Bird talk (4)
I believe the answer is:
chat
I believe this clue is a double definition.
'bird' is the first definition.
(chat is a kind of bird)
'talk' is the second definition.
(I know that chat is a type of converse)
(Other definitions for chat that I've seen before include "waffle?" , "Small songbird of the thrush family" , "Talk casually" , "Exchange text or voice messages through a computer" , "Communication" .)
