Supplemental feeding influences reproductive success of the Hawaiian goose (Branta sandvicensis) at Haleakala National Park, Maui, Hawai'i

Creator:: Tamayose, Joy
Abstract:: Low reproductive success has been typical of high elevation populations of the Hawaiian goose (Branta sandvicensis) or nēnē. Researchers identified predation and inadequate nutrition as limiting factors. Reproductive success remained low in most years despite on-going predator control programs. I used a supplemental feeding program over two breeding seasons in...

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...

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...

Bird community patterns of spring-seasonal and semi-permanent wetlands in the Sacramento Valley, California

Creator:: Harris, P. Dawn
Abstract:: Freshwater wetlands in the Sacramento Valley provide breeding, wintering, foraging and stopover habitat for migratory and resident birds. With a loss of 95% of historic freshwater wetlands, the restoration of wetlands on private land could provide important habitat for birds. Documentation and monitoring of bird use on previously restored wetlands...

Harlequin duck demography during winter in Prince William Sound, Alaska : effects of the Exxon Valdez oil spill

Creator:: Esler, Daniel
Abstract:: The 1989 Exxon Valdez oil spill was a major perturbation of nearshore habitats of Prince William Sound, a wintering area for harlequin ducks (Histrionicus histrionicus). This research was designed to evaluate harlequin duck population recovery from the oil spill from 1995 to 1998, using a demographic approach to assess both...

Ecology of female northern pintails during winter in the San Joaquin Valley, California

Creator:: Fleskes, Joseph P.
Abstract:: I radio-tagged 191 Hatch-Year (HY) and After-Hatch-Year (AHY) female northern pintails (Anas acuta) in the San Joaquin Valley (SJV), California and studied their movements, habitat use and survival during August March, 1991-94. Overall, 94.3% wintered in central California; the highest percentage left during the 1991 drought. Tulare Basin and Mendota...

Habitat availability, dietary mineral supplement, and measuring abundance of band-tailed pigeons in western Oregon

Creator:: Sanders, Todd Alan
Abstract:: My objectives were to: 1) develop a point count technique for estimating relative abundance of band-tailed pigeons (Columbafasciata monilis), 2) determine the availability, distribution, and interspersion of mineral sites, and nesting and foraging cover in relation to abundance of band-tailed pigeons in west-central Oregon, and 3) test the hypothesis that...

Nesting and foraging ecology of band-tailed pigeons in western Oregon

Creator:: Leonard, Jerome Patrick
Abstract:: Pacific Coast band-tailed pigeons (Columba fasciata) have declined markedly during the past several decades. Despite implementation of increasingly restrictive hunting regulations, populations have shown minimal signs of recovery. I radio-marked 127 adult band-tailed pigeons in the central Oregon Coast Range in April-May of 1993-95 to document nesting chronology and productivity,...

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,...

Habitat use and productivity of harlequin ducks in the central Cascade Range of Oregon

Creator:: Bruner, Howard J.
Abstract:: The specific habitat requirements of harlequin ducks (Histrionicus histrionicus Linnaeus 1758), which breed in the Pacific Northwest, are largely unknown. I captured and attached radio transmitters to 42 female harlequins (36 paired and 6 unpaired) in the central Cascade Range of Oregon in 1994 and 1995. Breeding pairs used 3rd...
