Way to stuff duck -- flavourful bird (7)
I believe the answer is:
ostrich
'bird' is the definition.
(ostrich is a kind of bird)
'way to stuff duck flavourful' is the wordplay.
'way' becomes 'st' (abbreviation for street).
'to stuff' indicates putting letters inside (some letters stuff into others).
'duck' becomes 'o' (resembles zero - 'duck' in cricket).
'flavourful' becomes 'rich' (I can't justify this - if you can you should believe this answer much more).
'o'+'rich'='orich'
'st' put into 'orich' is 'OSTRICH'.
Can you help me to learn more?
(Other definitions for ostrich that I've seen before include "Long-necked bird" , "Emu-like bird" , "He ignores the truth" , "one tries to hide in the sand" , "Rich sot seeks large bird" .)
