So, should we call them in the city?
Researchers at the Wisconsin-Madison University have said that forest arrays, which have caused serious damage, have returned and are doing a big city.
"The best predators start out more urban areas and use multipurpose populations, and this is a pleasant example," said Benjamin Zuckerberg, professor of wildlife ecology at Wisconsin-Madison University and the new research director.
"It's no secret for the walnut: the predator is a hyperbolic [in the city]. "
Woodland hawks (subdivision Appifter) In their cities in their own cities, according to the team. Men are so adaptable that the growing number of neighboring villages is the intentional researchers of the city.
The secret of their colonization is 35 million Americans who are attracting birds every day. The hoop is not worried, but they are very interested in songbirds. This high availability of food is one of the most important factors for birds such as couper and sharp flattened hawks for the city, says Jennifer McKay, UW-Madison postdoctoral who led new research.

Hawks had no rough time because of the industrial revolution. Clearance of pesticides and hazardous use resulted in the number of different species of forests. In the 1970s, 1970s, the ban on the abolition of the US due to health and environmental concerns (1972), and later to protect migratory birds reforms in 1998 and 2004 against human beings detention or murder.
Nevertheless, the problem of destruction of the habitat remains unresolved and as the populations are distributed, the hawks move into towns, concludes the study. In Chicago, birds on birdwatchers have helped greatly strengthen the city's pillar, "says McCay.
The birds feed the bird we feed
The study emphasized more than 20 scientific data collected by participants of the project FeederWatch (initiative of Ornithology Cornell Laboratory). As for FeederWatch, people who helped document anti-counterfeiting activities in their surroundings to reduce the birds. Zuckerberg says the program is "perfect […] For such research ", as scientists allow both hawks and their predators to observe.
The main innovation of the research is that access to food is the key parameter for the city. It is unlikely that such species, such as coupe and sharp-shawed hawks are woodland predators par excellence: they are so called "perch and scan" hunters, waiting for the tree branches of food hit within the clear distance and sank on it. Cities, as you know, are particularly a branch. It is noteworthy that there was no prerequisite in the trunk of the horn, because the lovely movement was quite surprising.
Here is where the bird suppliers come into the picture. It's stable, abundant and usually low-lying sources attract many birds and creates artificial ecosystem varieties that hawks are more than splendor their hunting patterns for. Using project feederWatch data from 1996 to 2016, McKay and his colleagues have drawn this bird's rigid prequel to the rural city of Chicago. The sample also occurs in many other American and European cities (with European sporrocks, Dial nisus), They add.
"The bird's nourishment," says Zuckerberg, "looks like buffets. It's a simple meal."
"Pre-biomass was not an important driver of colonization or existence," McCute points out. "A great deal of literature says that for Cooper's chickens they prefer the more richer predators as doves and pigeons, perhaps hawking birds and not specific species."
"But in the winter they are not nesting, which means they are more concerned about their survival and lack of youth, so it makes sense that food availability will be so important."
One important lesson that the home to take this survey is that the cities are a more important habitat of wildlife. "Do not forget urban habits as a habitat," McCoy said and added that moving to urban areas would help us better "manage the everlasting world."
"The stories of the whole world are being created for growing predators in all the cities," he says. "Bear and Cooper in the US, Leipard in India and Red Moles in Europe, with a few names".
Personally, I think it's awesome that the scenery will fall into our trap. They are as zero to keep pets in my book!
