Red-breasted mergansers (Mergus serrator) are colonial birds found on Tern Islands, a set of three small barrier islands separated by water at high tide located within Kouchibouguac National Park. These piscivorous sea ducks are indicators for the state of the breeding islands and associated marine or estuarine ecosystems, since nest distribution and productivity is closely related to habitat conditions such as the presence of marram grass (Ammophila breviligulata) in addition to sometimes sea lyme grass (Leymus mollis) or common yarrow (Achillea millefolium); while the occurrence of the species is also linked to the scope and abundance of fish resources. The purpose of the red-breasted merganser monitoring program is to determine the annual number of nesting attempts and to measure nest success, as these are important parameters that contribute to breeding population dynamics. The methods for this measure involve an annual census in mid-August where nests (i.e., a bowl with at least one egg) are located by systematically searching the vegetated regions on Tern Islands immediately following the completion of the breeding season.

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.

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.

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.

The piping plover (Charadrius melodus) is a small endangered shorebird listed under the federal Species at Risk Act (SARA). This species uses ocean shorelines as breeding grounds and nests in soft sandy areas with sparse vegetation above the high tide water line. These birds are indicators for the condition of coastal ecosystems due to their critical status; but also since this species is susceptible to human disturbance, habitat loss or alterations, predation, and sensitive to inclement weather related to sea level rise or climate change. The extensive barrier islands within Kouchibouguac National Park host a considerable percentage of the population along the Atlantic Coast therefore our role is crucial in the outcome of this species on a continental scale.

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.

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).

This program assesses demographic parameters and breeding abundance of 5 species of ground (burrow) nesting seabirds: Pigeon Guillemot (Cepphus columba), Rhinoceros Auklet (Cerorhinca monocerata), Glaucous-winged Gull (Larus glaucescens), Leach's Storm-Petrel (Oceanodroma leucorhoa) and Fork-tailed Storm-Petrel (Oceanodroma furcata) at the Seabird Rocks Colony through population counts and capture-mark-recapture techniques. Counts of individuals at the colony are done 3-4 times throughout a breeding season (May-July) to estimate the size of the breeding populations. A banding (capture-mark-recapture) program to estimate annual survivorship of the two storm-petrel species is done via mist-net arrays on two consecutive nights in early May and/or mid-to-late July. This project seeks to track the present status of the ground and burrrow-nesting seabirds on Seabird Rocks and any recovery that may occur due to future habitat restoration and/or predator-control measures.

The abundance of bank swallow (Riparia riparia) nest holes within cliff and bank habitats along PEI National Park coastline is monitored. Previously, large historical colonies were surveyed annually, and every five years a complete census of the entire park shoreline was completed. As of 2010, a complete census is done annually along the coastline of PEI National Park following the breeding season. Nest holes are counted along the coast throughout PEI National Park by multiple observers.
