Observed: The Pigeon Columba livia
Or Not To V? But some birds, like pigeons, fly in what is known as a “cluster flock.” In such disorganized groups, says a study from the University of London, each pigeon flaps its wings more often and less completely than when alone, using more energy.
The Question: What’s the upside? That “is currently unclear,” say the researchers, but the less energy-efficient wing strokes may allow for better control within a dense flock, and flocking may help birds find food or deter predators.
