Foraging ecology, colony attendance, and chick provisioning of Caspian terns (Sterna caspia) in the Columbia River Estuary

Creator:: Anderson, Scott K.
Abstract:: This study was designed to enhance understanding of factors influencing foraging distribution, diet composition, and overall reproductive success of Caspian terns (Sterna caspia) nesting on East Sand Island in the Columbia River estuary. This colony of nearly 10,000 breeding pairs is of concern to regional resource managers because Caspian terns...

Factors affecting colony size, reproductive success, and foraging patterns of double-crested cormorants nesting on East Sand Island in the Columbia River Estuary

Creator:: Anderson, Cynthia D.
Abstract:: The purpose of this study was to investigate the primary factors affecting colony size, reproductive success, and foraging patterns of Double-crested Cormorants (Phalacrocorax auritus albociliatus) nesting at East Sand Island in the Columbia River estuary, the largest colony of this species on the Pacific Coast of North America. This colony...

Diet and nutrition of breeding canvasback and redhead ducks at Ruby Lake National Wildlife Refuge, Nevada

Creator:: Noyes, James Harry
Abstract:: Diet, nutrition, and foraging strategies of canvasbacks (Aythya valisineria) and redheads (A. americana) were studied by collecting actively feeding birds throughout the reproductive season in 1980 and 1981; samples of available foods were taken each time a bird was collected. Nutrient composition of the aggregate diet was determined for each...

Habitat use, movements, and behavior of postbreeding female canvasbacks in Manitoba

Creator:: Devries, James H.
Abstract:: The habitat use, movements, and behavioral energetics of unsuccessfully breeding female canvasbacks (Aythya valisineria) were examined during the preflightless period in southern Manitoba during 1989-90. Following breeding attempts, unsuccessful females generally expanded their home range on the breeding area, remained there for up to one month, preferentially used large semipermanent...

Life history and environmental influences on avian incubation and parental care in songbirds

Creator:: Austin-Bythell, Suzanne H.
Abstract:: Patterns of nest attendance behavior by breeding birds represent a parent-offspring trade-off in which adults balance self-maintenance with parental care decisions. Incubation, in particular, is of interest because adults must provide an environment suitable for embryonic development through nest-building and contact-incubation. We evaluated how adult incubation constancy and nest visitation...

Humpback Whale (Megaptera novaeangliae) Calling Behavior In Southeast Alaska : A Study In Acoustic Ecology And Noise

Creator:: Fournet, Michelle E. H.
Abstract:: Humpback whales (Megaptera novaeangliae) are a widely distributed baleen whale species, well known for their diverse acoustic behavior. On high-latitude foraging grounds, humpback whales produce a suite of non-song vocalizations (“calls”) in concert with foraging and social behavior. In this dissertation I investigated the role of calls in the acoustic...

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...

Leadership behavior and foraging strategies of a herd of Roosevelt elk inhabiting the Oregon Coast Range

Creator:: Marquez, Monica
Abstract:: A cow-calf herd of Roosevelt elk (Cervus elaphus roosevelti) resident to Indian Creek Research Center (ICRC), Oregon was observed June-August, 1985 and March-August, 1986. Cows at ICRC reproduced in alternate years; cows with calves led the herd a significantly greater number of times than cows without calves (1985, P <...

Response of brood-rearing habitat of sage grouse to prescribed burning in Oregon

Creator:: Pyle, William H. (William Hanson), 1957-
Abstract:: Decline of western sage grouse (Centrocercus urophasianus phaios) in Oregon may be related to the reduced availability of foods in upland sagebrush (Artemisia)-grasslands used for brood-rearing. The goal of this study was to determine primary foods of chicks and the short-term response of brood-rearing habitat to prescribed burning at Hart...
