A study reports that pigeons keep their eyes almost perfectly still while they fly. Researchers from Harvard University attach a lightweight rig using cameras and mirrors to nine pigeons and record their eye movements during short flights. The results, published in *Current Biology*, show that instead of moving their gaze around as they do in other contexts, pigeons lock their eyes in a near-fixed forward position during flight.
The study suggests that a stable, forward gaze may support visual processing and help with flight stability, potentially aiding balance and navigation. At the same time, the fixed eye position is linked to a large blind spot, which could make pigeons more vulnerable to aerial predators. The researchers also note the finding may have implications beyond biology, including possible inspiration for drone guidance or navigation systems that rely on visual input. The work adds a new detail to understanding how birds control vision and perception during active flight.
