Pigeons Can Recognize Human Faces
It seems that years of sharing space with humans and being forced to adapt to changes in city lifestyles, has taught pigeons a few tricks that are quite remarkable to say the least. They might seem to most people just ordinary birds, but on taking a closer look pigeons are actually highly intelligent and are able to differentiate between humans, not by the clothes they wear, as they have learnt that clothing changes, but by facial recognition, which is extremely remarkable.
The perception capabilities of pigeons were tested previously in a laboratory, but researchers of the University of Paris Quest Nanterre La Defense decided to take their next experiment into the “wild” so to speak, to see how undomesticated pigeons would react. To ensure that the test would be performed as accurately as possible, two researchers were selected who shared the same build and skin color, but wore laboratory coats of different color. These two researchers then went out into the park to feed the pigeons. The first researcher threw out the food and then stood back ignoring them, giving them the opportunity to eat the food without being disturbed. The second also threw out food, but then chased them away, being hostile towards the pigeons.
For the second session, both researchers were told not to chase the pigeons, and allow them to eat, but the pigeons had remembered who the hostile researcher was and avoided her. They decided to repeat the session a few times over, even getting the researchers to swop their lab coats, but still the pigeons would avoid the researcher who was hostile on their first encounter. This confirmed the suspicions of the team, that the pigeons relied on facial recognition to detect hostiles.
Facial recognition is not a new skill in the bird world, and other researchers have discovered in previous years that birds such as magpies and jackdaws are also able to recognize humans according to their facial features. So next time you think about chasing away a bird, think twice about your actions, as you might not remember which bird you were hostile to, but they are more than likely going to remember you!
