Bird touching cheese (7)
I believe the answer is:
stilton
'cheese' is the definition.
(Stilton is an example)
'bird touching' is the wordplay.
'bird' becomes 'stilt' (stilt is a kind of bird).
'touching' becomes 'on'.
'stilt'+'on'='STILTON'
(Other definitions for stilton that I've seen before include "English blue-veined cheese" , "English cheese, usually veined" , "19 cheese" , "Type of cheese" , "Blue 4 across" .)
