List includes duck – but you want another bird … (7)
I believe the answer is:
rooster
'bird' is the definition.
(rooster is a kind of bird)
'list includes duck' is the wordplay.
'list' becomes 'roster' (a roster is a list or register).
'includes' indicates putting letters inside.
'duck' becomes 'o' (resembles zero - 'duck' in cricket).
'roster' enclosing 'o' is 'ROOSTER'.
'but you want another' is the link.
I am not very happy about this link. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for rooster that I've seen before include "8 [RURAL] alarm call" , "Toreros (anag.)" , "Male domestic fowl in USA" , "Early-morning caller" , "Chanticleer" .)
