A comb pinched by indulged bird (8)
I believe the answer is:
parakeet
'bird' is the definition.
(parakeet is a kind of bird)
'a comb pinched by indulged' is the wordplay.
'comb' becomes 'rake' (I've seen this in another clue).
'pinched by' is an insertion indicator (inserted letters get pinched or taken).
'indulged' becomes 'pet' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'a'+'rake'='arake'
'arake' going into 'pet' is 'PARAKEET'.
Can you help me to learn more?
(Other definitions for parakeet that I've seen before include "Brightly-coloured African bird" , "Colourful singer" , "flapper" , "Tropical bird" , "Flier" .)
