Study Finds 27-Gram Pigeon Camera Rig Reveals Eye Movements That Could Sharpen Drone Vision

Summary
A 27-gram head-mounted camera system showed homing pigeons make slow, subtle eye movements during flight rather than keeping their eyes fixed, overturning a common assumption about bird vision.
Those drifting movements appear to help birds extract finer visual detail while still using motion cues for speed, direction and obstacle avoidance; researchers also found pigeons turn both eyes inward when landing on a perch.
That inward turn may enable stereopsis—depth judgment from both eyes—a trait previously documented mainly in a few birds of prey.
Researchers say the findings could improve autonomous flight because most drones use rigid cameras, while bird-like camera motion may help robots navigate complex environments more skillfully.
