Facial recognition software used to study the social behavior of individual Greylag Geese in Europe will soon be used to monitor one of the rarest geese in the world, the Cape Barren Goose in South Australia.
The technology was used to assess how each bird responds to images of themselves, other flock mates or partners and researchers from the University of Vienna and Flinders University say it could be used by other scientists or in citizen science apps around the world to monitor and recordFlinders BirdLab leaders Professor Sonia Kleindorfer and Dr.
With 97% accuracy, each goose face could be correctly assigned within a photo library containing 6000 possible matches, researchers say in"Next the team placed life-sized photos in a grassy field to see whether geese behave differently to each image—which they do," says Professor Kleindorfer, who founded Flinders University's BirdLab 20 years ago and now directs the Konrad Lorenz Research Centre, a core facility at the University of Vienna in Austria.
"The geese approached the photo of their partner more quickly, gave friendly contact calls and fed for longer. In contrast, when they saw a picture of themselves—a goose they had never seen before—they hissed and took longer to approach food, if they fed at all." "Animal welfare could also be enhanced through the use of photographs in captivity," says Flinders University's Dr. Colombelli-Négrel, from the College of Science and Engineering.

Facial recognition is banned in New York schools.New York State Education Department Commissioner Betty A. Rosa has issued an order prohibiting New York State schools from purchasing or using facial recognition technology. Schools may use other forms of biometric identification, the department says, but are asked to consider “the technology’s privacy implications, impact on civil rights, effectiveness, and parental input”. In a report on the subject earlier this summer, the state’s Office of IT Services noted that “there are discernable risks to the use of this technology in school settings”.
