A selection of animated GIFs taken from a video uploaded by Alex Holcombe which
shows how the owl’s vestibular system allows its neck to quickly counterrotate to compensate for the body’s movement
From GrrlScientist in the Guardian:
we watch a geeky NASA scientist move an owl’s body around a number of axes in space to show how effortlessly the bird stabilises its head.
This video was part of a research project into the vestibular sensory system of owls, conducted by NASA.
