The eyes are also the

In humans, the eyes are considered 'windows of the soul', conveying a lot of emotions and intentions. A recent study has demonstrated for the first time that birds also respond to human vision.

Carnivores often look at their prey when they attack, so direct gaze can predict the danger coming. Julia Carter - a Ph.D. student at Bristol University - and her colleagues conducted experiments to show that starlings keep away from their plate if someone looks at the plate. . However, if someone approached and their gaze turned to the other side, the birds would continue to eat and eat more food.

"This is a good example of how animals can pick up subtle signs and use them to their advantage," Carter said .

Wild wild starlings are highly social and quickly join other birds in a good green field. This will lead to situations where competition for food is highly competitive. A starling bird assesses the risk of being eaten relatively low and responding by returning to faster grasslands (as in this study) will scramble for valuable time to eat before those another bird flew to this land.

Reactions to obvious signs of danger - such as a predatory predator appearing high up or running away from other animals - are also valuable documents, but Carter argues that The positioning and head orientation of the new predator are signs of a more sophisticated risk and are useful because many animals eat their heads and eyes towards prey when they attack.

This study describes the detailed expression of a bird's response to the orientation of a live carnivore. Carter added: 'By responding to these fast-sighted signals, starlings have gained a competitive advantage between other unspecified subjects. This study underscores the importance of looking at very sophisticated signals that can be used in the decision process of an animal. "

Can these birds understand someone watching them, and can they pose some risk? So far there has been no answer to this question. However, whether these reactions are related to some kind of psychological theory, are these reactions innate or acquired through experience, and the results show that starlings can be distributed? It is also possible to get sophisticated eye-sighted signals from a nearby carnivore and adjust the reaction to predators in the most beneficial way .

These results were published online in the Journal of the Royal Proceedings of the Royal Society B.
