Friendly talk with bird (4)
I believe the answer is:
chat
This clue is a double definition.
'friendly talk' is the first definition.
(I've seen this before)
'bird' is the second definition.
(chat is a kind of bird)
'with' acts as a link.
(Other definitions for chat that I've seen before include "flier" , "Exchange text or voice messages through a computer" , "Informal conversations" , "waffle?" , "One given to song" .)
