St. Helena Island supports nationally significant populations of northern fulmar (Fulmarus glacialis), Thayer’s gull (Larus thayeri) and High Arctic brant (Branta bernicla hrota), as well as locally important numbers of other species including common eiders (Somateria mollissima borealis) and...

Waterfowl and waterbird populations were monitored in wetlands and ponds along the highway corridors in the southern Yukon between 1991 – 2016. Approximately 200 wetlands were surveyed once a week for a period of 5 weeks beginning in early May (1991 – 2014); the survey period was reduced to 4...

The Point Lepreau Bird Observatory (PLBO), located in Point Lepreau, New Brunswick, was created as a project of the Saint John Naturalists’ Club (SJNC) in late 1995. The SJNC began accumulating data on bird migration through the Bay of Fundy in spring and fall in 1996. Migration data are...

Aerial surveys were performed in the Rasmussen Lowlands, Nunavut, to determine the numbers and distribution of Greater White-fronted Geese and other waterfowl species. Surveys were carried out in the Lowlands from 20-24 June 1994 and 20-25 June 1995. The survey procedure included flying straight...

This bird monitoring program uses both traditional point counts and audio recordings to detect changes and trends in the relative abundance and community composition of a suite of forest bird species within Nahanni National Park Reserve. The intent of this study is to provide an early warning of...

Georgian Bay Islands National Park uses point counts to monitor forest birds on Beausoleil Island; this measure focuses on the abundance of five common songbird species and overall diversity.

The presence and abundance of 11 marsh birds are assessed through visual and audio surveys twice every year (8 plots/year) throughout the park between May and July. Bird species richness and abundance of indicator species can be compared with hundreds of other Marsh Monitoring Program sites...

"Birds are the most diverse of land vertebrates and are an important indicator of ecosystem health. Large protected areas, such as Banff National Park, provide important habitat for a wide range of bird species. Data collected can provide a number of ecological indices; for example, used to...

The Rusty Blackbird (Euphagus carolinus) breeds in boreal forest wetlands across North America, and winters in the southeastern USA. This species is listed under Canada’s Species at Risk Act as Special Concern due to population declines. For the study, 1220 Rusty Blackbirds were captured in...

We conducted a species-specific survey for Common Nighthawk (Chordeiles minor) near the northwestern limit of the species’ breeding distribution, in order to investigate relative abundance and also to determine whether a species-specific survey protocol being established for Canada would be...
