Crikey, matron shot bird! (9)
I believe the answer is:
cormorant
'bird' is the definition.
(cormorant is a kind of bird)
'crikey matron shot' is the wordplay.
'crikey' becomes 'cor' (I've seen this in other clues).
'shot' indicates anagramming the letters.
'matron' anagrammed gives 'morant'.
'cor'+'morant'='CORMORANT'
(Other definitions for cormorant that I've seen before include "Large diving bird" , "Diving coastal bird" , "18's [BIRD]" , "Large, voracious seabird" , "Large diving seabird" .)
