How to Keep Ravens Away from Buildings, Garages, Houses, Farms, and More

Got a Raven Problem?

Ravens are a problem for all types of properties, from parking lots to agricultural fields, to suburban homes and even buildings in urban areas. Flocks of ravens create a lot of noise, leave messy droppings that can spread disease, strew garbage around, and cause property damageĀ to buildings and landscaping. Ravens are also major agricultural pests that damage crops, particularly corn, peanuts, sunflowers, pecans, and various fruits. In some instances they prey on livestock, such as newborn lambs or goats.

Scaring Ravens Away: Audio and Visual Deterrents

Visual and audio deterrents are a form of harassment techniques designed make scare ravens and make them uncomfortable enough to migrate to another area. Ravens are much more likely to vacate a new roost site rather than an established one so it is important to act quickly after they arrive.

It is possible to drive away large flocks of ravens and other blackbirds with audio and visual scare devices such as the Bird Gard unit combined with visual scare devices like Scare Eye Balloons, Octopus, and Flash Tape reflective tape.

To maximize effectiveness, hang visual products in trees before commencing a noise campaign.

Bird Netting to Keep Ravens Away from Buildings and Gardens

For small gardens and orchards, four-inch or smaller flexible mesh bird netting will keep ravens out. For other structures and buildings, ourĀ StealthNetĀ® Bird NettingĀ can be used to deter ravens from any enclosed or semi-enclosed area. StealthNet Bird Netting is available in three mesh sizes, all of which will deter ravens: 3/4,” 1-1/8″, and 2″.

What About Killing or Trapping Ravens?

Local laws that regulate the hunting, killing, or trapping of ravens vary from state to state. Nationally, ravens are protected under theĀ Migratory Bird Treaty Act, which is enforced by the U.S. Fish and Wildlife Service. However, under federal regulations, ravens can be killed without a hunting license or permit when caught threatening or damaging trees, agricultural crops, livestock, or wildlife.

Lethal means of control can also be taken legally when ravens are concentrated in roosts so large that they constitute a nuisance or pose a health and sanitation hazard. However, it should be noted that shooting is not generally considered to be an effective way to manage raven populations. Also, if you are considering lethal means, keep in mind that ravens are social birds and the flock is in constant communication, which can make hunting and trapping very difficult.

Effective bird deterrents and repellents are not only much more humane, they are also usually the best solution, without negative environmental effects, dead birds to clean up, or public relations problems.


Raven Identification and Behavior

Getting to know more about ravens can help you better understand and effectively solve your raven problem.

Identifying Ravens

There are three main species of crows found in the United States, the large American crow, found all across North America, the smaller Fish crow found in the Southeast, and Northwestern crow, which is generally only found on the Pacific Coast from northwestern Washington up through southern Alaska.

The American (or Common) crow is coal black from bill to the tip of the wing and claws with a metallic violet gloss on body and a blue-violet or green-blue gloss on wings. Adults have black eyes while juveniles have blue eyes. It grows to approximately 17 to 20 inches long with a strong, stout build and a compressed bill.

The Fishing crow and Northwestern crow are smaller, darker versions of the American crow. It is incredibly difficult to tell species of crow apart visually.

Info on Habitat, Diet, Nesting, and Breeding Patterns

Habitat

Ravens thrive in a wide variety of habitats though they prefer to be near farms, fields, and grassland for foraging, and woodlands and forest edges for roosting and breeding. They have adapted quickly to suburban and urban environments, roosting in city parks as well as on billboards, power lines, telephone poles and other man-made structures.

Diets

All ravens are omnivores. They will eat pretty much anything they can find, including garbage, carrion, insects, seeds, grain, berries, fruit, spiders, snails, earthworms, frogs, small snakes, mice, shellfish, and even the eggs and young of other bird species. Theyā€™ve even been known, in rare cases, to hunt the young of other species, such as newborn lambs or goats.

Ravens are opportunistic and always on the lookout for new food sources. They will scavenge, steal, and hunt anywhere they find food. They feed mostly on the ground, which is why you might see unsecured trash scattered around on a property near raven roosting spots. Though they do provide some beneficial insect hunting on farms, ravens often cause agricultural damage by eating newly planted seed or vulnerable early crops, especially corn. They can also cause significant damage to tender fruits and vegetables.

Nesting

Ravens are committed nest builders. Ravens typically build nest sites in the forks of tree branches or large shrubs between ten and seventy feet above ground. They rarely build nests on building ledges. Raven nests look like large baskets made of sticks, twigs, and mud with shredded bark, grass, feathers, or other soft material as liner.

Breeding Patterns

Ravens have one or two broods a year, averaging four to seven eggs per brood. Incubation takes eighteen days with a four- to five-week fledgling period before the young leave the nest. The eggs range from pale bluish-green to olive green or greenish-brown with splotches of brown and olive-gray.

Migratory Patterns

Northern ravens will fly thousands of miles south during the winter, while southern birds stay put year round.

Flocking Behavior

One notable characteristic about ravens is their flocking behavior. In fall and winter, they will move to better feeding areas where they will coalesce into massive feeding flocks. These feeding flocks in turn, join up with other flocks at night to form enormous communal roosts numbering from a couple thousand to tens of thousands.
