Study is the first to measure birds’ in-flight energy expenditure directly.
It was carried out by an interdisciplinary team of researchers in the US .
The energy savings may even apply to birds that fly in dynamic flocks, not just those that adopt the familiar, fixed V-formation.
Researchers noticed that the most energy-efficient solo flyers were far more likely to adopt the “leader” role when flying with other birds.
The researchers say that this difference is likely related to the birds’ wing-flapping frequency.
A more complete explanation will require additional experiments.
