Blink of an eyelid


Photo Information
Profile of Golden Eagle 'Star' at Rosliston, showing the extra eyelid (Nictitating Membrane).

As well as being use to wipe the eyes clean, being translucent, it is also used as a 'visor' during high speed flight (up to 200mph!)

K-r with DA 55-300, on rapid fire to catch the 'blink'
