A bird from Florence? (11)
I believe the answer is:
nightingale
This clue is a double definition.
'a bird' is the first definition.
(nightingale is a kind of bird)
'florence?' is the second definition.
(I've seen this before)
'from' acts as a link.
(Other definitions for nightingale that I've seen before include "Bird with beautiful song" , "Subject of 11 [ODE]" , "Keats's immortal Bird" , "The Lady with the Lamp, d. 1910" , "Noted songbird" .)
