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...

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...

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...

We documented seasonal and daily activity patterns of Common Nighthawk (Chordeiles minor) near Whitehorse, Yukon, to evaluate the appropriateness at higher latitudes of national survey protocols for this species. Nighthawk vocalizations and audible aerial displays were detected at four locations...

We monitored a colony of Cliff Swallows (Petrochelidon pyrrhonota) nesting on an artificial nesting structure that had been built for this species, near the Dezadeash River in Haines Junction, Yukon (60o 44’ 58” N/ 137o 30’ 33” W). We took photographs of the nesting surface of each of the 16...
