Results of the survey conducted on a number of crows in Washington State, Seattle, United States show that Crow is still memorized the face of a man who hurt him. In fact, Crow will notify the family of man who is considered a danger.
According to Professor John Marzluff from University of Washington, a study has been conducted over the past five years shows that Crow has unique properties. These properties can help a herd of Raven in adapting and evolving with humans.
"The behavior of people or individuals against animals often change. Because human actions often threatened animals. The Crow is also learning to their social environment, including the habits of individuals who are considered to be safe, "said Marzluff, as offered via ABC News, Friday (1/7/2011).
Marzluff says the study published today in the Proceedings of the Royal Society B, inspired by previous research with crows on its campus. "I feel like they recognize us," he said.
In the experiment, researchers used the mask and then trapping, binding and then release the 7 to 15 birds in 5 different areas in Seattle. To find out the impact of such arrests, over the past 5 years later, conducted research on the bird's behavior towards people who cross the location of the arrest.
After that researchers use mask ' outlaw ' or masks that they wear while trapping group Ravens. After that they compare it to using other mask there is no relation to the arrest of the.
After almost 2 years, 11.7 percent of crows that are faced by people wearing masks dangerous rebukes masked people consistently, while numbers soaring more than doubled to about 66 percent of the nearly three years after the initial trap.
"This shows Crow memorized and bequeath them to their children" Julie insists Marzluff.
