English: An image of a Common Kestrel Falco tinnunculus. The bird of prey is photographed hovering against a clear blue sky. It was spotted and then photographed, as it flew above the cliff tops of east coast of Yorkshire, England, UK. The image is processed to be viewed via 'Anaglyph' [red/ blue filtered] glasses, which enables the volume and density of the bird's body to be more easily sensed and gauged to the eye, which then comes out with the illusion of greater significant depth.
