Bird Strike Testing

Bird strike testing is an important aspect of aviation these days. Bird strike is an aviation term for when there is a collision between a bird and an aircraft. It is a common threat to aircraft safety and has caused a number of fatal accidents. One of the safety concerns plaguing the aircraft industry since its inception has been bird strikes, or bird ingestion. Flocks of birds seem harmless enough when admiring them from the ground, but experiencing them from the cockpit of an aircraft can prove lethal. A 12 lb Canadian goose struck by an aircraft traveling 150mph at liftoff generates an impact force similar to that created by a 1000lb weight dropping from a height of 10ft. More than 300 people have been killed by bird strikes since the first fatality was recorded in 1912. Since 1960, aircraft-bird collisions destroyed 20 U.S. registered commercial aircraft and, since 1985, 23 U.S. military aircraft. The most common impact areas on the aircraft include the engine inlet, the nose, the canopy, and the wing U.S. Air Force (USAF) officials have reported more than 2500 strikes annually, not including strikes to commercial and U.S. civil aircraft. This became the main reason for carrying out bird strike testing on planes.

At present, all aircraft are required to pass a certification test to ensure safe aircraft flight and operation in the event of a bird strike testing. The current certification test for bird strike testing is performed by firing birds from gas cannon onto aircraft components such as windshields, windows, aircraft engines and leading edge structures. During the design and development stage of new aircraft, an artificial bird is often used in place of the real bird; this helps to improve the repeatability of the bird strike testing and reduce the biological hazard associated with the real birds.

Artificial birds used in bird strike testing are often manufactured from gelatine and formed into a simple primitive geometry (cylinder, hemispherical ended cylinder etc.) to represent the principal mass of the bird (torso). Although previous work has shown good agreement between artificial and real birds (impact pressure and impulse), there are certain situations where this is not the case.

In recent work, the influence of bird shape for large bird species such as the Canada Goose has been investigated using computer stimulation. To control the problem airports invest in bird strike testing management and control, changes to terrain around the airport to reduce its attractiveness as habitat to birds, using bird control personnel and frightening devices (sounds, lights or polytechnics) and sometimes the use of falcons or similar. Pilots use awareness of bird habits and should avoid migratory routes and they will not only ensure safety, this may even ease the load for bird strike testing.

Bird Roadrunner

The bird roadrunner is the state bird of New Mexico. It was officially adopted on March 16, 1949. It was adopted under the name “Chaparral bird”. In Spanish, it is called “El Correcaminos”. The comical roadrunner prefers running to flying and has been clocked at speeds of 15 miles per hour. They are approximately 22 inches in length and their diet consists of insects, lizards, centipedes, mice and snakes. Bird roadrunners are quick enough to catch and eat rattlesnakes.

The two species of bird Roadrunners include the Lesser Roadrunner (G. velox) a slightly smaller, buffier and less streaky bird, of Mexico and Central America, which grows to a length of 18 inches. The Roadrunner is a large, black-and-white, mottled ground bird with a distinctive head crest. It has strong feet, a long, white- tipped tail and an oversized bill. It ranges in length from 20 to 24 inches from the tip of its tail to the end of its beak. It is a member of Cuckoo Family (Cuculidae), characterized by feet with 2 forward toes and 2 behind.

The Roadrunner inhabits open, flat or rolling terrain with scattered cover of dry brush, chaparral or other desert scrub. The bird roadrunner feeds almost exclusively on other animals, including insects, scorpions, lizards, snakes, rodents and other birds. Upto 10% of its winter diet may consist of plant material due to scarcity of desert animals at that time of the year.

During spring time, the male bird roadrunner in addition to acquiring food for him, offers choice morsels to a female as an inducement to mating. He usually dances around her while she begs for food, and then gives her the morsel after breeding briefly.

Both parents collect the small sticks used for building a shallow, saucer-like nest, but the female actually constructs it in a bush, cactus or small tree. Female bird roadrunner then lays from 2 to 12 white eggs over a period of 3 days, which results in staggered hatching. Incubation is from 18-20 days and is done by either parent, though preferably the male, because the nocturnally incubating males maintain normal body temperature. The species of roadrunner prefers arid deserts and other regions with a mix of scattered brush for cover and open grassy areas for foraging. For breeding, bird roadrunners require coastal sage scrub or chaparral habitat. In the outer limits of their range they may be found in grasslands and at the edges of woodlands.

Bird Rid

Bird Problems have become a major issue off late and problems caused due to birds are being taken very seriously. Some of the major outbreaks of diseases in the recent times have been caused by birds. Be it the avian bird flue or other bird caused ailments, their effect is wide spread as birds are highly mobile in their general life pattern. Bird Rid thus is an area that assumes critical importance in the quest to reduce problems caused by birds.

Studies have proven the fact that bird disease outbreaks tend to spread much more quickly as compared to other occurrences. The reason for this is the fact that birds are often domesticated and otherwise are considered harmless and their access to human establishments is virtually unrestricted. Bird Rid is thus an area of extreme caution as it poses various kinds of threats.

Bird Rid is now a fully scientifically developed technique. Gone are those days when normal scare crows were the only ways for us to implement non lethal Bird Rid. Now various non lethal scientific technologies have been developed that make the use of ultrasound waves and other more developed visual aids to get rids of birds. Sonic Bird Rid devices are perhaps the most recent and advanced in this realm of Bird Rid. These devices were basically developed to cater to the area of airports where bird hits to airplanes have been causing a serious hazard. Various Sonic Bird Rid devices have been developed. These devices basically used high pitched sonic waves to scare the birds away. Ultrasonic waves emanated by high tech electronic circuitry keep the bird flocks away from the area. Coupled with very low electric consumption, his device has proved to be one of the most efficient and effective means of Bird Rid. Various other variations of sonic devices are available in the market these days and each has different advantages and efficiencies.

Other traditional methods have been developed and have been more effective. Scare crows have been replaced by 3 D visual devices called as terror eyes that seem to follow the bird flocks and scare them away. Bird Rid has been implemented using various types of technologies but still prevention is better than cure and the onus is on us to avoid the creations of circumstances that help breed birds in the region. This is the single most effective way of implementing Bird Rid and has proved to be successful in the long run.

Bird Problems Residential

Bird problems residential is a serious problem which we are facing today lets have a deeper introspective into it. Birds are among the most frustrating and pesky pests that a person may encounter. They are cute and loved by most people who see them, but they can create a plethora of problems. Birds seem to be harmless intruders, but they can be a dangerous public health threat and can create other problems. The general public's affection toward birds translates into a serious underestimation of the health risks associated with pest birds. Especially in residential areas, where little children, while playing in open grounds come in contact with the faeces of birds which causes them to suffer from an assortment of diseases. Also, in many residential colonies birds have attacked many people, at times leaving them blind. It’s under such circumstances when once realises that birds too have an innate Mr. Hyde in them and we realise the bird problems residential.

Serious consequences and problems may be arising when birds roost on a ledge of a window, when woodpeckers peck on the sides of a house, when starlings destroy plants or crops. Flocks of ducks and geese have been known to chew and destroy turf and grass. Flocks of birds congregating on electric wires or trees make an absolute and unhygienic mess with their droppings. Those birds that have found a home in local residential areas put immense stress on local plants and food supplies. These are just a few of the bird problems residential.

Leaving aside residential areas, we hear so much of the bird menace as modern aviation’s nightmare which is another consequence of bird problems residential. The collision of airplanes with birds has been a big problem; it only arose as a result of man’s short-sightedness in dealing with nature. This is a more delicate problem, which needs to be tackled. It will be inhumane to kill the birds, which happen to come in the way of an aircraft, however, killing birds by shooting has been and is a practice, at civil and military aerodromes the world over. As usual man is caught between a torment sea and a cliff, because there have been lots of cases in residential areas where not just children but also adults have suffered serious infections and diseases caused due to the droppings of birds, then again just for our survival how can we kill a fellow member of the animal kingdom? So I think we had an immense insight into the bird problems residential.

Bird Egg Identification

3-d oval shaped may or may not be white, with or without spots, varying in their external appearance - there are so many types of eggs. Here, we talk of only birds’ eggs. All birds lay eggs. These exhibit a great diversity of shape, colour and patterns. Despite their fragility, the calcium carbonate shells provide protection and a self-enclosed environment for the developing chicks. Bird egg identification is complicated because there are so many species of birds and they lay eggs that are externally different. It has taken scientists years to learn the art of and formulising methods on how to recognise and identify the eggs of different birds. It is quite an art, and because it is done through scientific means it’s a scientific art. Therefore, bird egg identification is by all means a scientific art.

Most eggs that are laid in sheltered nests or holes in the ground are white and those laid in uncovered nests have protective colouring. Birds’ eggs differ greatly in size making bird egg identification quite scientific. Hummingbirds lay the smallest eggs and ostriches the largest, making identification of these birds’ eggs easier. The eggs of most birds are shaped like domestic chicken eggs. However, the eggs of cliff-nesting species are sharply pointed at one end. The shape of these eggs prevents them from rolling off the cliff. Many birds have plain-coloured eggs. The eggs of ground nesters are heavily camouflaged with speckles and other markings. Birds' eggs are unique in their diverse pigmentation.

This diversity is greatest amongst perching birds, also called passerines, which make up almost 60% of all bird species. This category includes many familiar species including tits and warblers. Most passerines lay eggs speckled with reddish protoporphyrin spots forming a ring around the egg's blunt end, on an otherwise un-pigmented shell. Scientists and ecologists suggest that rather than giving a visual signal, protoporphyrins strengthen the eggshell by compensating for reduced eggshell-thickness caused by calcium deficiency. Pigment spots on great tit eggs specifically marked thinner areas of shell, with darker spots marking yet thinner shell than paler spots, and females nesting on low-calcium soils, laid thinner-shelled, more-spotted eggs than those on high-calcium soils nearby. Pigmentation may offer a way to assess eggshell quality and aids in bird egg identification.

Bird egg identification of South American game birds is the most intriguing because they have solid metallic colors and a finish like that of a new automobile. Most birds that nest in dark holes, like the kingfisher and the woodpeckers, lay plain white eggs; whereas those of the kill deer and terns laid in exposed places with no protecting nest are colored like the soil or gravel and are very difficult to find. The majority of birds that build protective nests lay eggs having a ground color of some delicate tint with spots, streaks or scrawls of darker pigment such as purple, brown or black and, often, this forms a kind of wreathe around the larger end. Robins and bluebirds have blue eggs but those of some other thrushes are spotted with darker color. These formulae and methods formulated by scientists have made the whole process of bird egg identification, so much simpler.

Bird Dropping Removal

Bird dropping removal is an unpleasant problem being faced. One thing is always transformed into the other; whatever goes into a machine is reproduced again in another form. These are all basic laws of the nature. The little beautiful creature, bird also goes through the various biological processes. The bird’s body system is also like a machine that digests the food eaten up by it, extracts the energy from it and then removes the waste. And there arises the issue of bird dropping removal.

This bird waste causes a lot of problems for us. The birds wander around freely dropping their waste anywhere. Thus bird dropping removal is an unpleasant sight. We all love clean environment but birds dropping removal cause a lot of mischievous. The birds drop down this waste anywhere; we can see them all around the parks, benches, roofs, vacant plots. Every place is good for them but this causes problem for we people. Imagine that you go to a beautiful park to enjoy the beauty, sit on the roof for breathing fresh air and you get tired .So what would you look for, Ofcourse a place to relax. But if you find only a single bench and that too with the bird's waste on it, then what would be your reactions; of-course you would like to shoot that bird which created all this.

But since we cannot restrict to the freedom of the bird, we have to cope up with all this. If we have to enjoy them flying around in clutters or wish to be awakened up by the sweet song of the bird on our balcony then we have to tolerate this entire nuisance created by them. The bird dropping removal cannot be stopped from carrying on this activity but the only solution is cleanliness.

So if we want to cope up with this problem of bird dropping removal we have to adopt cleaning measures. Frequent cleaning of parks, benches, and roofs can be the only solution. Besides this cleaning measure has to be frequent and early as dried waste become difficult to be removed. Also the irritating sight and the smell spoil the environment. There are also some cleaning agents found in market for the cleaning purpose. So for clean and green environment what we all can do is to clean rather than avoiding the bird dropping removal.

Bird Barrier Roof

What is Bird Barrier Roof? Let’s See. Bird caused problems are often not taken seriously unless one has personally been at the receiving end. Birds have a harmless image in the human mind and the independence of thought and life that they portray often supercedes the many problems that they cause. Apart from being carriers of certain serious diseases, birds most often cause troubles as encroachers in our constructions. Birds such as woodpeckers not only cause structural damages but also tend to roost in critical places such as business hoardings etc. Bird Barrier Roofs are an ideal solution to such problems and offer a simple yet highly effective solution to this problem.

Bird Barrier Roofs are a perfectly non lethal solution to this problem of bird encroachments and help us seal off access to a certain area of our construction. Different birds tend to be attracted to different constructional areas. For example sparrows generally nest and roost on beams where as pigeons often nest on elevated regions such as banners or signs. Therefore Bird Barrier Roofs are also specialized for a certain area and a certain bird type.

Bird Barrier Roofs are basically net like devices which are constructed in various shapes and with materials of various strengths depending upon the type of area to be protected. The strength of the material used generally depends upon the weight category of the target birds against which protection is sought. The great thing about Bird Barrier Roofs is that they are high stealth devices and are virtually invisible to the naked eye from a distance.

Various firms provide Bird Barrier Roofs. The great part about these devices is that their installation and maintenance is very easy. Although company engineers install the devices but installing the Bird Barrier Roofs is not a great task. Using simple fasteners and hooks these net like structures can be easily set up. Thus Bird Barrier Roofs have become a very popular aid to help against the problem of bird encroachments in our constructions. Not only are they cheap and easy to set up but they are highly effective and non lethal methods of preserving nature and human interest side by side.

The Baltimore Oriole Bird

Baltimore OrioleThe serene beauty of the alluvial shores of Mississippi is beyond words. One feels enchanted by the varied vegetation on its shores. But nothing like the feel of sweet melody sounding in one's ears. This aesthetic chant is of the Baltimore oriole Bird. These birds are 7 - 8 1/2 inches long. The male Baltimore oriole bird is black with orange under parts, rump, shoulders, and sides of tail. The wings have 2 white wing bars. The females are olive above, yellowish below with 2 white wing bars.

The Baltimore oriole bird arrives from the south, perhaps from Mexico, or perhaps from a more distant region, and enters Louisiana as soon as spring commences. It then searches amongst the surrounding trees for a suitable place in which to settle for the season. It prefers the trees that grow on the sides of a gentle slope. The male bird is more active as compared to his female counterpart. They weave their nest after finding a suitable place on the tree. This nest contains no warming substance, such as wool, cotton, or cloth, but is almost entirely composed of the Spanish moss, interwoven in such a manner that the air can easily pass through it. The female lays from four to six eggs at a time and the incubation period is around 14 days.

The movements of these birds are elegant and stable. Their song consists of three or four, loud, full, and mellow notes, extremely soothing to the ear. The main reason behind this is the pitch and frequency of their notes which are immensely pacifying to the human hearing system. Before the young Baltimore oriole bird is quite able to leave the nest, they often cling to the outside of the nest, and creep in and out of it. When they leave their home, they follow the parents for nearly a fortnight, and are fed by them. The Baltimore oriole bird is one of the many endangered species. Despite the special status given to it, the number of Baltimore Orioles has been declining. This loss is attributed to destruction of breeding habitat and tropical winter habitat. We should take serious measure to prevent extinction of this wonderful gift given by Mother Nature.

Arizona State Bird

The Arizona state bird is also popularly known as Cactus Wren. It was chosen as Arizona state bird by the Arizona Legislature in 1931. It is the largest wren in Arizona, measuring 7-8 inches in length. It remained Arizona's only official wildlife representative until 1985. Cactus Wren can be easily recognized from it’s rather raucous chirp which is much like the sound of a car engine trying to turn over.

The Cactus Wren's back is brown with white spots and its under parts, including the throat, are lighter colored with black spots. The bill is as long as its head and curves down slightly. The Arizona state bird’s wing feathers have white bars and its tail has black bars. A distinctive white line appears over each eye. It is generally found in the low lying areas and parts of Utah, Texas, New Mexico, California, and Mexico. They can also be seen in the desert habitats as well as open woodlands or grasslands

Arizona state bird is omnivorous (both plant and animal eating), scrounging for insects on the ground and in trees and shrubs and also feeding on seeds and fruits. They are active during daylight hours at any time of the year. Cactus Wren eggs and the young wrens are vulnerable to smaller predators such as Blue Jays and snakes; the adult birds are rarely preyed upon. The male bird is more active as compared to its female counterpart.

Arizona state bird also weaves their nests in a very special manner. Their nests are football-shaped, made of grass, and lined with feathers and quite large as well. Cactus Wrens usually build their nests in thorny trees to protect themselves and their young ones from predators. This kind of vegetation is generally found in the desert regions. These nests serve as a home for year-round protection from the cold, the rain, and predators.

The female Arizona state bird lays 3-4 eggs at a time and the incubation period is around 16 days. The young ones leave the nest in about 3-4 weeks. The lifespan of the Arizona State bird is rather short. It lives for around 2-4 years. The cactus wren is protected by federal law. It is illegal to hunt or possess live specimens. Because of its adaptability to the varying climate in this region, the future looks good for the “Arizona State Bird ".
