Some birds flying in a ‘V’ shape formation. This pattern is thought to give the birds behind an aerodynamic advantage. Take a look at the video…
Now it seems birds really do fly with a little flap from their friends.
The ibises position themselves within the V so that they benefit from the flow of air created by the bird in front. They carefully time their wing flaps with their flock mates’, to get an extra lift when flying high.
In the 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.
