Re: Mei's head version 2

[Michael Schmidt <dmschmidt@sprint.ca>]

having had a moluccan cockatoo for several years, she always sleeps with her 
eyes closed.  I'm not sure if this is the case for other birds, but she also 
has a very thin membrane covering her eye that is almost like a second 
eyelid that activates on a more delicate basis than her regular one.
