Seasonal patterns of prey availability and the foraging behavior of arctic foxes (Alopex lagopus) in a waterfowl nesting area
Alice Stickney
1991, Canadian Journal of Zoology (69) 2853-2859
The foraging behavior of arctic foxes was observed in a waterfowl nesting area on the Yukon–Kuskokwim Delta of Alaska in 1985–1986. Observations were made during peak fox activity from two towers, 3 m high, located in different community types. Data were collected continuously for individual foxes on specific activities, the community...
Evidence for color phase effects on the breeding and life history of Northern Fulmars
Scott A. Hatch
1991, The Condor (93) 409-417
About 15% of Northern Fulmars (Fulmarus glacialis) breeding on the Semidi Islands in 1979 had light-phase plumage; the remainder were dark. Fulmars of different plumage types mated indiscriminantly, but the lighter member of a mixed pair was more likely to be male than female. Pairs that included at least one...
Mortality of seabirds in the Japanese land-based gillnet fishery for salmon
Anthony R. DeGange, Robert H. Day
1991, The Condor (93) 251-258
Mortality rates of seabirds in the Japanese land-based drift gillnet fishery for salmon were assessed from 413 gillnet sets made by Japanese research vessels in offshore areas used by the commercial fleet. Sixteen species of seabirds were recorded in nets. Shearwaters, primarily Short-tailed Shearwaters (Puffinus tenuirostris), and to a lesser...
Observations on habitat use, breeding chronology and parental care in Bristle-thighed Curlews on the Seward Peninsula, Alaska
Robert E. Gill Jr., Richard B. Lanctot, J.D. Mason, Colleen M. Handel
1991, Wader Study Group Bulletin (61) 23-36
Results from an intensive survey in 1989 of one of the two known breeding localities of Bristle-thighed Curlews Numenius tahitiensis are reported. During the pre-nesting period birds confined most of their activity to two vegetation communities: shrub meadow tundra and low shrub/tussock tundra. During nesting more than half the Curlews...
Energy dynamics, foraging ecology, and behavior of prenesting greater white-fronted geese
D.A. Budeau, John T. Ratti, Craig R. Ely
1991, Journal of Wildlife Management (55) 556-563
We collected greater white-fronted geese (Anser albifrons frontalis) on their nesting grounds on the Yukon-Kuskokwim Delta, Alaska, when they arrived and again before incubation during 1986 and 1987. Body mass, water content, crude fat, and crude protein increased in female geese between arrival and incubation onset in 1986 and 1987...
Notes on longevity and flightlessness in bristle-thighed curlews
J.S. Marks, R. L. Redmond, P. Hendricks, R. B. Clapp, Robert E. Gill Jr.
1990, The Auk (107) 779-781
Bristle-thighed Curlews (Numenius tahitiensis) are among the least-studied shorebirds in the world. They have a highly restricted breeding range in western Alaska and winter exclusively on remote islands in the central and south Pacific (AOU 1983, Kessel 1989). The status of these birds is not known, but they are...

Magnetic models for the United States for 1985
Norman W. Peddie, Audronis K. Zunde
1990, Circular 1039
New models describing the magnetic field in the United States at the beginning of 1985 and the rate of change expected during the next few years have been developed. The models--which will serve as the basis for a new set of magnetic charts--were derived from several tens of thousands of...
