Study Finds Birds Conserve Energy and Generate Extra Lift by Flying in V Formation
Posted on January 16, 2014
Scientists at the UK's Royal Veterinary College put tracking devices on ibises in a study about why birds flock together in a V formation. The study found that the birds are choreographing their flight and intentionally positioning themselves in aerodynamically optimum positions. The V shape helps the birds save energy. Birds benefit from an upwash effect by utilizing the air flow from the bird or birds flying in front of them. The scientists say, "it seems birds really do fly with a little flap from their friends."
The results of the study were published here in Nature. The scientists say, "These aerodynamic accomplishments were previously not thought possible for birds because of the complex flight dynamics and sensory feedback that would be required to perform such a feat."
The lead researchers Dr. Steven Portugal, told BBC News, "They're seemingly very aware of where the other birds are in the flock and they put themselves in the best possible position."
The scientists explain the aerodynamics behind the upwash effect around the 4 minute mark in this Nature video. Take a look:
