April 29 ('94) quite a number were in a flock with Field and 

 Chipping Sparrows. At Washington "from late in October to 

 early in April " (Richmond). 



Spizella socialis (560). Chipping Sparrow, 



First noted on March 16 ('94), and common from March 25 

 ('94) to November 27 ('92), 8 or 10 were seen on December 2 

 ('94), and about a dozen on December 4 ('92). At Washington, 

 "some spend the winter, but not in numbers sufficient to be 

 detected every season. On March 12 ('90, J. D. Figgins) four 

 were seen. Common from the end of March to November 24 

 ('89), one was seen on December 14 ('90)" (Richmond). Mating 

 on April 22 ('94), the first nest with eggs was found on May 

 10 ('91), the last on August 28 ('92), and on September 16 ('94) 

 young just out of the nest were observed. Sets are 2 of 2, 27 

 of 3, and 14 of 4. 



At Hagerstown their arrival is noted on March 30, '79, March 

 18, '80, and March 21, '81. Under date of April 15, '83, is the 

 following : " Has any one ever noted the Chippy's fondness 

 for the sap of the grape vine? They make a regular habit of 

 drinking large quantities when the vines have been trimmed in 

 spring. Do they do this for water, or for any nourishment there 

 is in the sap? I rather think the latter, as they drink too much 

 for simply quenching their thirst" (Small). 



Only a few at Vale Summit, June 5 to 14, '95. 



Spizella pusilla (563). Field Sparrow. 



This is our most common breeding sparrow, being exceedingly 

 numerous from March to November. During- mild winters, a 

 number stay with us, and even during the cold winter of '92-3 

 a flock was seen on December 4, about 20 on January 4, and a 

 single bird on January 22. At Washington it is noted as "a 

 common regular winter as well as a summer resident" (Rich- 

 mond). Nests with eggs are noted from May 8 ('91) to August 

 16 ('91). Sets are 5 of 2, 22 of 3, and 15 of 4. 



At Vale Summit they were not common, June 5 to 14, '95.
