Bird’s noise starts to attract roadside dwellers (7)
I believe the answer is:
buzzard
'bird's' is the definition.
(buzzard is a kind of bird)
'noise starts to attract roadside dwellers' is the wordplay.
'noise' becomes 'buzz' (I have seen 'Noise of bees ' mean 'buzz' so perhaps 'noise' could also mean 'buzz').
'starts to' says to take the initial letters.
The first letters of 'attract roadside dwellers' is 'ard'.
'buzz'+'ard'='BUZZARD'
(Other definitions for buzzard that I've seen before include "See 20" , "Predatory hawk" , "Kind of big hawk or grasping person" , "Raptor" , "American vulture or European hawk" .)
