Natures wonders: biomimetics; swan neck cameras (Introduction)

Studying how swans and geese keep their heads steady while twisting and turning in the air has led to ways of keeping drone cameras steady:

"Swans and geese are the envy of aeronautical engineers. Even plump geese can perform remarkable aerial acrobatics - twisting their body and flapping their powerful wings while keeping their head completely still.

"They found that the neck functions much like how a car's suspension system provides a smooth ride over a bumpy road. The neck vertebrae and muscles respond with just the right stiffness and flexibility to passively keep the head steady during flapping flight, and even in mild gusts.

"'This simple mechanism is a remarkable finding considering the daunting complexity of avian neck morphology with about 20 vertebrae and more than 200 muscles on each side," said Lentink, the senior author on the study."
