Feathered Cockroach
They are European starlings, Sturnus vulgaris L.
It was introduced at Central Park in New York in 1890 by the American Association for Adaptation (Foreign Immigrants), not only thriving, but also an estimated 200 million birds covering all of North America. Zarzur is an incredible example of adaptation and survival, the ability that has made it the nerve of bird watchers everywhere.
In the suburbs around the country, large groups of starlings can appear to empty feeders within a day or shrink to nothing in a few short hours making it impossible to attract local species.
The 100,000-acre swarms descended from farms and livestock plants throughout the United States. They eat fodder, feed contamination and water supply with their waste, and can transmit diseases such as the gastroenteritis virus through their feces. They consume cultivated grains, damage fruit crops such as grapes and cherries, and make the areas they frequented usually ugly.
This is not half of it.
They are the mafia thugs of the bird world. They are relentlessly exiting indigenous populations, destroying eggs or young people in this process. They can compete with Woodpecker, Purple Martins, Chickadees, Bewick's, House Wrens, or even out of competition, and even larger species like Flicker and Kestrel.
Woodpecks who dig new holes become victims, and secondary species that can not dig themselves, looking for holes in the abandoned woodpecker (west and the mountain of Bluebird, for example) also find themselves homeless.
According to the Audubon Society, most local species breed one incubator each year, whereas the starling sites at early spring locations are more than most, and are starting to produce two nurseries into three incubators. The number of indigenous people is growing and growing, and each year is getting worse. If you are a bird without a nest, you are a bird without a bosom, and if the worst comes to the worst, the species without a future.
If you live in the city, you've seen them. They feed anywhere, everywhere and look for anything good to eat: grassland provides invertebrates (worms and larvae), while parks and parking provide delicious foods like bread crumbs and bits of anything else that hits the ground. They are often mixed with birds and freckles which are characterized mainly by their white spots. In the summer, the purple and green feathers turns iridescent, the yellow beak bright; not so in autumn.
During hawthorn the winter is flocking and community famine by hundreds, even thousands. In the northern regions, they migrate short distances after food supplies, but here in Oregon, where the climate is relatively mild and the food seems plentiful and they stay. Bird scientists from the coast to the coast agree that the starch undoubtedly harms local species, but it is difficult to quantify them.
According to Tina Phillips, a biological scientist and project manager for the Cornell Bird Science Laboratory at Bird House, no one could prove that the starch was solely responsible for the decline of native species.
Starling and English birds both prefer urban areas, especially newly developed agricultural land. They go where we go. That's why the Oregon wilderness is free of starlings.
Tina told me that our cities in the 1950s and 1960s were affecting the enormous gains of the population. During that same period of time, Bluebird's numbers fell alarmingly. With focused surveillance programs across the country, such as the Cornell's Birdhouse Network, have been recovered to some extent, but there is much to be done.
According to statistics published by the North Berry Berry Network and Grape Network (University of Oregon, University of Idaho and Washington State University) among the pests that destroy the berries, the birds are the most problematic. 10% of the berry crop is lost to birds (including native species such as Ruben and Rennes), but losses range to 60%.
Throughout the United States, cooperative expansions have issued leaflets detailing measures to control the seed population and protect crops and property. One example is the NCR 451 Collaborative Star Management in Agriculture. Roads include the closing of holes or the suspension of heavy plastic or rubber bands over open entrances, using a wire or wire mesh, frightening with intermittent "explosive", repellent, trapping, and poisoning. For farmers in many states, the war is comprehensive.
However, there are many web sites dedicated to estimating starlings: Starling stories, how to breed a starling child, what to feed a fledgling, and more. As with all creatures, there is more to the story, but we need to start at the beginning.
The goal of the American Society for Adaptation was to identify all the birds mentioned by William Shakespeare in his collected works. (This same organization is responsible for the English population of Sparrow.) The path that inspired them? A line spoken by Hotspur to Earl Worcester in 1 King Henry IV 1.3, "I shall have a starling must learn to speak only" Mortimer, "..."
Maybe it could be. In the audiovisual guide to the North American Birds, their voice is described as "simple, low-pitched, no-musical chatter, interspersed with sirens, clicks, songs and conversations imitating. (I personally woke up from the sound of a donkey screaming only to discover that the culprit was starling). They say in an endless pregnancy and especially high at the beginning of the breeding season, when the male promotes his or her skill-building and the advertising of his companion.
Its first function is to select the site, whether it is a natural flight, an appropriate opening in a building, a pillar, a traffic sign or a road sign. Then follow the basic construction of sticks and branches. If the female agrees to his work, they place the nest with milder materials such as algae and leaves. If not, they do what they do, and start again to complete preparations for the newcomers together. The absolute family man, the male protects and defends his companion and his family, helping to raise and feed one, two or three brood.
Male pheasants are often at the highest point above the nest and sing, although the jumper in the circle of the magnetic bird has an attractive role like a deaf neighbor's tone in the bathroom.
Perhaps this is one of the attributes that you carry to people. Their gift may be a tradition, a clumsy walk or a soldierlike behavior, but regardless, the long-term effects of their existence and massive population growth are a reality.
So what can you do?
Ideally, you want to block boat-filled accommodation with the welcome mark of local species at the same time.
First determine whether your starling nestles on your property. If so, consider closing the entry. If they are young and can not bear the idea of destroying them, wait until they leave the nest and cover it. Remember they will multiply again, so your timing is the key.
If you want to encourage local species such as chickadee and nuthatch, clean the cavity (if possible), then place a reducer (plate with the right size hole). The nesting boats in the pit can not fit, but here the difference between the experts is different.
Most PGE publications identify holes no more than 1 inch in diameter, but Tina asserts that, since publications target agricultural installations with barns and silos, they are deliberately wrong. Their primary objective is to deter all species, parents and foreigners.
At the Cornell's of Ornithology Laboratory, the maximum absolute volume of access to absolute songs is 1.5 inches. "A hole of 1.25 inches will work, but not for Bluebird," says Tina.
Local shops specializing in backyard birds are recommended 1.25 inches to 1.5 inches of holes for the Chickadees, Nuthatches and Bluebirds. If the starling continues, the dilator is usually an effective deterrent. The extender tube is installed on the aperture to create a tunnel length of one to two inches. While the starling may be swinging in a smaller hole a quarter of an inch deep, it will find itself deeper.
If you decide to provide nest boxes with holes larger than 1.5 inches (the western bluebird needs 1.5 inches, the Bluebirds need 6 cm larger again), should be monitored, and birds or birds should be discarded again and again. As determined and determined as they are.
If you've tried the nutrients in the backyard to find out you've set up an exclusive restaurant, there's hope. While Starling is not picky of cannibals, there are a few things that they do not care about.
Provide sunflower seed oil in a black feeding tube. Starlings do not usually care for them, but if they decide to take samples from the list, they will find it difficult to stick to the disc.
The thorns of Niger are preferred by Finch but also tempt local birds, mourning the doves, and Pine Siskin. Most specialist poultry shops are provided by pound or soft cloth bags that can only be fed by small items.
Adding fat to the list is where things get more complicated. Oats and peanuts are superior to fins, but for Nuthatches, Chickadees and Bushtits, this can be crucial for their survival, especially in winter. Chandeliers were traditionally made in an open snore cage or nylon mesh, which they easily mated with. Instead, look for upside down feeders: mainly plastic or wooden ceilings above the wire cage. Younger citizens will easily hang upside down to choose grease, while the fiercest angler will have to search for food on the ground for droplets that are accidentally dropped.
If you use a budget, but you want to provide grease, try this: You will need a nylon mesh bag containing a range of fresh products (such as onion bag), a blank plastic container of any kind (vegetable margarine), yogurt, and a piece of grease from the section Meat. (You may have to ask the butcher.)
Place the grease in the plastic container and flip it upside down in the mesh bag. Cut it or attach it to the top and attach it. You can also create your own foods by melting fat on low heat and adding sugar-free peanut butter without salt (1: 1 ratio). When butter and peanut butter are mixed well, add corn flour, unsalted peanuts or sunflower seeds and stir well. Fill the plastic container with the mixture and place in the refrigerator until hardened. When it's time to hang it out, leave it in the container and hang it upside down.
