Pigeons’ shifting gaze could help drones navigate more like birds: UBC study

Key Points:

• Researchers at the University of British Columbia equipped homing pigeons with miniature backpacks containing computers and head-mounted cameras to track their eye movements during flight, aiming to inform smarter drone design.
• The study revealed pigeons actively move their eyes to gather detailed environmental information and use both eyes simultaneously to judge depth when landing, challenging prior assumptions that pigeons keep their eyes fixed during flight.
• Differences in findings compared to a recent study suggest pigeons may stabilize their gaze when flying low but scan more broadly at higher altitudes, possibly to detect predators.
• Insights from pigeons' dynamic vision could inspire drones with movable cameras, enhancing their ability to navigate and track objects more effectively than current rigid-camera systems.
• Experts note that incorporating adaptable, bird-inspired camera systems could significantly improve drone performance in tasks like wildlife observation and autonomous navigation.
