Egyptian wader (4)
I believe the answer is:
ibis
'egyptian wader' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for ibis that I've seen before include "sacred creature of Egypt" , "Wading bird of warm regions" , "Glossy wading bird" , "Slowly discharge" , "Long-legged wading bird" .)
