Head kept motionless in flight: kestrel


Common kestrel / Andreas Trep.. / LicenseCC-by-sa - Attribution Share Alike

The head of the kestrel remains motionless in flight due to the bird's ability to hover by facing into the wind and matching its speed.

"The kestrel is a wild bird that is well-known in Europe, Asia and Africa. It has a special ability: it can maintain its head in a perfectly still position in the air by facing the wind. Though its body may sway in the wind, its head remains motionless, which increases the excellence of its vision in spite of all the motion." (Yahya 2002:56)

This strategy was marked as "In Discussion" because of user-expressed concern over the source. However, this is born up through observation of kestrels in the USA and so we've made it active again. However, it would benefit from more research to get deeper into the mechanism.
