“…Approximately two million thick-billed murres feed in Hudson Bay and Hudson Strait, taking 350g fish d-l each (Morrison & Gaston 1986), or 3.5 kg km-*, primarily B. saida with lesser amounts of benthic fish, but G. ogac was not found (Gaston & Noble 1985). Black guillemots in Hudson Bay have similar feeding habits (Cairns 1987).…”

“…King (1969) reported geomorphological analyses of Foley Island, and Bird (1967) classified the coasts of the basin. More recent work includes aerial surveys for birds by Reed et al (1980) and Gaston et al (1986), and a general review of birds of the area by Morrison and Gaston (1986).…”

The Use of Remote Sensing to Evaluate Shorebird Habitats and Populations on Prince Charles Island, Foxe Basin, Canada

ABSTRACT. Landsat-5 Thematic Mapper imagery was used to produce a 17-habitat classification of Prince Charles Island, Foxe Basin, Northwest Territories, through a combination of supervised and unsupervised approaches. Breeding shorebirds and habitats were surveyed at 35 study plots in July 1989. Habitat-specific breeding densities calculated from these observations were used to estimate total populations of breeding shorebirds on the island based on areas of habitat derived from the classified image. Breeding densities were further modelled in two ways: first, to adjust for distance from the coast, where regression analyses found a significant relationship between distance and density, and second, to include only those pixels of areas considered suitable for breeding, using results of a proximity analysis to determine habitat associations between known breeding locations (pixels) and other habitats. Six species of shorebirds were found breeding on Prince Charles Island, with a combined population (after modelling) estimated at 294 000 pairs. Comparison of breeding densities and estimated populations of shorebirds with those recorded at other arctic locations indicated that Prince Charles Island supports highly significant numbers of shorebirds, especially white-rumped sandpipers and red phalaropes. Comparison of reference areas of known habitat with those on the classified image indicated classification accuracy averaged over 90%. Remote sensing appears to offer a reliable method for assessing habitats and regional breeding populations of birds in at least some areas, providing that classification methods are carried out in a carefully controlled manner. Use of the method over broad areas of the Arctic would require considerable work to recalibrate imagery for different geographic regions.

“…The channels between the 'Satellite Islands', as well as Hurd Channel, include sections of open water through most of the year. The time and duration of open water and the availability of suitable breeding sites are some of the factors in determining the distribution of coastal and marine birds (Brown and Nettleship 1981;Morrison and Gaston 1986). In particular, year round open water may be responsible for the large numbers of Black Guillemots in the area, some of which may overwinter here (compare Gaston and McLaren 1990).…”

Birds and marine mammals in southwestern Foxe Basin, Nunavut, Canada

et al. 2007

View full text Add to dashboard Cite

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, bowhead whales and walrus, as well as significant concentrations of shorebirds, common eiders, black guillemots, and perhaps one third of the world's Thayer's gulls. New information was obtained on the status and abundance of these species and novel observations were made on the feeding ecology and breeding phenology of the gulls.
