American songbird (6)
I believe the answer is:
oriole
'american songbird' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for oriole that I've seen before include "Bird of which male has black and yellow plumage" , "Songbird with yellow and black plumage -- Leo or I (anag)" , "Baseball player in Baltimore" , "Bird, Baltimore --" , "Bright-plumaged bird" .)
