When you hear the name “Secretary Bird” it sounds funny. The first question that comes to mind is , why the funny name?
Let me answer with this picture today.
The name is thought to be derived from the distinctive crest of feathers . These are quill like , giving the appearance of a secretary in olden times with quill pens tucked behind the ears.
I have captured the secretary bird while blinking. Generally birds have two eyelids, upper and lower. Birds active during daytime raise the lower lid when closing their eye and nocturnal birds close the upper lid.
But birds also have a translucent, nictitating membrane, sometimes called the “third eyelid”.
This membrane moves across the eye from front to back and is used to moisten and clean the cornea, especially in flight. It is used as a defence mechanism when drawn across the eye to protect them while capturing prey, flying through brush or feeding their young.
