252, Spi^ella socialis (Wils.). Chipping Sparrow. 



Breeding Range — Eastern N. A., northward to Great Slave Lake. 

 Winter Distribution — Southern States. 



Abundant summer resident, arriving in the vicinity of Philadel- 

 phia Marcli 30 and departing about October 20. Along the New 

 Jersey coast it occurs as late as November (Seaville, Cape May Co. 

 — W. L. Bcdly), and a few may perhaps winter occasionally. 



253, Sjji^ella pusilla (Wils.). Field Sparrow. 



Breeding Range — Eastern U. S. and southern Canada. 

 Winter Distribution — Mainly south of the Middle States. 



An abundant summer resident. In the vicinity of Philadelphia, 

 a few winter every year, but the bulk go a little farther south, leav- 

 ing about the end of October and returning March 18. 



In southern New Jersey they winter in great numbers. 



254, Jimco hyenialis (Lixn.) Snowbird.* 



Breeding Range— Maine to Alaska and southward in the Alleghanies 



to Pennsylvania. 

 Winter Distribution — Throughout eastern U. S. 



Abundant winter resident from about October 1 fo April 15, oc- 

 casional stragglers lingering until the first week of May. 



The Junco is a regular breeder along the main ridge of the Alle- 

 ghany Mountains, and has been found in summer in Sullivan, Wyom- 

 ing and Luzerne counties ( Wan-en^s Report, Divight, Stone, etc.). 



Mr. Dwight states that some of the specimens of Junco from the 

 Pennsylvania mountains are indistinguishable from Jtmco h. caro- 

 linensis of the North Carolina mountains, while others differ little 

 from true /. hyemalis. The position of the Pennsylvania mountains 

 would lead us to expect the Snowbirds to be more or less intermediate 

 between the two races. 



* An interesting hybrid between this species and the White-throated Spar- 

 row was taken at Haverford, Montgomery county, Pa., December 12, 1882, by 

 Mr. W. L. Baily, and is now in the collection of the Academy of Natural 

 Sciences of Philadelphia {B. N. 0. C, VIII., p. IB, and Auk., 1893, p. 213).
