Ammodramus sandwichensis savanna (542a). Savanna 



Sparrow. 



Fairly common migrant, some possibly wintering ; noted from 

 October 6 ('95,) to November 9 ('92, Resler), and from 

 March 18 ('91, Resler) to May 12 ('92, Pleasants). At Wash- 

 ington " 4 were noted on October 14, '94, (J. D. Figgins and 

 Wm. Palmer) ; a few winter " (Richmond). At Hagerstown 

 " quite common during the fall migration of '80 " (Small). 

 No doubt it winters along our sea-coast for " at Cape May 

 and probably all along the coast of southern New Jersey the 

 Savanna Sparrow is an abundant winter resident" (Birds, E. 

 Pa. and N. J., 113). 



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.

 one or two localities. On May 30, '92, while exploring John-

 colony was found " (E. M. Hasbrouck, Auk, x, 92). " Not
