Bird found in Barbados and Martinique (4,6)
I believe the answer is:
sand martin
'bird' is the definition.
(sand martin is a kind of bird)
'in barbados and martinique' is the wordplay.
'in' says the answer is hidden in the clue.
'SAND-MARTIN' can be found hidden inside 'barbados and martinique'.
'found' acts as a link.
(Other definitions for sand martin that I've seen before include "Singer" , "Flyer" , "Migratory bird" .)
