Singer not oral, strangely (7)
I believe the answer is:
ortolan
'singer' is the definition.
(ortolan is a kind of birdanimal)
'not oral strangely' is the wordplay.
'strangely' indicates an anagram.
'not'+'oral'='notoral'
'notoral' is an anagram of 'ORTOLAN'.
(Other definitions for ortolan that I've seen before include "high-flying singer" , "Small songbird" , "One flying" , "Bobolink" , "Flier" .)
