Sacred bird is in the same place first (4)
I believe the answer is:
ibis
'sacred bird' is the definition.
(I've seen this before)
'is in the same place first' is the wordplay.
'in the same place' becomes 'ib' ('ib.' can be a synonym of 'in the same place').
'first' means one lot of letters go next to another.
'is' after 'ib' is 'IBIS'.
(Other definitions for ibis that I've seen before include "Flier" , "Large wader" , "Wading bird of warm regions" , "Storklike bird" , "Near-colourless mineral" .)
