Writer consuming a governor’s pheasant (6)
I believe the answer is:
peahen
'pheasant' is the definition.
(I know that peahen is a type of bird of Juno)
'writer consuming a governor's' is the wordplay.
'writer' becomes 'pen' (something which writes).
'consuming' means one lot of letters goes inside another.
'governor' becomes 'HE' (His or Her Excellency, address for a governor).
'a'+'he'='ahe'
'pen' going around 'ahe' is 'PEAHEN'.
(Other definitions for peahen that I've seen before include "Female of the large bird, Pavo species" , "Mrs Peacock" , "Large female bird of the pheasant family" , "Female bird (with a proud partner?)" , "Female of a show-off bird" .)
