Flock of quails (4)
I believe the answer is:
bevy
'flock of quails' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for bevy that I've seen before include "Large group (of people)" , "Group of girls, quail" , "female company?" , "Flock (eg of quails)" , "many girls" .)
