Hummingbird Vision Wired to Avoid High-Speed Collisions

Hummingbirds are among nature’s most agile fliers. They can travel faster than 50 kilometres per hour and stop on a dime to navigate through dense vegetation.

Now researchers have discovered that the tiny birds process visual information differently from other animals, perhaps to handle the demands of their extreme aerial acrobatics.

“Birds fly faster than insects and it’s more dangerous if they collide with things,” said Roslyn Dakin, a postdoctoral fellow in the UBC’s department of zoology who led the study. “We wanted to know how they avoid collisions and we found that hummingbirds use their environment differently than insects to steer a precise course.”
