieu Island, the world’s largest, have experienced declines of 40-50% over the past 20-30 years. In response to these declines, Bird Life International assessed this species as globally threatened and listed…

Storm-petrels are the most abundant seabird breeding in eastern Canada. They appear at night in dizzying millions at major colonies on our coast. When a species is so prolific, population changes are actually often difficult to detect until they reach crisis proportions – think cod, capelin, caribou. Seabirds are the primary indicators of ocean pollution. They have been the focus of environmental monitoring plans since offshore oil exploration began on the Grand Banks. Under the “regulation” of the Canada-Newfoundland Labrador Offshore Petroleum Board (C-NLOPB), these have been irrelevant paper exercises. The nocturnal Leach’s storm-petrel or carey chick as fishermen refer to them is the most vulnerable seabird to offshore platforms. These tiny robin-sized…
