is generally supposed. In the fall of 1876 Mr. Scott took over fifty of 

 these birds, the series being a part of the University Collection. On 

 May 6, 1899, I took two of these sparrows and saw three more, and in 

 October of the same year secured a third ; but, as a rule, the White- 

 crowned Sparrow is a rather uncommon migrant in this locality. 



136 (558). White-throated Sparrow. Zonotrichia 

 albicollis {Gniel.). 



Arriving from the north early in October, these sparrows soon be- 

 come very abundant in all swamps and damp thickets. The great 

 majority, however, continue southward, and by the first of November 

 only a few remain, which spend the winter in sheltered places where 

 food is abundant. The return migration takes place during April, and 

 by May 15, the last stragglers have departed for the more northern 

 breeding grounds. 



137 (559). Tree Sparrow. Spizella monticola (6"^^/.). 



A very abundant fall and winter resident in all hedges and thickets. 

 Before leaving in the spring they are in full song. Ordinarily these 

 sparrows prefer the more open fields and hedges, but in severe winters 

 or after a heavy snow fall, when food is scarce, they become very famil- 

 iar and are abundant throughout the town. Appearing from the north 

 about November 3, they remain until April 10. 



138(560). Chipping Sparrow. Spizella socialis (W^z/j-.). 



A very abundant summer resident, undoubtedly breeding several 

 times during the season, as I have found nests as early as May 15, and 

 as late as August 10. In spring, the earliest record for arrival is March 

 26. The great majority, however, return about two weeks later. By 

 November 3 all have departed for the south. 



139 (563). Field Sparrow. Spizella pusilla (W^zVi'.). 



An abundant summer, and not infrequent winter resident. The 

 general arrival, however, takes place during the first week in April, and 

 only the winter residents remain after the first week in November. Of 

 the twenty nests which have come under my observation, twelve were 

 placed in low bushes, the others on the ground. Undoubtedly several 

 broods are reared each season, for I have found nests as early as May 

 12, and as late as July 18. The young remain but six days in the nest.
