Turkey, before pot of pheasant (8)
I believe the answer is:
tragopan
'pheasant' is the definition.
(tragopan is a kind of pheasant)
'turkey before pot' is the wordplay.
'turkey' becomes 'tr' (I've seen this in other clues).
'before' becomes 'ago' (I've seen this before).
'pot' becomes 'pan' (I've seen this before).
'tr'+'ago'+'pan'='TRAGOPAN'
'of' acts as a link.
(Other definitions for tragopan that I've seen before include "pheasant" , "Brilliant winger" .)
