Common Eider ( Somateria mollissima v-nigrum ) Nest Cover and Depredation on Central Alaskan Beaufort Sea Barrier Islands
Female common eiders (Somateria mollissima v-nigrum) generally select nest sites in areas with driftwood cover. Previous studies of common eiders have shown a positive relationship between nest success and driftwood cover. Our observations led us to hypothesize that cover does not enhance nest success when mammalian predators are present. To evaluate nest cover selection in common eiders, we examined five years of nesting data to determine the in…

Oilfield Development and Glaucous Gull (Larus hyperboreus) Distribution and Abundance in Central Alaskan Beaufort Sea Lagoons, 1970–2001
We evaluated aerial survey data for glaucous gulls (Larus hyperboreus) in central Alaskan Beaufort Sea lagoons near the Prudhoe Bay oilfields during June to September 1978– 2001 for trends in numbers of glaucous gulls, associations with human activity, and confounding relationships with environmental variables. Most glaucous gulls were in barrier island and mainland shoreline habitats, and the total number of gulls per survey ranged from 50 to 16…
Response to Letter by Richard B. Lanctot and Jeffrey S. Gleason
To be clear, we are not advocating the view that glaucous gull numbers or nests have increased or remained stable during the period studied, nor are we suggesting that oilfield development has affected important population parameters of glaucous gulls. Rather, our primary goal of this letter was to suggest that the data used by Noel et al. to assess potential effects of oilfield development on glaucous gull distribution and abundance appear to la…
The Status of Biological Research in the Russian Arctic
Research and the protection of nature in the Russian Arctic traditionally were carried out in the system of state nature reserves (Zapovedniks) and biological stations. As mentioned earlier, Russian state support of nature reserves and national parks has declined dramatically in recent years. Nevertheless, 11 Nature reserves currently exist in the Russian Arctic. Some of these reserves were recently established with financial support from the Ger…
Distribution and Movements of Brood-rearing Lesser Snow Geese in Relation to Petroleum Development in Arctic Alaska
Environmental scientists were concerned that construction of the Endicott Project in the outer Sagavanirktok River delta, east of Prudhoe Bay, Alaska, would obstruct brood-rearing movements of Alaska's largest established nesting population of lesser snow geese (Chen caerulescens caerulescens). During 1980-84, prior to the Endicott Project, the distribution of snow goose flocks during the brood-rearing period was generally less than 5 km from the…
Staging and Wintering Areas of Snow Geese Nesting on Howe Island, Alaska
From July 1980 to July 1990, leg bands were put on 4556 adults, subadults, and goslings from the lesser snow goose (Chen caerulescens caerulescens) colony (~1000 nesting birds) on Howe Island, near Prudhoe Bay, Alaska. In addition, 1431 neck bands were put on 1714 of the leg-banded adults and subadults. During the period from September 1980 through May 1991, 3244 discrete, within-year resightings and recoveries were received of neck-banded and le…
Late-Summer Abundance and Distribution of Marine Birds in Kasegaluk Lagoon, Chukchi Sea, Alaska
Oil and gas drilling programs in the Alaska Chukchi Sea were carried out on leases offshore from Kasegaluk Lagoon in 1989-91, and further exploration and development activities in this area are likely in future years. We conducted aerial surveys between late July and early September 1989-91 to determine the distribution and abundance of marine birds in the Kasegaluk Lagoon area. We hypothesized that Kasegaluk Lagoon supported an avifauna similar …
Observations of Thick-billed Murres ( Uria lomvia ) and Other Seabirds at Cape Parry, Amundsen Gulf, N.W.T
The Thick-billed Murre colony near Cape Parry, Northwest Territories, Canada, is the only murre colony in the western Canadian Arctic and is isolated to a greater extent than any other murre colony in the world. We conducted a brief but intensive survey of this colony on 1 and 2 August 1979 and recorded over 700 Thick-billed Murres, 16 Black Guillemots and 2 Common Murres. Some murre eggs were seen on the cliffs but a reliable measure of producti…
Waterbird Migration Near the Yukon and Alaskan Coast of the Beaufort Sea
Westward moult migrations of seaducks were studied in the summers of 1972 and 1975 (northern Yukon) and 1977-78 (west of Prudhoe Bay, Alaska). Methods used were visual observations from the coast, aerial surveys, and (in 1975) DEW radar. Many male Oldsquaws (Clangula hyemalis) fly west near the north coast of Alaska in early July. Most seem to travel only a short distance; tens of thousands subsequently moult in various lagoons along northern Ala…
The Dovekie, Alle alle , as a Spring Migrant in Eastern Lancaster Sound and Western Baffin Bay
The distribution and numbers of dovekies during spring migration were studied by aerial surveys of eastern Lancaster Sound (1976, 1978, 1979) and western Baffin Bay (1978, 1979). Dovekies that nest in northwest Greenland migrated north through the study area during May. Extrapolations of recorded densities indicate that a peak of ~14 million dovekies may have been present in eastern Lancaster Sound and northwest Baffin Bay in mid-May 1978: fewer …
Waterbird Migration Near the Yukon and Alaskan Coast of the Beaufort Sea
Radars, systematic visual observations from the coast, and aerial surveys were used to study migration near the Yukon (1975) and Alaskan (1977-78) coasts of the Beaufort Sea. Conspicuous eastward migration of loons, brant, seaducks, jaegers and glaucous gulls occurs along the icebound coast, and in the Yukon some eastbound species (especially brant) concentrate coastally. Overall, however, eastward migration is predominantly broad-front with litt…
Fall Observations of Westward Migrating White Whales ( Delphinapterus leucas ) Along the Central Alaskan Beaufort Sea Coast
it appears that at least a portion of the westward fall migration by white whales out of the southeastern Beaufort Sea occurs during mid-to late September near the coast, well south of the southern edge of the pack-ice, but seaward of the barrier islands
