Ammodramus savannarum passerinus (546). Grasshop- 

 per Sparrow. 



A few wintering; this species is common from April 10 ('95, 

 Fisher) until November 4 ('94). It is usually flushed from the 

 ground, but during the breeding season it mounts on a weed or 

 even to the top of a fence to sing the very peculiar song from 

 which it derives its name. 



Although very numerous in the breeding season, the nest is 

 seldom found, it being placed on the level ground in the open 

 field. Young out of the nest were being fed on June 4 ('93), 

 and on August 11 ('94) birds 4 or 5 days old were in a nest. 

 Sets are 3 of 3, and 3 of 4. 



Common at Washington from March 30 ('95) to October 21 

 ('87, Richmond). At Vale Summit a number were observed 

 June 5 to 14, '95.
