Come fly with me
Look up to the sky and you might see birds flying in a V shape. This pattern is thought to give the birds behind an aerodynamic advantage. Now it seems birds really do fly with a little flap from their friends. In this Nature Video, we see how researchers at the UK s Royal Veterinary College put data loggers on ibises to record their position, speed and wing flaps when they migrated. The ibises position themselves within the V so that they benefit from the flow of air created by the bird in front.
