Bird is flying around in Italian port (8)
I believe the answer is:
brindisi
'italian port' is the definition.
(I've seen this before)
'bird is flying around in' is the wordplay.
'flying' indicates an anagram.
'around' indicates putting letters inside.
'bird'+'is'='birdis'
'birdis' anagrammed gives 'brdisi'.
'brdisi' going around 'in' is 'BRINDISI'.
(Other definitions for brindisi that I've seen before include "Ibis rind (anag) - Italian port" , "Italian drinking song" , "Southeast Italian port" , "Song that goes with drinking" , "toast of some Italians" .)
