Bird seen by an ancient deity (5)
I believe the answer is:
titan
'ancient deity' is the definition.
'titan' can be an answer for 'deity' (Titan is an example). I am unsure of the 'ancient' bit.
'bird seen by an' is the wordplay.
'bird' becomes 'tit' (tit is a kind of bird).
'seen by' means one lot of letters go next to another.
'tit'+'an'='TITAN'
Can you help me to learn more?
(Other definitions for titan that I've seen before include "Taint (anag.)" , "Atlas, possibly" , "one of great importance" , "Person of heroic stature" , "Giant of Greek mythology" .)
