Drink announced for birds gathering (4)
I believe the answer is:
bevy
This clue might be a double definition.
'drink announced for birds' is the first definition.
'bevy' can be an answer for 'drink' (short for beverage). I'm not sure about the 'announced for birds' bit.
'gathering' is the second definition.
(bevy is a kind of gathering)
Can you help me to learn more?
(Other definitions for bevy that I've seen before include "Many women" , "Flock of birds, girls or other groups" , "Group of birds or girls" , "Group, of beauties perhaps (4)" , "Flock; alcoholic drink" .)
