Live around flightless birds in muddle (6)
I believe the answer is:
bemuse
'muddle' is the definition.
(I've seen this in another clue)
'live around flightless birds' is the wordplay.
'live' becomes 'be' (synonyms).
'around' means one lot of letters goes inside another.
'flightless birds' becomes 'emus' (emu is a kind of flightless bird).
'be' enclosing 'emus' is 'BEMUSE'.
'in' is the link.
(Other definitions for bemuse that I've seen before include "Stupefy, puzzle" , "Muddle or stupefy" , "Bewilder or baffle" , "Puzzle and confuse" , "Confuse, bewilder" .)
