Bird found colourful article in French port (9)
I believe the answer is:
redbreast
'bird' is the definition.
(redbreast is a kind of bird)
'colourful article in french port' is the wordplay.
'colourful' becomes 'red' ('red' can be similar in meaning to 'colourful').
'article' becomes 'a' (indefinite article).
'in' indicates putting letters inside.
'french port' becomes 'brest' (a port city in brittany).
'a' placed inside 'brest' is 'breast'.
'red'+'breast'='REDBREAST'
'found' is the link.
(Other definitions for redbreast that I've seen before include "Bird" , "Flapper" , "One tweets" , "Type of robin" .)
