Communist beginning to get a bird (8)
I believe the answer is:
redstart
'a bird' is the definition.
(type of bird)
'communist beginning' is the wordplay.
'communist' becomes 'red' (red can informally mean communist).
'beginning' becomes 'start' (synonyms).
'red'+'start'='REDSTART'
'to get' acts as a link.
(Other definitions for redstart that I've seen before include "Singer" , "Half of 1D [GAME OR BIRD]" , "bird from Europe" , "One sings" , "Flier" .)
