American crows ( Corvus brachyrhynchos ) have a long history of causing agricultural damage in North America. Shooting and bombing at crow night roosts have been employed to reduce such damage. Most roosts were located in rural locations, but in the latter half of the 1900s crows began to roost in urban locations. Urban crow roosts are presently a nationwide problem in the United States. Thousands of crows at a roost create problems for businesses and residents. Improved control techniques are… 

Non-Lethal Management to Reduce Conflicts with Winter Urban Crow Roosts in New York: 2002 - 2007

American crow populations have increased steadily since 1966 in many parts of the U.S. Large winter congrega- tions of crows in urban environments have resulted in an increased number of requests for

Effigies for Dispersing Urban Crow Roosts

It is concluded that crow effigies (carcasses, taxidermic mounts, or artificial models) are useful components of roost dispersal efforts and can possibly be used in other applications, such as crop damage management.

Are birds scared by rotating mirrors

Blackbirds (Icteridae) create human health and safety concerns when roosting in large numbers near airports or other urban areas. Therefore, there is considerable demand for effective nonlethal

Effectiveness of lasers to reduce goose grazing on agricultural grassland

In recent decades, wild goose populations have grown considerably. Geese forage extensively in agricultural fields leading to frequent conflicts with agricultural stakeholders and calls for effective

Effectiveness of a Motion-Activated Laser Hazing System for Repelling Captive Canada Geese

The motion-activated laser hazing system effectively repelled Canada geese in captivity.

Daily Change in Spatial Distribution of Jungle Crows in Urban Areas

Jungle crows (Corvus macrorhynchos) have increased in number in urban areas across Japan, creating various kinds of problems. In the present study, jungle crows were counted at 33 study plots located

Seeing Is Feeding for the Frugivorous Bird Brown-Eared Bulbul (Microscelis amaurotis)

The results show that visual blocking could be a promising new technique to prevent bird damage.

Corvids in Urban Environments: A Systematic Global Literature Review

A review of the global literature on the effects of urbanization on species of family Corvidae indicates that corvids show both flexibility in resource use and behavioral plasticity that enable them to exploit novel resources for nesting and feeding.



Characteristics of American Crow Urban Roosts in California

American crows (Corvus brachyrhynchos) roost in urban areas across the United States creating problems resulting from fecal droppings, noise, and health hazards, and a logistic regression model was developed with 4 variables that correctly classified status of 85% of roost or nonroost trees.

Lasers as nonlethal avian repellents

It is contended that lasers will prove useful as avian repellents, but further controlled studies are needed to evaluate species-specific responses relative to laser power, beam type, wavelength, light conditions, and captive versus field scenarios.

Midwinter Distribution of the American Crow in New York State

The American Crow (Corvus brachyrhynchos) because of its gregarious roosting habits lends itself admirably to census methods. In New York State the winter range of the crow falls conveniently into 20

Evaluation of moderate and low-powered lasers for dispersing double-crested cormorants from their night roosts

The double-crested cormorant (Phalacrocorax auritus) is the primary avian predator on the southern catfish industry, estimated to cause $5 million in damage per year. To date, the most effective

Urban crow roosts - a nationwide phenomenon?

We conducted surveys of federal officials nationwide and of local officials in California to determine historical and temporal aspects, location, size, and control of American crow (Corvus

The Midwinter Distribution of the Crow in California

A survey of wintering crows in California was conducted during the years 1935-40, patterned after the New York State survey of 1932-33, with the cooperation of game wardens, county agricultural agents, farm advisers, high school instructors in vocational agriculture and many independent individuals.


BIO-ACOUSTIcs has developed rapidly in the past decade as a tool in the study of communicative mechanisms in wild birds (Hinde, 1969). The Common Crow (Corvus brackyrhyncihos) is an ideal

Crow damage to almonds increasing; no foolproof solution in sight

Of all birds causing damage to almonds in Sutter and Yuba counties, crows cause the most, according to a survey of growers, and growers are willing to spend far less than the potential value of nuts lost.
