Are you looking at me?
Date:4/30/2008

In humans, the eyes are said to be the window to the soul, conveying much about a persons emotions and intentions. New research demonstrates for the first time that birds also respond to a humans gaze.

Predators tend to look at their prey when they attack, so direct eye-gaze can predict imminent danger. Julia Carter, a PhD student at the University of Bristol, and her colleagues, set up experiments that showed starlings will keep away from their food dish if a human is looking at it. However, if the person is just as close, but their eyes are turned away, the birds resumed feeding earlier and consumed more food overall.

Carter said This is a great example of how animals can pick up on very subtle signals and use them to their own advantage. Her results are published online today (30 April) in Proceedings of the Royal Society B.

Wild starlings are highly social and will quickly join others at a productive foraging patch. This leads to foraging situations that are highly competitive. An individual starling that assesses a relatively low predation risk, and responds by returning more quickly to a foraging patch (as in the study), will gain valuable feeding time before others join the patch.

Responses to obvious indicators of risk a predator looming overhead or the fleeing of other animals are well documented, but Carter argued that a predators head orientation and eye-gaze direction are more subtle indicators of risk, and useful since many predators orient their head and eyes towards their prey as they attack.

This research describes the first explicit demonstration of a bird responding to a live predators eye-gaze direction. Carter added: By responding to these subtle eye-gaze cues, starlings would gain a competitive advantage over individuals that are not so observant. This work highlights the importance of considering even very subtle signals that might be used in an animals decision-making process.
