Satirist succeeded getting birds (6)
I believe the answer is:
swifts
'birds' is the definition.
(swift is a kind of bird)
'satirist succeeded getting' is the wordplay.
'satirist' becomes 'swift' (Jonathan Swift).
'succeeded' becomes 's' (genealogical abbreviation).
'getting' is a charade indicator (letters next to each other).
'swift'+'s'='SWIFTS'
(Other definitions for swifts that I've seen before include "Swallow-like birds" , "Small fast birds" , "wingers" .)
