'A bird, otherwise?!' I yell in Spanish (6)
I believe the answer is:
oriole
'a bird' is the definition.
(oriole is a kind of bird)
'otherwise? i yell in spanish' is the wordplay.
'otherwise?' becomes 'or'.
'yell in spanish' becomes 'ole' (cheer used in Spanish).
'or'+'i'+'ole'='ORIOLE'
(Other definitions for oriole that I've seen before include "Black and yellow US bird" , "Did Leo or I hear the tropical songbird?" , "Bird, Baltimore --" , "Songbird with yellow and black plumage -- Leo or I (anag)" , "Bright songbird" .)
