One bird following another (4)
I believe the answer is:
fowl
'one bird' is the definition.
(fowl is a kind of bird)
'following another' is the wordplay.
'following' becomes 'f' (used when citing page numbers etc).
'another' becomes 'owl' (I can't explain this - if you can you should believe this answer much more).
'f'+'owl'='FOWL'
Can you help me to learn more?
(Other definitions for fowl that I've seen before include "Poultry bird" , "Domesticated bird" , "Bird, maybe domestic" , "Bird kept for eggs and meat" , "eg Chicken" .)
