As recently reported in The Huffington Post Green, crows have been attacking Seattle-area police in the parking lot of an Everett Police Department precinct station.
The aggressive black birds have been swooping down and dive-bombing officers on their way to and from their cars. One officer who was attacked by a crow, noted that the birds were behaving like velociraptors. In an effort to scatter the crows, officers turned on their sirens to frighten them. Not only did this strategy of bird control fail, the crows “decorated” police cars with droppings.A wildlife department biologist noted that the crows are merely protecting baby crows that were ejected out of their nests and learning to fly. It’s a known fact among bird experts that crows are highly intelligent, so much so that the birds can actually recognize the individual features of people. Crows have also been known to hold grudges. So it stands to reason that if these crows perceive police officers as threatening to their young, they will attack them—or anyone else wearing a similar uniform.Clearly, what the Everett Police Department precinct station needs to do is implement an effective bird control strategy. Fortunately, there are a number of effective and humane bird control deterrents currently on the market. Here’s what the pros recommend:Stainless Steel Bird SpikesLarge birds like crows simply can’t get their wings around Stainless Steel Bird Spikes. The spiked strips are easy to install and can be glued down, nailed or screwed onto most any surface. They come in a variety of widths --1”, 3”, 5” and 8” --to match the area you want protect. The best stainless steel bird spikes are made in the USA and will have their spikes securely embedded in UV-resistant unbreakable polycarbonate. Approved by the US Humane Society and PICAS, the spikes are blunted at the tips and won't injure crows or installation crews.Bird Chase Super SonicEasy to place on precint buildings, garages, and similar open areas, the Bird Chase Super Sonic exploits a crow’s alertness to sound threats. The device continually broadcasts pre-recorded bird distress and predator calls. These sounds resemble natural bird sounds, so humans won't be bothered by them. Because of the socail nature of crows, they will hear the distress and predator calls and send the message along that there is a threat, and the birds will flee the area. The quality-constructed device is weather resistant and designed for outdoor use. It's easily programmed for day or night operation. Bird Jolt Flat TrackA low-profile, electrical bird deterrent track system, Bird Jolt Flat Track imparts a mile electric shock to the feet of crows (or any bird for that matter). Birds are quickly “instructed” to avoid the surface and will move on. The shock produced is harmless to crows, yet it creates an inhospitable area to the birds. Flat Track is made in the USA and comes in six colors to match the surface onto which it is installed. The track can be easily glued down to most surfaces.Crows are not dummies. They live in close communities and work together to defend their territories. Working in teams, they’ll use “spotters” as lookouts to warn the flock of impending danger. These birds are omnivorous scavengers that will devour virtually anything, including discarded food in and around garbage cans. Without effective bird control, they’ll hop on patio table and feast on your outdoor BBQ dinner.
If no food is immediately accessible, crows have been known to tear up lawns looking for grubs. If you have this problem, treat your lawn for grubs to keep the crows from doing any more damage. Removing the source of food is one way to discourage crows, but the sure fire way to get rid of crows is to use the bird control devices today's professionals use. Here are three suggestions:
Crows Dislike Spikes
by Alex A. KecskesIf you’re fortunate enough to live in a waterfront home, you’ve no doubt had to deal with gulls, cormorants or pelicans on your property. Without effective bird control measures to deter them, these birds can create a number of costly problems. Not the least of which is the build-up of bird droppings everywhere. Gull droppings on your roof, for example, are so acidic they can permanently damage roofing tiles. Cormorants like to build nests in lofty places, like chimneys, which can be dangerous to both bird and resident. Sometimes, gulls will bring muscles on your deck or rooftop and break them apart before eating. This can create a smelly mess, damage your roof and mar your deck.Seaside pest birds can wreak havoc with your outdoor furniture. Canvas awnings and umbrellas can become so covered with droppings that they will degrade the material to the point of tearing. Droppings on the sides of your home, deck or boathouse can require expensive removal and re-painting. So what can you do to protect your home from pest birds? Install some effective, humane bird deterrents. Here are few of the most popular for seaside homes:Marine Grade Bird SpikesThese won’t allow birds to land or perch. The best bird spikes are made of flexible, marine-grade stainless steel and feature a U.V.-protected polycarbonate base. The spikes are easy to install on rooftops, decks, light posts or other lofty areas birds often choose to land. The spikes come in 3-, 5- and 8-inch widths to cover areas up to 8 inches wide. For larger birds—like cormorants—you’ll need the Mega Spike, which protects landing areas with 7-inch long spikes. To keep pest birds out of your rain gutters, Gutter Spikes feature adjustable clamps at the base. Bird spikes are blunted at the tips and are approved safe by the U.S. Humane Society and PICAS (Pigeon Control Advisory Service).Visual Bird DeterrentsOften called Bird Scare Deterrents, these include Flash Tape and Reflective Banners than can be easily hung on decks, patio covers, and landing areas. They “spook” birds by crackling in the breeze and reflecting sunlight. Working on the same principle are Scare Eye Diverters, which sway and bob in the breeze. These teardrop shaped plastic panels feature large predator eyes to frighten birds. Finally, there are the Bird Scare Balloons, which also feature large predator eyes to keep pest birds thinking twice about landing. These visual bird deterrents can be effective, but you must move them around from time to time to convince birds they are a real threat. Sonic Bird ControlThese devices emit bird distress and predator calls that resemble normal bird sounds to humans. They make birds far too uncomfortable to stay. One popular sonic bird control unit can emit distress and predator calls for 22 different species of birds. Its built-in speaker covers up to one acre. The unit can be programmed to turn on or off at night, and you can even adjust the volume.
by Alex A. KecskesIt's no surprise that pest birds have become a nagging nuisance. The bird droppings, the nests, the noise---it's enough to drive you crazy. Add to that the maintenance and cleanup costs and you have a crying need for some serious pest bird deterrents. What homeowners, boat owners, facilities managers and municipalities have discovered is that they can fight back. And they don't have to use dangerous, harmful or ineffective methods to rid themselves of pest birds.Today's professional bird control experts have come up with a number of highly effective bird pest deterrents that can be used against a wide range of bird pests. Some are high tech and some are low tech. We'll start with the most simple devices.Consisting of reflective foils, tape banners and balloons, Bird Scare deterrents create an “Optical Distraction Zone” that birds would rather not go near. Some banners and tape produce a crinkling noise in the breeze that alarms pest birds. Balloons have the added threat of large predator eyes imprinted on them, which adds to the scare factor. These devices work to discourage a wide range of birds. They are easily installed and need only be refreshed from time to time so birds won't get bored.One manufacturer has developed the king of bird scare devices. Called the Scarecrow, this pest bird deterrent employs a motion-activated sprinkler to blast a burst of water whenever it senses an approaching bird. Ideal for gardens, backyards, pools/spas and other outdoor areas, the ingenious device combines water spray, the caricature of a moving bird's head and a sudden sprinkler sound to scare pest birds.Next up is the king of bird pest deterrents--the Bird Spike. No matter how smart or skilled, no bird alive can negotiate a landing around these threatening looking spikes. The blunted spikes attach to most any flat surface and are harmless to birds and people. Some manufacturers offer spikes in various colors and, when installed correctly, are unnoticeable from anyone looking up from the ground. The spikes are available in durable stainless steel or stiff, unbreakable polycarbonate. As a bird pest deterrent, spikes can't be beat. Some manufacturers offer a number of different types and sizes of bird spikes, each designed to deter a specific set of bird species and pest bird nuisance. For example, there's the Mega Spike, which has spikes that are typically 7” high to ward off large pest birds, such as seagulls, cormorants, turkey vultures and raptors. The best mega spikes are made of marine grade stainless steel for lasting durability. When evaluating this deterrent, opt for spikes that are crush proof with a non-reflective metal finish. And if you can, go with a U.V.-protected polycarbonate base that allows you to angle the spike to fit curved surfaces. If you're looking for a pest bird deterrent that keeps birds out of rain gutters, there's the Gutter Spike. These are ideal for large pest birds like seagulls, crows, and pigeons. The best gutter spikes feature adjustable clamps at the base to allow you to attach them to the lip of a gutter.Birds hate spindly arms that threaten to grab them. That's the theory behind the Bird Spider. This bird pest deterrent is ideal for keeping pest birds away from outdoor eateries. awnings, canvas covers, patios and other flat areas. To whisk away birds of different sizes, spiders come with varying arm lengths.A simple truth about all birds is that if they can't land, they won't stay. Our next pest bird deterrent exploits this truth. Unobtrusive to a fault, there's nothing threatening about the Bird Slope, yet no matter how many times they try and how skilled the bird, they just can't get a solid footing on these angled PVC panels. Ideal for eaves, ledges, beams and other similar niches, bird slopes are easy to install on almost any surface.Birds won't even try to land anywhere near our next bird pest deterrent--Bird Foggers and Misters. Once birds fly through the irritating mist dispensed by these systems, they can't wait to get the heck out of the area. The chemical--food-grade methyl anthranilate--is essentially a grape extract that's harmless to birds and humans. The more sophisticated fog/mist systems are equipped with timers and multiple nozzles that let you direct the mist to very specific sites in varying spray times and durations. Our next bird pest deterrent presents birds with an icky, sticky landing zone. And birds hate that. Called Bird Gel, the stuff has proven its worth on a wide range of pest birds. It goes on any surface, is practically invisible and stays sticky for a full six months. Gels are an ideal deterrent and will keep all manner of pest birds off ledges, conduit, pipes, I-beams and parapet walls. Sometimes only a physical bird barrier will keep pest birds from your property. And there's no better barrier than Bird Netting. Effective and humane, this bird pest deterrent has been widely used to keep birds out of groves, vineyards, enclosed courtyards and patios. You can get various net mesh sizes to deter any number of pest birds--from pigeons and sparrows to starlings and seagulls. You can also get bird netting that is flame resistant, U.V. stabilized, and rot- and water-proof. If you're going to put up netting for the long haul, these superior attributes are recommended.
Ultra Net comes in various bulk sizes and three different mesh openings--3/4-, 1/2- and 1/4-inch--to deter, pigeons, swallows, crows, gulls and sparrows. For smaller birds, use the 1/2- and 1/4-inch netting.
When bird proofing fruit trees, vegetable gardens, blueberry bushes and grape vines, suspend the netting above these plants. For trees, measure the circumference of the tree and cut at least one extra foot. Secure the netting with twine, zip ties, or hog rings.For blueberry bushes and grape vines, suspend the netting over the bush or vine and leave at least 6 inches of clearance. This keeps birds a safe distance away from your fruit when they land on the netting. Another way to install netting is to suspend it using poles positioned around the bush or vine.To bird proof vegetable gardens, wrap each plant in netting or suspend the netting around the entire garden area to create a bird barrier. To keep pest birds away from eaves and open spaces, install netting using clips or staples.Before installing any bird deterrents, the surface should be clean and dry. Thoroughly remove bird droppings, feathers and nesting materials. Birds are attracted to this debris and will consider the area “friendly.” Use commercial disinfecting cleaning agents to prevent exposure to any of the 60 known airborne diseases caused by birds. Use eye and respiratory protection if the area is heavily contaminated with droppings.For additional advice on how to properly install bird deterrents, consult an expert like the folks at Bird-B-Gone.
Bird Deterrents for Commercial Applications
Bird Spikes are an ideal way to keep larger birds such as pigeons and gulls from landing on commercial buildings. They are easily installed using adhesive, screws or tie downs. Use birds spikes to keep birds from landing on ledges, roof edges and peaks, parapet walls, windowsills and other flat surfaces. Be sure to cover the entire surface with bird spikes so the birds cannot land around them. Often times, if birds can land around the spikes, they will use them as a nesting area. Made from stainless steel or polycarbonate plastic, bird spikes are rugged and long lasting. Once installed there is little maintenance; periodic cleaning of debris buildup from nearby trees or shrubs is all it takes.Electric Bird Repellers are electrified track that give pigeons a small “jolt” when they touch the track. They are easily installed on parapet walls, roof edges and peaks, ledges and even channel letters. Install the track with an outdoor adhesive and connect to a solar or direct charger. When the pigeons are “Zapped” by the electrical current running through the track, they will change their landing and roosting habits and find another more comfortable area. Electric bird repellents are low profile, usually no more than ¼” high, which does not take away from the buildings aesthetics. These bird control tracks are one of the most specified systems by architects, government offices and contractors.Bird Netting is used on and in commercial buildings with severe bird problems. Bird net is an exclusionary bird deterrent; it excludes birds from areas that they are unwanted. Bird netting is ideal to use in large warehouses, airplane hangars, “Big Box” stores and food processing plants. It can also be used on building facades to protect signs, channel letters and architectural features. It is best to hire a professional to install bird netting, if not done properly, the netting may sag and allow birds to get underneath it.
