Colonial Waterbird Health and Contaminants

This dataset contains metals, including total mercury levels, stable nitrogen isotope values, polycyclic aromatic hydrocarbons, and polychlorinated dibenzodioxin (PCDDs) and polychlorinated dibenzofuran (PCDFs) levels in eggs of seven species of colonial waterbirds (California Gull, Franklin’s Gull, Herring Gull, Ring-billed Gull, Caspian Tern, Common Tern and Forster's Tern). Data are available for 1977, 2009, and 2011 – 2015 for sites located in the Peace-Athabasca Delta/western Lake Athabasca. Geographic coverage was expanded in 2014 and 2015 to include additional egg collection sites across Alberta, Saskatchewan, and the Northwest Territories. While no applicable guidelines exist for these measurements, our expert assessment is that the observed levels of mercury are not likely to pose a risk to these bird populations.

Aquatic bird eggs are being collected for contaminants analysis. Egg collections in the Peace-Athabasca Delta area support Parks Canada’s activities at Wood Buffalo National Park and the multi-stakeholder Peace-Athabasca Ecosystem Monitoring Program. This monitoring activity employs repeated censuses of birds and builds on initial egg collections made in 2009 from Egg Island (Lake Athabasca) and Wood Buffalo National Park, with the goal of evaluating contaminant burdens, contaminant sources and changes in sources through time. Egg samples are collected from colonial waterbirds California Gulls (Larus californicus), Herring Gulls (Larus argentatus), Ring-billed Gulls (Larus delawarensis), Caspian Terns (Hydroprogne caspia) and Common Terns (Sterna hirundo) and insectivorous birds Bank Swallows (Riparia riparia), Cliff Swallows (Petrochelidon pyrrhonota) and Tree Swallows (Tachycineta bicolor) to monitor health and contaminant levels of aquatic and terrestrial birds in the oil sands region and in reference areas.

These fish-eating colonial waterbirds breed and nest in colonies on islands in and around Fathom Five National Marine Park. Five species of colonial waterbird are monitored. These birds and their eggs are effective measures of environmental contamination and aquatic ecosystem health.

Monitoring of the number of eggs and nests for the tern. Field data from 1992 to 2019. Many islands in the MANPRC are used by the terns for their nesting. The presence and great abundance of this species are characteristic of the inland ecology of the park.

Herring gull (Larus arentatus, HERG), great blue heron (Ardea Herodias GBHE), double-crested cormorant (Phalacrocorax auritus, DCCO) and ring-billed gull (Larus delawarensis, RBGU) have been monitored in Pukaskwa National Park since 1977 as part of the colonial waterbird monitoring program. A complete count of active nests on islands found along the ~120km of coast of Pukaskwa is conducted based on the Canadian Wildlife Service (CWS) protocol. The nest count is carried out during the peak of breeding over a period of 2-3 weeks. From 1977 – 1981, surveys were conducted annually and used an island numbering system (Old Colony Number in datasheet).
