The French bird over country seeing all the wildlife (6,7)
I believe the answer is:
animal kingdom
'all the wildlife' is the definition.
'the french bird over country' is the wordplay.
'the french bird over' becomes 'animal' (I can't justify this - if you can you should believe this answer much more).
'country' becomes 'kingdom' (kingdom is a kind of country).
'animal'+'kingdom'='ANIMAL KINGDOM'
'seeing' is the link.
Can you help me to learn more?
(Other definitions for animal kingdom that I've seen before include "beasts in general" , "Moving organisms in general" , "beastly lot" , "Creatures collectively" .)
