Double-crested cormorants (Phalacrocorax auritus) have been identified as the source of significant mortality to juvenile salmonids (Oncorhynchus spp.) in the Columbia River Basin. Management plans for reducing the size of a large colony on East Sand Island (OR, USA) in the Columbia River estuary are currently being developed. We evaluated habitat enhancement and social attraction as nondestructive techniques for managing cormorant nesting colonies during 2004–2007. We tested these techniques…

Living with Double-Crested Cormorants (Phalacrocorax auritus): A Spatial Approach for Non-Lethal Management in Toronto, Canada
Abstract. Tree mortality incurred through the nesting habits of Double-crested Cormorants (Phalacrocorax auritus) can cause human-wildlife conflicts, often resulting in the lethal control of
A Low-Disturbance Capture Technique for Ground-Nesting Double-Crested Cormorants (Phalacrocorax auritus)
A tunnel-based technique for capturing specific adult Double-crested Cormorants at a ground-nesting colony was developed to reduce risks of nest failure and colony abandonment, and would be particularly beneficial for other wary and easily disturbed species.
Nesting of Great Cormorants (Phalacrocorax carbo) on man-made structures in Ukraine
In Ukraine the G reat C ormorant ( Phalacrocorax carbo Linnaeus, 1758) uses a rather wide range of habitats for nesting : islands, trees and shrubs, reedbeds and a variety of man-made structures. In


Colony Connectivity of Pacific CoastDouble-Crested Cormorants Based onPost-Breeding Dispersal From theRegion’s Largest Colony
Results of this study indicate that some cormorants from ESI could disperse to prospect for nesting sites throughout much of the western portion of the range of the Western Population; however, regional variation in connectivity with the ESI population, distance from E SI, and site-specific nesting history will likely result in variable prospecting rates among regions and sub-regions.
Environmental contaminants, human disturbance and nesting of double-crested cormorants in northwestern Washington
-Double-crested Cormorants (Phalacrocorax auritus) in extreme northwestern Washington produced few young (0.27/occupied nest) in 1984; the clutch size was generally small and eggs, if laid at all,
Foraging patterns of male and female Double-crested Cormorants nesting in the Columbia River estuary
It was determined that nesting adults tended to forage >5 km from the colony and foraging distribution was distinctly different between the sexes, and gender differences in foraging patterns may allow this large and growing colony to remain productive while potentially competing for food with many thousands of other piscivorous waterbirds that use East Sand Island.
Recent Population Size, Trends, and Limiting Factors for the Double-Crested Cormorant in Western North America
The status of the double-crested cormorant (Phalacrocorax auritus) in western North America was last evaluated during 1987-2003. In the interim, concern has grown over the potential impact of
Changes in the Status, Distribution, and Management of Double-Crested Cormorants in Wisconsin
We reviewed and summarized historical data and conducted population surveys from 1973 through 1997 to determine the breeding status and distribution of doublecrested cormorants (Phalacrocorax
Effects of colony relocation on diet and productivity of Caspian terns
Results indicate that relocating the Caspian tern colony was an effective management action for reducing predation on juvenile salmonids without harm to the population of breeding terns, at least in the short term.
Foraging Location and Site Fidelity of the Double-crested Cormorant on Oneida Lake, New York
Abstract We studied the foraging behavior of the Double-crested Cormorant (Phalacrocorax auritus) on Oneida Lake, New York, by monitoring the activities of 27 radio-tagged birds in July and August of
Historic Populations of the Double-crested Cormorant (Phalacrocorax auritus): Implications for Conservation and Management in the 21st Century
Comparison of historic and current records challenges the opinion that cormorants are currently overabundant, and suggests that perception of overABundance rests on socio-political rather than biological or ecological factors.
Spatial and temporal variation in the diet of double-crested cormorants (Phalacrocorax auritus) breeding on the lower Great Lakes in the early 1990s
The results indicate that temporal and spatial variation, as well as the technique for diet determination, are very important factors that must be considered when assessing the effects of double-crested cormorant predation on fisheries.
