One follows exotic birds in Italian port (8)
I believe the answer is:
brindisi
'italian port' is the definition.
(I've seen this before)
'one follows exotic birds in' is the wordplay.
'one' becomes 'i' (Roman numeral).
'follows' means one lot of letters go next to another.
'exotic' indicates anagramming the letters.
'birds'+'in'='birdsin'
'birdsin' anagrammed gives 'brindis'.
'i' put after 'brindis' is 'BRINDISI'.
(Other definitions for brindisi that I've seen before include "Song that goes with drinking" , "Southeast Italian port" , "Italian port on the Adriatic" , "toast of some Italians" , "Italian drinking song" .)
