Evaluating the fatty acid signature technique for studies of diet composition inpiscivorous waterbirds

Creator:: Myers, Anne Mary
Abstract:: This research was designed to evaluate the Fatty Acid Signature (FAS) technique as a non-lethal alternative to more traditional, and sometimes destructive, methods of studying the diet composition of piscivorous birds. Specifically we tested the technique with Caspian terns (Hydroprogne caspia) which currently nest in large numbers in the Columbia...

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...

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...

Foraging ecology of caspian terns and double-crested cormorants in the Columbia River Estuary

Creator:: Lyons, Donald E.
Abstract:: A detailed understanding of the foraging ecology of species preying upon threatened or endangered prey may contribute to identifying and evaluating management options to reduce predation, when such management is deemed appropriate. In the Columbia River estuary, Caspian terns (Sterna caspia) and double-crested cormorants (Phalacrocorax auritus) have been identified as...

Parental care of peregrine falcons in interior Alaska and the effects of low-altitude jet overflights

Creator:: Palmer, Angela G.
Abstract:: To assess the impact of low-altitude jet overflights on parental care, we examined nest attendance, time-activity budgets, and provisioning rates of 21 Peregrine Falcon (Falco peregrinus) pairs breeding along the Tanana River, Alaska in 1995 and 1996. Several intrinsic and extrinsic factors influenced attributes of nesting behavior. Female nest attendance...

Piscivorous colonial waterbirds in the Columbia River estuary : demography, dietary contaminants, and management

Creator:: Suzuki, Yasuko
Abstract:: Caspian terns (Hydroprogne caspia) and double-crested cormorants (Phalacrocorax auritus) nest in large colonies on East Sand Island in the Columbia River estuary, the largest known colonies for the two species in the world. Both species of piscivorous colonial waterbirds have been identified as predators with a significant impact on the...

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...

Bioenergetics-based predator-prey relationships between piscivorous birds and juvenile salmonids in the Columbia River estuary

Creator:: Lyons, Donald E.
Abstract:: This dissertation focuses on the predator-prey relationship between two species of avian predators, Caspian terns (Hydroprogne caspia) and double-crested cormorants (Phalacrocorax auritus), and one of their important prey types, juvenile salmonids (Oncorhynchus spp.), in the Columbia River estuary of Oregon and Washington states during the period 1998 – 2007. I...

Effects of diet and crude oil ingestion on growth and biochemistry of captive-reared pigeon guillemots (Cepphus columba)

Creator:: Hovey, Andrew K.
Abstract:: The pigeon guillemot (Cepphus columba) population in Prince William Sound has failed to recover from declines that occurred both before and after the Exxon Valdez Oil Spill (EVOS). Post-spill studies of pigeon guillemot breeding biology have identified three potential factors limiting recovery: (1) predation on eggs and nestlings; (2) declines...

Breeding and foraging ecology of Caspian terns (Sterna caspia) in the mid-Columbia River : predation on juvenile salmonids and management implications

Creator:: Antolos, Michelle
Abstract:: I investigated Caspian terns (Sterna caspia) breeding at colonies on the Columbia Plateau (southeastern Washington and northeastern Oregon), with emphasis on the breeding and foraging ecology of Caspian terns nesting at colonies in the mid-Columbia River. I focused research at colonies where Caspian terns foraged on juvenile salmonids (Oncorhynchus spp.)...
