throat (not merely a white chin, as in the swamp 
sparrow) and a broad white stripe on each side 
of the crown, turning to yellow in front of the

per sparrow, more generally known, perhaps, as 
the bay-winged bunting, likes a drier field than 
the song sparrow, and is especially noticeable for 
his trick of running along the path or the road 
directly in front of the traveler.
