Birds wing it in many ways
The way birds move their wings, rather than the shape of those wings, determines how they fly, new research shows.
“A bird in flight does not strictly rely on having its wings fully extended and held in a stiff posture,” explains Vikram Baliga, from Canada’s University of British Columbia.
“Rather, birds fold, unfold, bend, and twist their wings as part of normal flapping behaviour.”
