I. Different types of crows

Crows are large passerine birds that comprised the genus Corvus in the Corvidae family. These are the most common crows found in North America.

* The American crow (Corvus brachyrhynchos) is a large species of passerine bird in the Corvidae family. It is a common bird found throughout much of North America. In the interior of the continent south of the Arctic, it is simply called a raven, as no other such bird lives there on a regular basis.

* The fish crow (Corvus ossifragus) is a typical crow in appearance that is associated with wetland habitats. This species of bird is superficially similar to the American crow, but it is smaller (36-41 cm long) and has a silky soft plumage in comparison.

The differences are often only really apparent between the two species when they are side by side or by their calls. The beak is usually somewhat thinner than the American crow, but again, this may not be of much help when there is no other bird to compare.

* The common raven (Corvus corax), also known as the northern raven, is a large, all-black passerine bird in the raven family.

II. Crows like pests

Not only do crows feed on freshly thrown seeds in rural areas, but they also gather every night, starting with groups of half a dozen, which then join together to form a group of twenty to thirty and so on until the flock is quite big and noisy. They have a habit of going back to the same place every night.

Machinery of various kinds are often used to frighten crows, such as miniature windmills or horse bells that are set in motion by the wind; however, all of these devices soon become familiar to birds, so they quickly become useless.

III. Basic Raven Control

* The Scarecrow: The most effective method of banishing crows from a cornfield, in terms of experience, is to combine scarecrows with frequent use of the shotgun. Nothing terrifies these sagacious animals more than the sight of a game and the explosion of gunpowder, which they have known so many times to be fatal to their breed. But of course, if you want, you can put the gun down. The scarecrow is a device, traditionally a human figure dressed in old clothing or a mannequin that is used to deter crows from disturbing crops (hence the name).

Modern scarecrows rarely take human form. In California farmland, highly reflective aluminum PET film tapes are tied to plants to create reflections from the sun. Another approach is automatic noise guns that run on propane gas.

The scarecrow method is a motion sensor sprayer and is a great method of getting rid of crows. It is not possible for the raven to get hurt, and other creatures such as squirrels, raccoons, deer, dogs and cats are also repelled. It might also be fun to try out fireworks, strobes, sirens, horns, music, or right-hand talk radio.

Perch repellants: Crows are difficult birds to eliminate because they are persistent pests and their populations in urban areas are usually quite numerous. If you live in a rural area, crows control is pretty simple: scare them or shoot them. If you live in an urban area, the chance of being arrested after shooting a gun in the open air is high.

Your first line of urban defense against crows is mechanical perch repellent, those sharp wires and needles you see on the shelves and ceilings of many state institutions.

* Bird Repellants – There are a ton of bird repellent chemicals and devices on the market today. You can’t type bird control into a search engine without a full results page filled with home pages from bird control device manufacturers.

However, one of the most trusted brands in the bird repellent market is Bird-X. Bird-X’s policy is to provide non-lethal, non-harmful, environmentally safe and environmentally sound products, or so they say. Check it out to confirm these claims. Additionally, Bird-X regularly receives referrals from the Audubon Society and USDA’s Animal Harm Control division. You can’t go wrong with the endorsement of the Audubon Society.
