Nictitation membrane

The Nictitation Membrane of Eagles:

		The nictitation membrane is a transparent inner eyelid in birds, reptiles, and some mammals that closes to protect and moisten the eye. It is also called the third eyelid.
		Pam captured these images of young eagles close to camera 5 in the spring of 2005 to help us demonstrate this adaptation. You can find further information about this feature at: http://ebiomedia.com/gall/eyes/protect.html

Pam Birley of Leicester England captured remotely these pictures of eagles from
the robotic camera 5.
