till the last of November ; appears in spring early in March ; 

 is very abundant till the middle of April, and stragglers 

 are seen till May. Are in full song on their arrival in 

 spring, and at all times are seen in loose flocks. While the 

 snow is passing off in spring they seem to be more num- 

 erous than all other birds. Breed among the mountains 

 of Berkshire County, according to Prof. Emmons, and as 

 far south in Hampden County as Blandford and adjoining 

 towns. 



119. Spizella monticola Baird. Tree Sparrow. Com- 

 mon winter visitant. Seen from October 20th to about 

 May 1st. In winter inhabits sheltered ravines and swamps, 

 and feeds much on the seeds of weeds that remain above 

 the snow in open fields. Are gregarious, and when feed- 

 ing, particularly in severe weather, keep up a peculiar 

 .tinkling twitter. This species was found breeding in the 

 eastern part of the State in the summer of 1855, its nest 

 and eggs being found by Mr. E. Samuels. (Proc. B. S. 

 N. H., vol. v, p. 213.)^ 



120. Spizella socialis Bonap. Chipping Sparrow. 

 Very common summer visitant, breeding everywhere in 

 the vicinity of farm-houses, in the city, and even in re- 

 mote fields, nesting in trees. Arrives about April 1st ; 

 leaves second or third week of October. Is not so grega- 

 rious while here as its congeners. 



121. Spizella pusilla Bonap. Field Sparrow. Wood 

 Sparrow. Common summer visitant. Breeds in old bushy 

 fields, nesting on the ground. In one or two instances 

 only have I found it nesting in bushes. The males sing 

 the whole summer, and almost constantly from April till 

 July. Arrives about April 1st, collects into loose flocks 

 in August and September, and leaves about the middle of 

 October. In autumn emit tinkling notes, similar to those 

 of S. monticolfif. 



122. Melospiza melodia Baird. Song Sparrow. Abun- 

 dant summer visitant. Breeds about meadows and in 

 moist situations. Arrives the last of March, and is ex- 

 tremely abundant during April, but is not properly grega- 

 rious, though occasionally found in considerable flocks 

 when feeding ; retires south late in October.
