Eastern gale blasted bird (5)
I believe the answer is:
eagle
'bird' is the definition.
(eagle is a type of bird)
'eastern gale blasted' is the wordplay.
'eastern' becomes 'e'.
'blasted' indicates an anagram.
'gale' anagrammed gives 'agle'.
'e'+'agle'='EAGLE'
(Other definitions for eagle that I've seen before include "Keen-eyed bird" , "Bird with hooked bill and long broad wings" , "King of birds" , "may be soaring" , "Bird of prey, may be golden" .)
