Quicksilver the African Grey Parrot and his Nictitating Membrane (Nictitating Eyelid)

Having never seen any evidence of a nictitating membrane after almost 15 years of watching  Silver full time plus other parrots on and off ,  I was quite surprised to see the above.  

Silver definitely has a nictitating membrane.

I've been watching "third eyelids" shield and unshield on Red-tailed Hawk eyes for years.

Boy, do I feel dumb.   

But then again, Silver's eyes are a lot smaller than theirs.

That's something anyway.
