Bird hidden by the murmuration (3)

I believe the answer is:

emu

'bird' is the definition.
(emu is a kind of bird)

'hidden by the murmuration' is the wordplay.
'hidden' says the answer is hidden in the clue.
'EMU' is hidden within 'by the murmuration'.

(Other definitions for emu that I've seen before include "Aussie runner" , "Fast runner in Oz" , "Aussie bird" , "Long-necked bird" , "Australian non-flyer" .)

I've seen this clue in The Times.
