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.

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.

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.
