Shift capital and run, getting a flyer (10)
I believe the answer is:
budgerigar
'a flyer' is the definition.
(type of bird)
'shift capital and run' is the wordplay.
'shift' becomes 'budge' (synonyms).
'capital' becomes 'riga' (Riga is an example).
'and' is a charade indicator (letters next to each other).
'run' becomes 'r' (cricket abbreviation).
'budge'+'riga'+'r'='BUDGERIGAR'
'getting' is the link.
(Other definitions for budgerigar that I've seen before include "flighty type" , "Aussie native" , "one on the wing" , "something in cage?" , "Australian parakeet" .)
