Bird joining others in murder? (4)
I believe the answer is:
crow
This clue could be a double definition.
'bird' is the first definition.
(crow is a kind of bird)
'joining others in murder?' is the second definition.
I know that 'murder' relates to this answer.
Can you help me to learn more?
(Other definitions for crow that I've seen before include "Large black bird" , "Ugly old woman" , "bar" , "'As the - - flies'" , "One commonly stoned" .)
