Tracking shows guys’ gaze may be tuned to feathers’ symmetry, width
ANCHORAGE, ALASKA — Eye-tracking cameras show that peacocks checking out competing males keep their gaze low.
A bystander peacock attends to the other guy’s legs and the bottom tier of the huge feather display, Jessica Yorzinski of Purdue University in West Lafayette, Ind., reported June 12 at the annual meeting of the Animal Behavior Society. The high arc of feathers with iridescent eyespots may dazzle people. But what matters to the peacocks might be the symmetry and maximum width judged at the bottom of the competition’s show, Yorzinski said.
