Research published in Avian Biology Research shows that pigeons can reliably discriminate between familiar and unfamiliar humans and that they use facial features to tell people apart. The results revealed that pigeons are able to discriminate reliably between familiar and unfamiliar humans and provide evidence that facial features are important for this recognition.
How The Street Pigeon Got Its Fancy On Amazing Science Innovation Strategy Mutualistic Relationship Science
It is very likely that the pigeons recognised the researchers by their faces since the individuals were both female and of a similar age build and skin colour says Dr.
Pigeon face recognition. The head are important for species recognition and mate selection. Face Recognition and Memory Faces convey a wealth of information that is critical to social interactions such as identity and emotion. The theory proposes that the visual input is matched against structural representations of objects in the brainThese structural representations consist of geons and their relations eg an ice.
This study investigated whether pigeons are capable of performing such a sophisticated categorisation and the features relevant to making this discrimination. The human face could have been specialized through evolution to transmit signals that would be easily decoded by existing visual processes. Received in revised form 4 November 2003 Available online 21 February 2004.
For example both humans and pigeons can recognize an individual human face despite some changes in facial expression while the ability to discriminate emotional expression is associated with a particular face 27. The next time a bird looks at you quizzically they may just be studying your face so they can identify you again in the future especially if you bring a bag of bread crumbs with you.

Wilkinson and the team found that the pigeons were able to discriminate between the photographs based only on 2D facial information and the results were published in Avian Biology Research. Spetcha Ken Chengb and Colin WG. This allowed the researchers to disentangle the impact of facial cues from other additional features such as smell and clothing colour.
Pigeons Recognize Human Faces If you shoo a pigeon that bird is likely to remember you and know to stay out of your way the next time you cross paths according to a new study. The results revealed that pigeons are able to discriminate reliably between familiar and unfamiliar humans and provide evidence that facial features are important for this recognition. If such visual processes are also present in birds then the fact that some aspects of face recognition are similar in pigeons and people seems less surprising.
Dalila Bovet a co. Geons are the simple 2D or 3D forms such as cylinders bricks wedges cones circles and rectangles corresponding to the simple parts of an object in Biedermans recognition-by-components theory. The Animal Face Recognition AFR feature allows visitors to obtain information on individuals specimens by using their Smartphones through the Pigeon interface.
The study highlights the importance of comparative studies between species especially when it comes to understanding the evolution of human perceptual and cognitive processes. Recognition including human facial recognition may be similar between the two groups 2829. Furthermore our results suggest that the ability to discriminate between individual heterospecifics is not restricted to bird species that are considered highly.
Moreover because all faces contain the same features eyes nose mouth in the same general configuration eyes above nose nose above mouth distinguishing between individuals is a visually demanding task. So pigeons just like humans recognize facial identity independent of emotional expression yet tend to associate emotional expression with identity. Spaces such as aquariums and zoo parks exhibit a plethora of aquatic and animal species both under-water and on ground for visitors.
For the first time in the history of navigation technology Pigeon app has integrated an animal face recognition feature within the existing list of features for aquarium and zoo navigation. Lol maybe need do a face painting before head out like warpaint perhaps or deep jungle encroachment lmao or could try the football black under eyes lol William Dawson Jun 25 2017 2. However little is known about the exact visual features necessary to elicit displays.
The current study examined the preference behavior of male pigeons when given a choice between photographic images of normal looking or altered female pigeon faces. The human face could have been specialized through evolution to transmit signals that would be easily decoded by existing visual processes. Chickens Gallus gallus domes-.
Peak shift but not range effects in recognition of faces Marcia L. When you feed the pigeons in the park you may find yourself surrounded with more and more birds if you are a regular. If such visual processes are also present in birds then the fact that some aspects of face recognition are similar in pigeons and people seems less surprising.
The results revealed that pigeons are able to discriminate reliably between familiar and unfamiliar humans and provide evidence that facial features are important for this recognition.
