Talk madly and name a bird (5)
I believe the answer is:
raven
'a bird' is the definition.
(raven is a kind of bird)
'talk madly and name' is the wordplay.
'talk madly' becomes 'rave' (I've seen this in another clue).
'and' is a charade indicator (letters next to each other).
'name' becomes 'n' (common abbreviation e.g. on forms).
'rave'+'n'='RAVEN'
(Other definitions for raven that I've seen before include "Bird with hoarse, croaking cry" , "Large black bird" , "Crow-like bird" , "Glossy black colour" , "Flier" .)
