This little mouselike sparrow might occasionally be found in New 

 York if it were not so secretive in habits. When flushed, it proceeds with 

 a weak, rail-like flight for a few feet, or a few rods, over the tops of the 

 sedges, and drops again into the grass, whence it is almost impossible to 

 raise it a second time. It frequents a denser cover than the Nelson and 

 Acadian sparrows and, consequently, is more difficult to procure.
