Bird in gale raging over Spain (5)
I believe the answer is:
eagle
'bird' is the definition.
(eagle is a kind of bird)
'gale raging over spain' is the wordplay.
'raging' indicates anagramming the letters.
'over' says to put letters next to each other.
'spain' becomes 'e' (abbreviation for Espana**).
'gale' is an anagram of 'eagl'.
'eagl'+'e'='EAGLE'
'in' is the link.
(Other definitions for eagle that I've seen before include "Large bird of prey" , "kind of bird" , "Symbolic American bird" , "Aglee (anag.)" , "Flyer" .)
