have observed a few in summer about the Lakes of the Clouds 

 on Mt. Washington at some 5,000 feet, and Dr. A. P. Chad- 

 bourne ('87) notes them as high as 5,300 feet. 

 Dates: April 23 to May 14; Summer; September and October. 



178. Spizella moiiticola (Gmel.). TREE SPARROW. 



A common spring and fall migrant and less common winter 

 resident. In fall the main flight passes through during late 

 October and November, and a few are left to winter at least as 

 far north as at the White Mountain valleys, as at Ossipee, 

 where Mr. E. A. Preble has noted them in winter. Frank 

 Bolles (93b) records two seen on December 2ist, at Cho- 

 corua, but it must be rarely that the birds winter there. 

 Mr. F. B. Spaulding also writes of seeing two on Dec. 9, 1899, 

 at Lancaster, the latest he had ever noticed them there in win- 

 ter. During March and April the northward flight takes place, 

 a few birds lingering nearly to the last of the latter month. 

 Dates : October 8 to April 24. 



179. Spizella socialis (Wils.). CHIPPING SPARROW. 

 A common summer resident of the Transition area, found 



mainly about orchards and door-yards, and one of the most 

 familiar and confiding of our native birds. Like the Least Fly- 

 catcher, it follows closely the path of civilization and has doubt- 

 less greatly extended its range within historic times as the for- 

 ests have disappeared before the advance of the white man. Al- 

 ready by August family flocks of old and young are seen, and 

 by the latter part of that month these join one to another, until 

 large companies are formed. At such times the birds fairly 

 swarm over weedy fields or stubble land, and often are accom- 

 panied by Bluebirds and Myrtle Warblers. These flocks move 

 leisurely southward during September, though a few individuals 

 remain among the White Mountains until well into October. 

 Prof. C. M. Weed ('98) has given a good account of the feed- 

 ing habits of this bird, as observed by him at Durham. 

 Dates : April 16 to October n.
