Monitoring contaminants in gull and tern eggs is a useful tool for gaining insights into local environmental conditions because gulls and terns are integrators of processes occurring at lower levels in the food web and their eggs are generally formed using local food sources. Therefore, the chemical composition of the egg will reflect the chemical characteristics of the region in the vicinity of the breeding colony, including level of contaminants, such as mercury. Eggs are collected any time after laying, ideally well before hatching, but after the full clutch size (3 eggs) has been reached, generally around the middle of June. The collection site is a colony on Lake Mamawi, in the Peace Athabasca Delta; in addition to collection sites outside the park.

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 Great black-backed and European herring gulls . Field data from 1996 to 2015. Many islands in the MANPRC are used by the Great black-backed and European herring gulls for nesting. The presence of this species is 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).

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.

The second largest concentration of common terns (Sterna hirundo) in North America is found on Tern Islands, a set of three small barrier islands separated by water at high tide located within Kouchibouguac National Park. These seabirds are indicators for the condition of coastal, marine, as well as estuarine ecosystems due to the use of these nesting and/or breeding grounds, and their reliance on the distribution of small fish populations in lagoons or along the outer beaches of barrier islands throughout the breeding season. The purpose of the common tern colony monitoring program is to determine the annual total number of nests and estimate mean clutch size in order to evaluate long-term breeding population health. The methods for this measure involve an annual systematic census on Tern Islands over a 1-2 day period in mid-to late June during the late incubation stage.
