Celebrity student in Greece originally finding bird (8)
I believe the answer is:
starling
'bird' is the definition.
(starling is a kind of bird)
'celebrity student in greece originally' is the wordplay.
'celebrity' becomes 'star' (I've seen this before).
'student' becomes 'l' (as in L-plates for learner drivers).
'originally' says to take the initial letters.
The initial letter of 'greece' is 'g'.
'star'+'l'+'in'+'g'='STARLING'
'finding' is the link.
(Other definitions for starling that I've seen before include "Passerine bird" , "Slant rig for the strange bird" , "Common garden bird" , "Common songbird" , "Noisy bird with speckled feathers - somewhat stellar" .)
