Leslie Tuck and the Origins of Arctic Marine Bird Research in the Canadian Arctic, 1954 – 1957
Leslie M. Tuck (1911 – 79) was a pioneer of Arctic ornithology. He made the first studies in Canada of the breeding biology of Arctic-breeding seabirds, making three visits to major seabird colonies (four colonies total at the three destinations) in the Eastern Arctic in the 1950s. His main purpose was to assess population sizes and demography of Thick-billed Murres. His aims were to better understand the impact of hunting in Newfoundland and Lab…
A Review of Thick-Billed Murre Banding in the Canadian Arctic, 1950–2010
Banding of Thick-billed Murres Uria lomvia in the Canadian Arctic was initiated by L.M. Tuck in the 1950s, when he visited three of the largest breeding colonies in Canada. Up to 2010, banding had been carried out at eight of the 10 major breeding colonies, with totals of more than 1000 birds banded at Coburg Island and Cape Hay, Bylot Island, in the High Arctic and at Digges Sound and Coats Island in northern Hudson Bay. Because murres are long-…
Birds and Mammals of Prince Leopold Island, Nunavut, 1975–2012
Prince Leopold Island is the most important marine bird colony in the Canadian High Arctic. An Environment Canada research camp on the island was occupied for varying periods (mean 37 days) during 18 summers from 1975 to 2012. Research concentrated on the biology of the marine bird colonies, but incidental notes were kept on other sightings of birds and mammals. Forty-seven species of birds, of which 12 bred, six species of terrestrial mammals, f…
Effects of Climate-Induced Changes in Parasitism, Predation and Predator-Predator Interactions on Reproduction and Survival of an Arctic Marine Bird
A detailed understanding of the processes and interactions within biological communities is needed to describe and predict the biological consequences of climate change. Global warming may affect biological communities at specific sites through changes in the species composition that follow changes in range, or through altered food web interactions caused by changes in phenology or behaviour. We describe the demographic consequences for a colonia…
Sources of Breeding Season Mortality in Canadian Arctic Seabirds
In more than 30 years of studies on marine birds in Arctic Canada, we have observed numerous instances of mortality of adults, eggs, and chicks that seem unusual when compared to known sources of mortality for seabirds breeding in temperate or tropical regions. The extreme cold weather and ice conditions of the Arctic might intuitively be expected to be a significant factor in mortality for these Arctic birds. While weather conditions led directl…
Status, Trends and Attendance Patterns of the Northern Fulmar Fulmarus glacialis in Nunavut, Canada
Nunavut supports ten breeding colonies of northern fulmars (Fulmarus glacialis), most of which have rarely been visited on the ground by biologists. During 2000–04, we surveyed six colonies previously thought to support more than 80% of the Canadian Arctic population, which was believed to number about 300 000 breeding pairs. Our counts suggested that the breeding populations of some colonies, especially those at the largest colonies, Cape Searle…
Status of High Arctic Black-Legged Kittiwake ( Rissa tridactyla ) Colonies in Barrow Strait, Nunavut, Canada
We used aerial survey estimates, photographic censuses, and plot counts to examine trends in the size of five black-legged kittiwake (Rissa tridactyla) colonies around Barrow Strait, eastern Nunavut, Canada, between 1972 and 2007. During these three decades, one small colony disappeared, two medium-sized colonies showed no overall trend, and one moderate and one large colony appeared to increase in size. Collectively, the number of kittiwakes bre…
Factors Influencing Colony Attendance by Northern Fulmars in the Canadian Arctic
The northern fulmar (Fulmarus glacialis) is a common seabird of the North Atlantic Ocean and marine areas of eastern Nunavut. We studied attendance patterns of fulmars at two colonies in the Canadian High Arctic to assess variation in attendance at high latitudes, to compare these patterns to those found for fulmars breeding at colonies to the south, and to determine how weather conditions and breeding status might influence attendance. Colony at…
Birds and marine mammals in southwestern Foxe Basin, Nunavut, Canada
The southwestern part of Foxe Basin is a little known region of the Canadian Arctic, being difficult to access during the summer because of heavy and unpredictable ice conditions. Surveys of birds and marine mammals in the area were carried out by lightweight expeditions in the summers of 1994 and 1995, using sea-kayaks, as well as a Peterhead boat from the nearest community, at Repulse Bay. The area supports important populations of narwhal, bow…
Trends in Forage Fish Populations in Northern Hudson Bay since 1981, as Determined from the Diet of Nestling Thick-billed Murres, Uria lomvia
Trends in the composition of nestling thick-billed murre diets were analyzed for the period 1980-2002 on the basis of observations of food delivered to nestlings at two breeding colonies in northern Hudson Bay. The incidence of arctic cod, sculpins, and benthic Zoarcidae decreased and the incidence of capelin and sandlance increased over the period considered. Arctic cod fell from a mean of 43% of deliveries in the mid-1980s to 15% in the late 19…
Birds and Mammals of Coats Island, N.W.T
We summarize records of birds and mammals obtained at Coats Island, Northwest Territories during one visit by a National Museum of Natural Sciences expedition and fourteen visits by Canadian Wildlife Service field crews to the northeast corner of the island, as well as records obtained from the journals of the Hudson's Bay Company post active on the island from 1920 to 1924. The terrestrial mammal fauna is very depauperate, lacking any small herb…
Peat Deposits and Thick-billed Murre Colonies in Hudson Strait and Northern Hudson Bay
Deposits of peat moss are found in association with several major seabird colonies in the area of Hudson Strait and northern Hudson Bay. Because such deposits are absent from similar ground away from seabird colonies, they seem to have developed as a result of manuring by the birds. Consequently dates for the base of the peat provide minimum dates for the establishment of bird colonies. Dates obtained at three colonies suggest that they were esta…
The Distribution of Larger Species of Birds Breeding on the Coasts of Foxe Basin and Northern Hudson Bay, Canada
Aerial surveys of large birds on the coasts of Foxe Basin and northern Hudson Bay were carried out in late June and early July in 1979, 1983 and 1984. Greatest numbers of birds were seen along low-lying coasts backed by wet lowland tundra, particularly where these merged into extensive inter-tidal flats. These areas have emerged from the sea only during the past 2000 years. Even in areas of wet lowland tundra, all species except jaegers appeared …
Phenotypic Variation among Thick-billed Murres from Colonies in Hudson Strait
Thick-billed Murres (Uria lomvia) breeding in the Canadian Arctic are restricted to a small number of colonies, all comprising more that 10,000 pairs. Five of these colonies are scattered through Hudson Strait. We collected adult breeders at three of the colonies - Digges Island, Hantzsch Island, and Akpatok Island - and compared wing and bill measurements and body weights to look for inter-colony differences. Significant inter-colony differences…
