The energetics of migration and reproduction of dusky Canada geese (Branta canadensis occidentalis)

Creator:: Bromley, Robert G. H.
Abstract:: Adult female Dusky Canada Geese were studied on the Copper River Delta, Alaska and in the Willamette Valley, Oregon during April through July, 1977 to 1979. Objectives of the research were to: 1) determine the chronology of use of protein and energy reserves in relation to four periods of reproduction...

Time budget and habitat use patterns of marbled godwits (Limosa fedoa beringiae) breeding on the Alaska Peninsula

Creator:: Mehall-Niswander, Angela C.
Abstract:: Diurnal time budgets and habitat use patterns of breeding Ugashik marbled godwits (Limosa fedoa beringiae) were studied on the north-central portion of the Alaska Peninsula during spring and summer 1995-1996. Marbled godwits were observed from blinds and behaviors were described for the four phases of the breeding season: pair-formation, egg-laying,...

Site tenacity, mate retention and sexual dimorphism in Black Terns

Creator:: Stern, Mark A.
Abstract:: Between 1982-1984 I studied site tenacity and mate retention in Black Terns at Sycan Marsh, Lake County, Oregon. I banded 778 adult Black Terns and used this marked population to test the hypotheses that site tenacity and mate retention would be less for Black Terns which nest in variable marsh...

Behavioral constraints on harlequin duck population recovery from the Exxon Valdez oil spill in Prince William Sound, Alaska

Creator:: Rizzolo, Daniel J.
Abstract:: I investigated the relationship between harlequin duck (Histrionicus histrionicus) behavior and lack of recovery from the Exxon Valdez oil spill in Prince William Sound, Alaska. First, I evaluated the hypothesis that harlequin ducks in winter have little flexibility to increase foraging time in response to disturbance because they are constrained...

Relations between the distribution of Canada geese and the quantity and quality of forage at W. L. Finley National Wildlife Refuge, 1984-1987

Breeding habitat of harlequin ducks in Prince William Sound, Alaska

Creator:: Crowley, David W.
Abstract:: Breeding habitat of Harlequin ducks (Histrionicus histrionicus) was studied in eastern Prince William Sound, Alaska, during 1991 - 1993. Streams in Prince William Sound were surveyed for Harlequin ducks and monitored with mist nets. Physical characteristics of 24 Harlequin breeding streams were compared to those of 24 streams not used...

Ecology of harlequin ducks in Prince William Sound, Alaska, during summer

Creator:: Dzinbal, Kenneth A.
Abstract:: Harlequin ducks (Histrionicus histrionicus) were observed during the summers of 1979 and 1980 in Sawmill Bay, northeast Prince William Sound, Alaska. Harlequins were associated with a short, medium gradient, non-glacial stream (Stellar Creek) also used by salmon. Although harlequins nested along Stellar Creek, they apparently did not establish home ranges...

Nesting ecology of mallards in the Willamette Valley of Oregon

Creator:: Rickerson, Eric V.
Abstract:: Although widely studied in many portions of North America, little is known about the specific habitat requirements of mallard ducks (Anas platyrhynchos) during the breeding season in western Oregon. I radio-marked 72 female mallards in the Willamette Valley of Oregon in March-April 1995-96 to document wetland habitat selection during pre-nesting...
