Marine habitat use of black-footed and Laysan albatrosses during the post-breeding season and their spatial and temporal overlap with commercial fisheries

Creator:: Fischer, Karen Naess
Abstract:: Incidental bycatch in commercial fisheries has been identified as a threat to black-footed albatrosses (Phoebastria nigripes) and Laysan albatrosses (P. immutabilis). Effective long-term conservation of these albatrosses necessitates a thorough understanding of their marine distribution, which marine habitats are selected during foraging, and where they are most likely to interact...

Breeding ecology and nest site selection of Kittlitz's murrelets on Kodiak Island, Alaska

Creator:: Lawonn, Matthew James
Abstract:: The Kittlitz's murrelet (Brachyramphus brevirostris) is a rare member of the seabird family Alcidae that breeds in coastal areas of Alaska and Beringian Russia. The species belongs to the genus Brachyramphus, an unusual seabird taxon in which all three extant species nest non-colonially, situating their nests up to 75 km...

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...

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...

Extrinsic and Intrinsic Factors Associated with Reproductive Success of Caspian Terns (Hydroprogne caspia) at East Sand Island, Columbia River Estuary

Creator:: Bailey, Olivia A.
Abstract:: Declines in wild salmonid (Oncorhynchus spp.) populations in the Columbia River basin have resulted in managers identifying that avian predation on juvenile salmonids is an important limiting factor for salmonid recovery. Caspian Terns (Hydroprogne caspia), particularly those nesting in the Columbia River estuary, were identified as key avian predators that...

Site fidelity and colony dynamics of Caspian terns nesting at East Sand Island, Columbia River Estuary, Oregon, USA

Creator:: Collar, Stefanie
Abstract:: Fidelity to breeding sites in colonial birds is an adaptive trait thought to have evolved to enhance reproductive success by reducing search time for breeding habitat, allowing earlier nest initiation, facilitating mate retention, and reducing uncertainty of predator presence and food availability. Studying a seabird that has evolved relatively low...

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...

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...

Caspian tern (Hydroprogne caspia) foraging ecology and predation on juvenile salmonids in San Francisco Bay, California

Creator:: Adrean, Lindsay J.
Abstract:: Brooks Island, located in central San Francisco Bay, California, currently supports the largest breeding colony of Caspian terns (Hydroprogne caspia) in the Bay Area, and is one of several proposed relocation sites for some Caspian terns from the world's largest colony in the Columbia River estuary of Oregon. Juvenile salmonids...
