AMERICAN CROWS American Crow (Corvus brachyrhynchos) Prevention and Control of Wildlife Damage 1994

Scientific Name: Corvus brachyrhynchos

Overview of Damage Prevention and Control Methods

Exclusion

Netting to exclude crows from high-value crops or small areas.

Protect ripening corn in gardens by covering each ear with a paper cup or sack after the silk has turned brown.

Widely-spaced lines or wires placed around sites needing protection may have some efficacy in repelling crows, but further study is needed.

Cultural Methods

Alternate or decoy foods; example: scatter whole corn, preferably softened by water, through a field to protect newly planted corn seedlings.

Frightening

Use with roosts, crops, and some other situations. Frightening devices include recorded distress or alarm calls, pyrotechnics, various sound-producing devices, chemical frightening agents (AvitrolĀ®), lights, bright objects, high-pressure water spray, and, where appropriate, shotguns.

Repellents

None are registered.

Toxicants

None are registered

Trapping

Check laws before trapping. Australian crow decoy traps may be useful near a high-value crop or other areas where a resident population is causing damage. Proper care of traps and decoy birds is necessary.

Capture single crows uninjured in size No. 0 or No. 1 steel traps that have the jaws wrapped with cloth or rubber.

Shooting and Hunting

Helpful as a dispersal or frightening technique but generally not effective in reducing overall crow numbers. Crows may be hunted during open seasons. Check with your state wildlife agency for local restriction.
