Sacred Egyptian bird (4)
I believe the answer is:
ibis
'sacred egyptian bird' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for ibis that I've seen before include "Bird, sacred to ancient Egyptians" , "Bird venerated by ancient Egyptians" , "may be sacred?" , "Sacred Egyptian bird" , "Near-colourless mineral" .)
