Repeatedly swindle getting bird (4)
I believe the answer is:
dodo
'bird' is the definition.
(dodo is a kind of bird)
'repeatedly swindle' is the wordplay.
'repeatedly' says to double the letters.
'swindle' becomes 'do'.
'do' doubled is 'DODO'.
'getting' acts as a link.
(Other definitions for dodo that I've seen before include "one very dead!" , "Repetitive extinct animal" , "Square" , "Old-fashioned person" , "one finished?" .)
