Most favourite little bird (5)
I believe the answer is:
pewee
'bird' is the definition.
(pewee is a kind of bird)
'most favourite little' is the wordplay.
'most' means to remove the last letter.
'favourite' becomes 'pet' (synonyms).
'little' becomes 'wee' (similar in meaning).
'pet' with its last letter taken away is 'pe'.
'pe'+'wee'='PEWEE'
I've seen this clue in The Hindu.
