Bird associated with the Egyptian god Thoth (4)
I believe the answer is:
ibis
'bird associated with the egyptian god thoth' 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 "Wading bird sacred to the Egyptians" , "Long-legged wading bird" , "Eastern" , "leggy bird" , "sacred creature of Egypt" .)
