Scientists at the University of British Columbia have been studying how hummingbirds avoid high-speed collisions, Science Daily reports.
"Birds fly faster than insects and it's more dangerous if they collide with things," said Roslyn Dakin, 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."
In the study, hummingbirds were placed in a specially-designed tunnel with patterns projected onto the walls. Researchers set up eight cameras to track them as they flew through the tunnel."We took advantage of hummingbirds' attraction to sugar water to set up a perch on one side of the tunnel and a feeder on the other, and they flew back and forth all day," said Douglas Altshuler, associate professor in the department of zoology. "This allowed us to test many different visual stimuli."
